Windows 8.1 installation in UEFI mode

Question: Windows 8.1 installation in UEFI mode

Hi there -

Can one install Windows 8.1 64-bit version in UEFI mode to one disk and leave all the other disks in the system using the NTFS mode. Also, must the Acronis 2015 Disk backup be saved on a disk with a GPT partition or not.

Many thanks in advance for any help - reading all about it on the net has totally confused me!

Preferred Solution: Windows 8.1 installation in UEFI mode

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Windows 8.1 installation in UEFI mode

Yes you can have a OS on UEIF/GPT and have BIOS/MBR Data disk. You can't have 2 OS on different formats.
Acronis should run from a USB Drive I would go with FAT32 but you'll have to check with their Support Forum as to whether their recovery program will run from A NTFS USB or DVD
Quick search gets these answers https://kb.acronis.com/search/site/C...very%2520media I guess they are still using Lunix based recovery media.

I have a few questions regarding the Windows 10 installation in UEFI mode:

I read in a couple of websites that for the installation and boot to be in "full" UEFI mode the option CSM must be disabled, can someone confirm this?

I have a GeForce GTX 460 which does not have the necessary GOP feature to have a UEFI boot, can i turn on the CSM option for a Legacy boot despite having Windows 10 installed in UEFI mode?

Can i format (in GPT mode) and partion my hard drive prior to the Windows 10 setup? Would i still need to delete all partions in the Windows setup to get the 4 partitions necessary for the UEFI installation? Or will they automatically appear since the hard drive was previously formated in GTP mode?

Thanks in advance and sorry for the bad english.

Answer:few questions regarding the Windows 10 installation in UEFI mode

Need some Clarification....
1. The OS you are updating from (7 or 8.1)
2. The Current Boot (UEFI secure boot On/Off or Legacy)
3. Sata Operation mode in BIOS (AHCI or anything else)

If running win8 or 8.1, no changes are needed to be made in BIOS while updating
If running 7 thing go a bot trickier..

Hi,
I recently bought a hp pavilion 15 au038ca model. It came with a lot of bloatware so I decided to clean install Windows10. I used Windows Key Finder software to find my key since it's embedded in the bios, wrote it down and went ahead to install the same version as my previous windows: Windows 10 home x64.
Before I even started with the installation, I could not see my device in the boot options( I was using a bootable usb drive). So I went to the bios and enabled legacy support and when I switched my laptop back on into boot device options, there it was: a usb drive option. So i selected it and went on ahead to do a clean install of windows. Now the problem is, whenever I load up system defaults in bios and save it, my laptop does not boot into windows. It gives me this error:

Boot device not found.

Please install an operating system on your hard disk.

Hard Disk - (3F0)

...But as soon as I enable Legacy mode, it boots up into windows. My question is, how do I install windows into uefi mode and not legacy mode? Because I read many articles saying that uefi equals faster boot times and has more advantages than the older legacy mode. And whenever i try making a bootable uefi disk, there is still no device options when only the uefi mode is on. But when the legacy mode is on, then I can see my disk under the boot device options.
Second question, how do I change my hard disk partition to gpt from mbr?
Thank you

Hello,

I bought new laptop (HP 250 G5) few days ago and it came without system on it so I tried to install Windows 10 from bootable DVD. I have both UEFI and Legacy modes enabled in BIOS.

When I try to boot from my Interna CD/DVD ROM Drive i just get some yellow screen and nothing happens.
I tried disabling Legacy Support but then I have no boot devices in UEFI mode.

Here's my BIOS setup:
Is it possible at all to boot Windows 10 from DVD in UEFI mode and am I doing something wrong?

Answer:Windows 10 installation from DVD in UEFI BIOS mode

You can`t have both enabled at the same time.

If you try UEFI, boot from the dvd drive, there should be 2 listings, your normal dvd and your UEFI dvd, just choose UEFI dvd.

If the disc doesn`t show up for either choice then you have a bad disc.

Hi All,

I bought a new Acer V5-572 Laptop which came pre-installed with Linux and BIOS was UEFI mode selected. To install windows 8.1, I made a installable USB of windows 8.1 and selected Legacy boot in BIOS to boot from it. While installing I formatted the harddisk completely using DISKPART "clean" command. Finally, Windows 8.1 got installed on Legacy boot mode.

But now when I changed the boot mode from Legacy to UEFI, it doesnt boot from anything(not even from same USB) and gives error i.e no bootable device.
I tried ALT+F10 for going to Acer Factory setting, even that doesnt work. May be I have formatted System Recovery/Factory settings partition as well.
Can anybody help me here to boot from Windows - USB on UEFI mode ?

Thanks
Nitin

Answer:Windows 8 installation issue with UEFI Bios mode

I suppose my first question would be why would you want to install Windows 8 as Legacy?

If you have a Bootable Windows 8 flash drive, you need to use the Boot Device Menu and select the UEFI version of that device to boot into the UEFI configuration. The bios has to be set to allow for UEFI devices and the flash drive has to be formatted in the FAT32 configuration.

It won't boot anything as UEFI because you do not have a UEFI configured install of Windows 8.. or Linux.

On Toshiba notebooks where UEFI BIOS is available, it?s necessary to disable secure boot and to change the boot mode to CSM in order to boot from external sources and to install other systems than Win 8 or Win 8.1

Some workarounds in the internet describes the installation of Windows 7 in UEFI mode but I doubt this will be possible on Toshiba notebooks since the BIOS is different and modified for each notebook series.

I am not sure if this subforum is the right place, if not, pleases help me transfer to the right forum...

I recently just build a new setup with Asus P8Z77-V LK, this motherboard comes with UEFI boot and legacy BIOS boot support.

So I tested install windows 7 in both mode, and I didn't find any advantage of UEFI consider it is a new technology been promoted quite a lot for recent years.

The benefit I found is: a graphic BIOS setup, which is useless to most users if you don't OC. Even you did, I still find using keyboard to navigate through the menu is much easier than mouse.

Faster boot time? very negligible, could be 31 seconds compare to 28 seconds. As I timed use my stopwatch, the value could include a few seconds human error as well.

Support boot from > 2.2TB HDD? nowadays most user use SSD as boot drive so this really doesn't matter.

GPT disk partition? don't see any benefit here compare to legacy MBR...

Anyone can enlighten me what is the advantage of UEFI here?

Thanks a lot!

Answer:What's the benefit of UEFI and install Windows in UEFI mode?

Thanks for adding information about EFI BIOS which present a problem for many during installation and repairs.

For this reason alone, I would advise disabling EFI BIOS in BIOS boot order or choosing Legacy BIOS in BIOS setup, installing normally to an MBR disk.

Wiping a HD already formatted as GPT disk with Diskpart Clean Command can clear the way for it to install as MBR. Sometimes it also takes runnning the command "Convert MBR" to change disk from GPT.

Hi everyone,

I'm attemping to install Windows 7 64 bits in a Sony vaio SVE14A25CLB laptop. Many threads in this forum already help me a lot to change the UEFI settings to boot from a DVD or USB device in UEFI mode and I clean the hard drive with diskpart. Also secure boot is disabled.

My next opponent in this journey is while windows setup is loading the files, on UEFI mode, it just stop at loading the disk.sys file (checked in safe mode), but in Legacy mode (BIOS) the windows setup (DVD or USB) start without issues (this is how I managed use diskpart).

I don't think it could be due to hard drive or memory issues (I didn't run any tests yet), as the windows setup start normaly on Legacy mode and It install successfully Windows 7 on a MBR partition.

Make sure you have followed Option One in UEFI Bootable USB Flash Drive - Create in Windows
to create the flash stick.

To install Win7 in UEFI mode sometimes requires some level of CSM or Legacy set in BIOS, even "Boot UEFI First." You will need to scour those listings, post back camera snaps of all available choices for UEFI, Legacy, CSM, and boot order. Are you choosing UEFI device to boot. That would point to the media being the problem.

At Eight Forums they can help you derive your Product Key so that you can reinstall 8 to an MBR disk using media they should also be able to link you to. This is providing the BIOS won't auto-activate on MBR. These mysteries are all shrouded in EightForums which I will get over to one day when Win7 stops being the most popular OS and keeping us so busy here.

Sometime in the fall I started getting Windows 10 update errors trying to install 1607 (the anniversary update I believe). After trying different fixes I just ignored it for a while hoping windows would come up with a fix. 6 months later and I'd like to finally resolved this issue once and for all.

Windows Update Failure

I found I can use msinfo32 from the cmd shell to see my BIOS Mode which indicates I'm in UEFI
So I'm not entirely sure what the problem is. I did some funky things when I first built and installed Windows on this computer about a year ago. I have a 3TB Hard Drive and a 500GB SSD. And I found out I wasn't able to use all 3TB without using a GPT. Found some guide online followed the steps and fixed that issue.

I think there was an issue after that where the 3TB hard drive had the Boot part on it, and I followed some other guide to get my SSD to be the boot drive. But I think what I did then has put something in a weird state thats causing the update issue above.

Heres the Partitions
And heres using diskpart
Looking at other peoples partitions when using UEFI and GPT they have some partitions I don't have. Like MSR, System, Recovery etc... but mine just has the one single Primary partition. Recommended UEFI-Based Disk-Partition Configurations What I also find weird is that my boot partition is Disk 1 instead of Disk 0. If I unplug the HDD and boot the computer, then the SSD becomes Drive 0 but the update still fails.

Is there any way to install windows 7 32 bit on Asus T100T? In T100T there is only 32-bit UEFI and it cannot be changed on legacy BIOS. Win 7 32-bit does not support UEFI (why not?) but is there someway to bypass that i.e. would it work with some 3rd party
bootloader or something like that?

Answer:Windows 7 32-bit UEFI installation

The reason why it wasn't supported in Win7 is due to an incorrect market forcast. Initially, when UEFI 2.3.1 spec was worked on and brought to the desktop, 32bit OSes were thought to have been eliminated from the market. If you recall a long time ago, the
rumors of Windows 8 were it would only come in a 64 and 128bit versions and no 32bit. As such, the strategy was to eliminate it, and it started with UEFI support in Vista SP1 x64 but not 32. The same continued on with Windows 7 releases. However, it was obvious
that 32bit was still very important and that no one would be buying a 128bit OS, so Windows 8 x86 was made to support UEFI.
Now down to technical things, it is the bootloader of Windows 7 that has the most problem. I have had limited problems with other interfaces, such as WMI returning garbage.
Using setup isn't going to work out because it may detect the firmware's capabilities and convert the disk to GPT. The key to have Win7 x86 boot on a UEFI board is to not use the System Reserved partition. This means you would have to run diskpart to format
the disk, and then using DISM to apply the image. NOTE: I have not attempted to deploy the OS on that particular hardware and BIOS version. It may still have issues or not able to boot.

Hi I'm new to eight forums, I hope i can become a valued member soon.

I purchased a laptop in Korea not long ago, i came with the option of Win7 or 8 but i chose to get it without an OS because I didnt want an OS in hangul. I installed Windows 7 on it and I've been using it fine ever since. Now I have decided to move on to Windows 8. And since my laptop has UEFI capabilities I might as well go all out.

But, I want to make sure I do it properly and I would like to understand a few things first.
In my bios I have the following settings (I'm only listing the things that would have something to do with UEFI or things I have no idea about.

HDC Configure As - I have no idea what this is either and it's set to AHCI. Other option is IDE.

VT Suport - Whatever it is its enabled.

Boot Type - Set to Dual Boot Type - I guess I will change that to UEFI when I go to install Windows 8.

Hey all,

I bought a new Toshiba L70-BST2NX1 laptop and I am trying to install Windows 7 (Home Premium 64-bit) on it using UEFI method, not dual boot with Windows 8.1, just Windows 7 all by itself. I got stuck early in the installation process.

Here is what I did: Disabled Secure Boot in UEFI setup
Removed all partitions from HDD
Began booting from Windows 7 DVD while UEFI is enabled

Having done that, on the screen I see "loading files" text and a white horizontal progress bar. Then the animated Windows startup logo appears with "Starting Windows" text, but then it freezes in the middle of the logo animation. This is where I am stuck.

I certainly want help getting me through the installation but I also have a number of questions. Does Windows 7 normally support this type of UEFI installation?
If UEFI booting is disabled (CSM) on UEFI-capable machine, what functionality do I give up?
If Windows 7 installation is performed with UEFI boot disabled (CSM), can UEFI booting be enabled again after the installation process is finished?

These are the instructions that Toshiba has, and they say to use CSM booting, but does that mean that UEFI Windows 7 is impossible on UEFI-capable Toshiba machines?

Hello,

A while ago my boss told me I needed a laptop, so I bought a nice second hand one, and bought a fresh new copy of Win7 SP1. It always worked fine, until the laptop died.
My boss bought me a nice new laptop, but we found out that some programs don't run well on Win10. We also have an outdated server setup, and Win10 seems to have some problems with it.

So we decided that I need to go back to Win7 64bit. And I decided to start reading up on that UEFI thing. I double checked that my Acer E5-721 has UEFI activated.

Via the tutorials on this forum I found out that I need a UEFI compatible ISO from Windows. The one I have is not. Apparantly I need BOOTx64.EFI in the EFI folder. Which I don't have.

So I unpacked the ISO, and unpacked INSTALL.WIM to find the BOOTMFGR.EFI file, and copied it to the EFI folder. I then used IMGBURN to turn it all back into an ISO and Rufuc to create me a bootable USB.

But it just don't work. I don't get the Win7 install screen. The laptop either goes to Win10 or gives me a screen that says: "Windows failed to start. A recent hardware or software change might be the cause. Status: 0xc000000f."

I also tried to put the required EFI files into the BOOT folder (seeing as some tutorial I found via Google suggested it). But nothing seems to work.

Can somebody help me to fix this??

I was reading about a build where a guy was getting 9 second boot times with a Z97 and Plextor M6e. He said he had to do a Windows GPT ( UEFI ) installation... What is that and how do I do one?
 

Answer:Can someone explain Windows GPT ( UEFI ) installation?

You need your motherboard set for UEFI boot. You need your SSD set as a GPT drive (not MBR), and I don't think this can be done during the installation of Windows, the drive would need to be formatted as GPT previously. I don't think there is any way of converting a MBR drive to GPT either without destroying the data. Installation needs to be done from either a disc or a FAT32 drive with the necessary UEFI files, should be included automatically with Windows 8. You need a GOP-compatible GPU. And you need Windows 8/8.1.

Your sig system should be completely UEFI fast boot compliant. If your SSD is already set up as a GPT drive, and you're running Windows 8/8.1, all you would need to do is go into your bios, set UEFI as your only boot method (no legacy), and enable GOP UEFI Fast Boot (or something termed similar to that). This will by default enable SecureBoot as well, which would be problematic if you dual boot.

Hello!

I have my laptop since last december (less than a year), and for unknown reasons, I got a BSOD a few weeks ago and none of the available recovery tools managed to bring me back to my desktop; not even a refresh. That's when I promised myself that I would never ever again install a Microsoft OS, and went for Ubuntu 16.04 (which was already there on another partition). Now I'm realizing that I need some softwares that work best on Windows and not through a VM (eventhough I already have Windows 10 running in VM for Microsoft Office).

So here's my issue:

I created my bootable Windows 10 installation USB but I can't boot from it! I doesn't even show as an option. Ubuntu does. I tried a USB 3.0, 2.0, UEFI, Legacy, MBR, GPT... Nothing seems to work. Searched forums for hours and couldn't find a solution.

Now for grub to be able to launch at startup, I had to add an efi file to the trusted uefi file list in the BIOS. I was wondering if such a file should be added to be able to boot from my USB... (secure boot is disabled).

I want to keep my Ubuntu and Kali...

I've attached a screenshot of my ssd partitions.

Any idea?

Answer:Can't boot Windows 10 installation from USB - UEFI

How did you make the Windows 10 USB flash drive? It needs to be formatted as FAT32 and the partition on it marked as active to be compatible with both UEFI and legacy BIOS (or CSM). Once it is formatted as FAT32 and the partition marked as active, then you just copy the files and folders from the mounted Windows 10 ISO over to it.

As you can see from my topic subject, my W520 laptop won't boot from my Windows 7 Installation DVD when it is set to UEFI-only mode. I don't get any errors or anything, the screen just goes black for a second and returns to the Boot Menu, when I select the DVD drive. For what it's worth, my hard drive is already GPT partitioned, and I need to repair the installation. Before I ask for help, I just want to mention that I created this particular Windows 7 Installation DVD using the All-in-One tutorial so that I could have 32-bit and 64-bit options all on the same disc. The disc booted fine in "Legacy/UEFI" boot mode, so I'm not sure what the problem is. Does anyone have insight into this? EDIT: I've been following this tutorial: http://www.insanelymac.com/forum/index.php?showtopic=186440 and am at Step 14.

Is it possible to install new Windows 10 UEFI on Samsung 850 EVO and boot without Windows Boot Manager, I mean to install without that option in BIOS.

Answer:Windows 10 UEFI Installation Questions

Windows Boot Manager is the UEFI booting mode for Windows 10. Look at your disk management screen and you will see an EFI System Partition - that is UEFI and contains the Windows Boot Manager.

If your Windows 10 is installed and booting in legacy BIOS mode, in disk management you will see a System Reserved partition marked as active as the System Partition.

The example screenshot here:
Disk Management - How to Post a Screenshot of - Windows 10 Forums

shows a legacy BIOS setup, evidence by the first partition which is labeled as a System Reserved partition, marked as the active system partition.

This is a computer booting in UEFI:


because the second partition on Disk 0 is shown as an EFI system partition. Ignore Disk 1, even though it has an active partition it is for data only and does not boot the computer.

Answer:HDD not detected during Windows 8 installation in UEFI

You can't see the HDD, because your HDD is MBR style when you installed Win7 in legacy mode. But when using
UEFI you must use a GPT style disk.

At the beginning of the setup press SHIFT+F10 to open the command prompt. Run DISKPART, select the DISK and delete all partitions on it. Exit DISKPART, close the CMD and continue the Setup. Now you should see it."A programmer is just a tool which converts caffeine into code"

If I select to start the install from normal option it start to install withou UEFI.

I have burn the iso to a USB PEN and if select the the UEFI option It shows the option from starting the UEFI boot.

There is no problem at all in making two partitions before you install Windows. Just be sure and make what will be your C: big enough to hold Windows (30 GB) and any other programs that you will put on it. You can then put all of your Documents, Pictures etc on the D: drive.

But after I tried switch to UEFI and do UEFI installation, every time it start loading installation files and after that windows freez on "Starting Windows" screen.

I've got two peaces of these ultrabooks and they do the same.

I used Flash disk, USB CD-ROM, two different versions of windows 7, but it have same ending...

Answer:Satellite M50D-A-10L - Windows 7 UEFI installation

I?ve got a Satellite M50-A model (its similar to the M50D-A but it was equipped with nVidia GPU instead of ATI GPU) and could install the Win 7 switching the boot mode to CSM mode.

Generally speaking the UEFI boot mode can be used only for UEFI capable system like Win 8 or Win 8.1 and some Linux distributions.
Win 7 isn?t UEFI capable system.

However, there are different workarounds to install Win 7 64bit (not 32bit) in UEFI using the GUID ? partitionstable (GPT). Only Win 7 64bit contains the UEFI boot loader.

But very important fact is that UEFI installation isn?t available (by default) booting from USB memory stick due to missing uefi boot loader! In case you use the USB memory stick for installation, you have to add the UEFI boot menu? (search in google for more details).

Last but not least everything depends on BIOS support? in case the BIOS would allow the installation only in CSM mode; all these workarounds would be useless.

Hello all. My first post on these forums. Hope I don't break any rules in it
I'll try to be short and clear in describing my problem, but please bare with me here as it's not the simplest of issues (not to me anyway).
I got a (at the time new) MSi laptop several months back with just a regular Windows 8 Core x64 on it and a UEFI boot system (or whatever is the name for "BIOSs"). At some point I had problems with the settings - I couldn't open any of my computer's settings - and I researched long and hard to no avail. So I installed Windows 7 32-bit (the only disk I had). Now, I'm trying to upgrade to Windows 8.1 Pro. I noticed that after the installation of 8.1 Pro my system was still running in 32-bit, so I made a bootable USB stick with the retail version of Windows 8 Core with no key just to get the system back to x64. It worked just fine. I cannot, however, boot in UEFI mode. I believe the partition got wiped somewhere in the Windows 7 installation. Whenever I enter UEFI by pressing the DEL button (I cannot see the UEFI firmware settings tile under the Troubleshoot option) I see the boot mode is LEGACY and when I change it to UEFI, save and reset, it doesn't boot, giving me a "No media found" error. I don't care about my settings/files as long as I get UEFI back with Windows 8.1 Pro running.
I googled long enough to know I'm not going anywhere if I don't ask someone with expertise on this matter.

I own a family 3-pack of Win7 Home Premium. I have installed this OS 6 or 7 times using the 3-pack product key (only 3 PCs ever have it running - old PCs get retired and new PCs get a clean install).

Activation has always gone as expected. The first 3 times were very easy over the internet. The next few times it required a call.

The last 2 installations were made on new systems with UEFI BIOS. I installed using an EFI ready USB stick and in UEFI mode at boot.

The Activation on these two installs was convoluted.

First, trying to activate over the internet returns an error message that basically says I can't use upgrade media to do a clean install. (This message has never appeared before that I recall).

Then, once that method has failed I do not get any option to use telephone activation. I have to type in option 4 in a slui.exe run to get the phone number.

Normal telephone activation does not go as usual. The installation string does not work (as normal), but I eventually get to the operator. But the operator cannot generate a validation key as usually happens.

The operator then checks to see if my product key is valid (it is), then sends me off to an Activation Technician.

The tech then needs to take remote control of my desktop. He tries everything I have already done (same results), then tries typing in an override code (that fails), then after some time finally comes back and types in a new Activation Key in the nine boxes. It takes a restart, and a new override ... Read more

Answer:Does a UEFI Installation affect Windows Activation?

This is perfectly normal
The Family Pack Keys are UPGRADES - and theoretically require a pre-existing installation of an activated Windows before allowing the install.
In fact, Windows will allow an installation without the prior one - BUT there is a tag which tells the Activation request that the machine was Clean-installed. This in combination with the Upgrade Key is what leads to the failure to activate.

There are at least three workarounds to this - the ONLY one which MS support is the double-install method.

Hey guys, I've never seen a full guide to installing Windows 7 in UEFI mode before anywhere, trust me I've looked. But I managed to pull it off a few days ago. So I thought I'd share it with you guys

What you'll need:
A Windows 7 64 bit ISO (doesn't matter what edition and can be an All in One disk.)
Virtual Clone Drive (To Extract ISO Contents)
8GB+ USB Stick
A UEFI BIOS
7-Zip
A Computer already running Windows

Steps:
1) Install Virtual Clone Drive Link Here and also install 7 zip Link here

2) Make a flat copy of your windows 7 x64 ISO, which mean just extract the contents of the ISO into a folder. First you'll want to mount the Disk Image, by right clicking and mount to Drive E: for example.
Mounting Image Example

Next open the disk drive you mounted it to, and copy the contents to a place you'll remember. (This will take a while)
When it's done it should look something like this

3) Format your USB Stick.
Just go to computer, right click it and press format. Make sure you change file system to FAT32. This is so you can boot from it.
Settings for formatting

4) Now here's the hard part. Preparing the flat copy for UEFI.

Go to the EFI folder, make a new folder in there called "boot".
Now go into the "Microsoft" folder which is in the EFI foler. Then boot, and copy the contents.
What it should look like
Put that into your boot folder you just made.

Now that's done. Go to the Sources folder which is in the root Here!

Hello, I recently bought a Lenovo X1 Carbon and, after an brief excursion into Windows 8, decided to install a clean Windows 7 on the computer. I had successfully installed Windows 8 in UEFI BIOS mode without CSM compatibility (and secure boot). Today, I have tried to install Windows 7 with UEFI BIOS mode without CSM compatibility and without secure boot. When I tried to load the Windows 7 (SP1 slipstreamed) setup from a bootable FAT32 USB stick, the "grey bar" initialisation worked fine (i.e. the data is read), but the setup hung on "starting windows" (tried 3 times); I tried one of the safe modes and the system stops reporting loaded system files at "classpnp.sys". I then went back to the BIOS and enabled CSM compatibility (still UEFI only). With this setting, I couId install Windows 7 without any problems, and I installed it onto a GPT partition. After the installation I installed all drivers and Windows 7 updates on offer and also updated the X1 Carbon drivers through Lenovo System Update. Then I tried to disable CSM and reboot, which again resulted in the system getting stuck at "Starting Windows" like during the installation attempt. Have any of you successfully installed Windows 7 with UEFI only and without CSM enabled? Are there any "tricks" that can be applied to get this to work? N.B. the only benefit that I expect from getting this to work is the "nicer looking" UEFI "BIOS" screen. BIOS version is 2.03.

Then I created a copy of all files on a 8gb SD card, used bootsect /nt60 x:, again, no UEFI boot option available. My last try was, because I have no USB pen, creating a fat32 partition on one of my usb hdds, again copied all files on it, did a bootsect /nt60 x:, and now I was able to chose UEFI: ... from the boot menu.

So I booted from it, but then it gave me this error screen, and I don't know why, or what to do now anymore. Any help would be really appreciated.

So, what is that basically ? When i boot from my usb stick, i have the option to install in UEFI mode and in normal mode.

I know in UEFI mode it makes 4 partitions, and in normal mode just 2 partitions.

So basically if i install in UEFI mode i will have better windows 8 implementation and it will boot and post and run faster ?

What are the advantages for installing in UEFI mode vs normal mode ?

And why in UEFI mode the OS creates 3 additional partitions, instead of only one ?

Answer:I cant install windows 10 in uefi mode

1001fboy When you install in UEFI mode, the installer expects to see a drive that has been formatted in GPT mode, not MBR. So, you need to confirm that your drive is formatted in GPT mode. You probably also need to disable Secure Boot in the UEFI menu. Good Luck========================================================================I am a volunteer and I do not work for, nor do I represent, HP.---------------------------------------------------------------If my posts helped you, please click the Thumbs-Up symbol on my post to say thanks.If my posts solved your problem please click "Accept As Solution".========================================================================

Hi there,
I wanted to boot an existing Windows 10 install taken from a UEFI notebook into an older non-UEFI notebook and I only get a flashing cursor. Booted with an installation media and the automatic startup repair did not work.
Browsing online I tried re-creating the boot sector but in the end I understand that to do so I need to attempt the fix from a UEFI system.

I perfectly understand that a Windows installation should not be moved to a different system but I was hoping to manage to boot it up to save some files. Alternatively, I can plug the HDD into another PC.

Is there anybody aware of a way to make this installation work?
Thanks
Tony

Answer:UEFI installation on non-UEFI system

The main problem is that you will have to convert the drive from GPT style partitioning to MBR partitioning so that you can mark a partition as active to be able to boot from it in legacy BIOS. The easiest way to do that is to create an image of your Windows and any data partitions using a program like Macrium Reflect Free, then convert the drive to MBR, then restore the partitions back and create your boot files required to boot in legacy mode.

Alternatively, you can copy the partitions to a second HDD/SSD partitioned as MBR, create the boot files on it, and then install that in the legacy BIOS computer.

Machine: IdeaPad N581 with latest BIOS/UEFI (v9.01). OS: Windows Hello!  I'm trying to install Windows 7 Pro (64 bit) on my machine, which is currently running Windows 8.1. I want a clean install, i. e. wipe out the whole HDD (partition and format). Booting from DVD, the installation fails after the setup DVD has been loaded and the display says "Windows is starting" (the installation). There's a short graphical glitch an then a frozen display with the loading screen.  When I switch from UEFI to legacy BIOS, the installation starts as normal. But I want Win 7 to run on UEFI.  Is it possible, that the latest UEFI version does not support Windows 7? I had Windows 7 on UEFI before I made an BIOS update one year ago.  I made several DVDs to check, whether it's a faulty disc. My questions:  1) Where can I get an older BIOS/UEFI version for my machine (download archives?)?2) What else might keep Windows 7 from being installed under UEFI?

Answer:Windows 7 installation fails after UEFI/BIOS update

Hello and welcome,
 
Try enabling CSM support in BIOS.  Should be somewhere near the UEFI/legacy option if it's available.  Win 7 won't run in UEFI mode without CSM.

Hi

I have a laptop with windows 8.1 pro x64 but i never was comfortable with windows 8.1 or 8. I am more comfortable with windows 7 but the problem is that this is a UEFI laptop with secure boot enabled and obviously partitions must be GPT (not sure).

I deleted all the partitions by taking out the drive from machine, attaching it with my desktop system (windows XP) and used EaseUS partition manager to delete all the partition table and made simple partition style of 1 primary and 3 extended logical drives. (It also deleted the recovery and system reserved partitions).
My C drive is 50GB now.
For installing windows 7, i did some settings in BIOS:

Secure boot - disabled
boot type - legacy boot type (other options are UEFI boot type and dual boot type)
Intel rapid start - disabled
Intel rapid storage - disabled
Intel anti-theft - disabled
AHCI type - SATA (other option is RAID)

However my question is something else. If i want to install windows 7 in UEFI mode, i know i have to use RUFUS to make it UEFI bootable and install it. BUT i want to know something:

1. For installing Windows 7 in UEFI, DO THE PARTITIONS need to be in GPT mode?

Because as far i THINK now that i made partitions again so it must be in BIOS mode and not the GPT mode. Am i right?

2. Installing OS still, WITHOUT UEFI (disabled UEFI boot from BIOS) and partitions in BIOS mode, will the OS windows 7 function normal or not?

Answer:Windows 7 installation on UEFI computer, URGENT help needed.

1 Yes,they have to be GPT.Otherwise,you may render your system unbootable in UEFI mode.

2.Windows 7 will function normally,but you won't get the advantages UEFI has. If you want them,boot from the USB in UEFI mode,set Boot Mode in UEFI and install Windows 7 normally.

If you encounter any problem,let us know as soon as possible.

Is it advisable to set the UEFI BIOS (Asus ROG Hero Maximus VI motherboard) to a factory default settings before installing Windows 10? Or should I at least set the memory "XMP" profile?

Thanks!

Answer:UEFI BIOS settings to prepare for Windows 10 Installation

Hello Greg,

The only UEFI firmware settings that I would recommend to temporarily change until Windows 10 installation is complete is:

Disable Fast Boot to make it easier to be able to boot from a USB. When Fast Boot is enabled, you don't have time to be able to press the Boot Menu key to select to boot from a USB.

Disable Secure Boot. Some motherboards do not support booting from a USB while secure boot is enabled.

I'm struggling to install windows 8 in UEFI mode on my asus p8z77-v lk motherboard.

I updated the BIOS to the latest version, that is 0908.

I have this USB stick that was created with that Windows 8 USB tool, it has the Windows 8 installer.

I can't seem to boot into the USB stick in UEFI mode.

Do I have to disable CSM (compatibility support module)?

I'm trying to google this but it is just confusing me even more..........

Did the USB have to be created in UEFI mode? :|

Answer:installing windows 8 in UEFI mode on p8z77

I do not have an answer for you but I can share my experience.

UEFI via USB did not work for me in Consumer Preview (using microsfot win7 iso to usb).

It DID work with the $40 upgrade using windows upgrade assistant to make USB stick.

My ASUS boards use UEFI perfectly. Gigabyte tends suck at UEFI implementation. On my p67a-ud7-b3 I had to disable the gsata (gigabyte sata) to get UEFI to work properly.

I can suggestion 3 things.
1. Burn an ISO to DVD and try UEFI install that way.

2. Make sure your board is properly booting UEFI, try a ubuntu or redhat disk just to see if it boots UEFI.

3. Check to see if you have something like gsata enabled that could be disabling UEFI boot.

Hello Guys,

recently i purchased a new laptop that came with win10.

The laptop is Lenovo z50-70

Unfortunately my brother managed to download so many viruses, that I decided to do clean Win 10 install. I had no important data on the laptop and I thought it would be the easiest solution.

So I inserted Win 10 dvd that I got with the laptop into the drive and went on with the process. Decided to not keep any data, formatted the drive, and when I needed to choose where I want windows installed, it told me it cannot be installed on GPT Style partition, which I found weird, because Windows was installed there before.

The partitions look currently like this:

https://i.imgur.com/SqMbqdo.jpg

So I did some reading and found out that I should boot in UEFI mode so that I can use the GPT style partition, however when I wanted to boot from DVD using the UEFI, it wouldnt work.

Using these boot settings:

I got this result

Answer:Windows 10 cant be installed on GPT - Cant boot dvd in UEFI mode

Hi, Thanks for all the info. Some basic questions:
1. As it's a new laptop, could you not have used the manufacturer's recovery partition to restore it to 'as bought'? Or was it bought without an OS installed?
2. Are you sure the DVD that came with it is actually a Win 10 install DVD, and not something else?

3. If you wish to clean install, suggest you get a Win 10 DVD or bootable disk thus, making sure the language is appropriate:
https://www.tenforums.com/tutorials/...-download.html

4. Win 10 needs to be installed to unallocated space. For this reason and to ensure removal of all nasty things you don't want, you should delete all existing partitions (other than any manufacturer's recovery partition, although that no longer seems to exist if it ever did).

Finally to make things easier in the future, disk imaging is very strongly and repeatedly recommended here. E.g. Macrium Reflect (free) + its boot medium + external storage for images. That was you can restore a non-bootable/not working PC to a previously working state fairly quickly without technical help (barring hardware failure other than the drive).

Note - a better way to post screenshots is to use the icon to the left of the video icon above your post 'Insert image'.

Hello

Since UEFI exists, some people talk about BIOS replacement by UEFI in short-term (2011 for exemple) (see "News").

Who never has problem with BIOS bugs ? I must fight against several problems on one of my mobos because of its incorrect BIOS code, essentially for long time boot BIOS and very buggy S3 sleep mode.

However, when I read many posts about people who have installed their Windows 7 x64 in UEFI mode, I'm afraid of some new problems that UEFI causes, according to these people, even during a Windows session, even if installation was fine.

I would like to know your experience about UEFI, on motherboards which support it (my motherboard is an Intel DG45ID which proposes UEFI boot).

Thanks

Answer:Is it right time to install Windows 7 x64 in UEFI mode ?

I think most cost effective motherboards are still BIOS/MBR. I haven't really looked hard but I haven't seen any UEFI motherboards readily available where I am. I'd only jump to UEFI at this stage if I needed > the 2TB limit. 1TB at a time is big enough for me to backup. If the BIOS is playing up can't you flash it to a later version?

Hi there. I've built a new HTPC. I'm trying to install Windows 7 Ultimate x64 on my HDD using the latest version of Rufus to make a bootable USB drive. I've realised that I have UEFI BIOS now, so I've searched for tutorials on how to setup Windows 7 using UEFI and a USB drive. I've disabled Secure Boot and Fast Boot in the UEFI BIOS. I've made bootable USB drive using GPT partition scheme for UEFI, FAT32 file system and default cluster size. The UEFI BIOS shows my UEFI USB drive and boots. But then, after "Windows is loading files" window, setup ends up with a blue screen. I have only one HDD and it's not empty. It has Windows 7 Ultimate x86 installed that I use on my old system and I'm forced to use for now.

Also,

I have 1TB MBR HDD and installed Windows 7-32bit in BIOS mode.

Currently, I have to go to bios setting every time and change boot priority manually in order to boot from another windows. Is there any way to use Windows Boot Manager (dual boot) instead of selecting manually from mainboard setting?

Answer:Two Windows on Two different mode (Bios & UEFI) How to dual boot?

Other then reinstalling W7 in UEFI to a GPT drive, or reinstalling 10 in Legacy mode to a MBR disk, then no.

You`ll have to keep switching, you are going to have to choose a bios method and stick with it if you want a true simple dual boot.

I would consider the way you`re doing it a real hassle and wouldn`t think twice about fixing it correctly.

Hello, So, long story about Windows, the BIOS and my Lenovo. So, I got my ThinkCentre Edge 72 in December 2013, and originally it came with NO OPERATING SYSTEM. So what I did was got a Windows 7 Ultimate SP1 installation on it. But, it was 32 bit -_- Ok, so I upgraded it to Windows 10 on launch day. No issues with drivers whatsoever. But if I check my System Information it says my BIOS mode is legacy. http://i.imgur.com/eZ6k8iu.png So I wanted to boot my Windows 10 in UEFI mode. So I go to the BIOS and change it to UEFI, it says no operating system found!!!!! One of the reasons I want UEFI is that I don't want to see the blue windows logo while the thing is booting, I would like the Lenovo logo with the spinning thing. I know that sounds stupid, but it's my preference. But then I realised it's because I have 32 bit. So my question is can I boot 32 bit Windows 10 in UEFI? Another thing is, my Windows 10 RAM says 3.33 GB usable out of my 4 GB. If I install 64 bit can I use the whole 4 GB?Thanks a lot for your help.

Okay, so the other week i received a new Clevo P650SE laptop. The laptop only had a 500GB 7200RPM HDD with Windows 10 to begin with, so yesterday i added my Samsung 840 EVO SSD. As i wanted this to now be the primary drive, i made another new installation of Windows onto here. After doing this, the system now displayed a boot selection at startup with the choice between the new Windows 10 installation on my SSD or the old one on the HDD.

As i no longer wanted to use the HDD for running Windows, i decided it would be best to delete Windows from this drive. So i booted onto an Ubuntu USB and wiped the entire drive of it's data in GParted, which included three different partitions. This seemed perfectly fine to me at the time, because i had a the new installation from the SSD showing up in the boot manager.

However, when i rebooted the machine and attempted to boot into the new installation on the SSD, it gives me this message:

"The boot configuration data from your PC is missing or contains errors.
File: /EFI/Microsoft/Boot/BC Error code: 0xc000000f"

I have tried everything to recover the system but nothing has worked. Startup repair from my Windows USB doesn't do anything, the system reset wouldn't operate because it stated that the partition was locked.

Hello!

I own a Samsung R780 notebook with 08JA bios version, which has the UEFI Boot setting. The laptop comes with Windows 7 which I upgraded to Windows 8, but it was installed in BIOS mode, and I wanted to switch to UEFI. I tried to follow the instructions on the following website: Converting Windows BIOS installation to UEFI - TechNet Articles - United States (English) - TechNet Wiki

Unfortunately, after I followed all the steps, Windows didn't boot anymore, and it reacted like nothing was installed. Because of this, I wanted to do a clean install. After I booted in UEFI mode from the DVD, the Windows 8 logo appeared and before the very first menu appeared (where I select the language, time zone etc) I got a blue screen that disappeared too fast. I tried to record with my video camera and to play it, and found out the error KMODE EXCEPTION NOT HANDLED. I discovered that if I'm trying to start the installation in BIOS mode I don't get the blue screen. I tried to start the setup program in bios mode, and to partition the hard drive by creating one single partition as big as the HDD is, then I cancelled the installation, started the diskpart utility from the command prompt and executed the "clean all" command on the partition.

After all of this I was finally able to boot the DVD in UEFI. I partitioned the HDD how I wanted and when I started the installation I got another blue screen that I needed to record, with the same code as above: KMODE EXCEPTION NOT HANDLED... Read more

Answer:Blue screen when installing Windows 8 in UEFI mode

The article that you refer to seems to be an excellent piece of work - yet it still didn't work for you.

Are you able to reinstall Win7 in UEFI mode? Are you able to wipe/initialize the entire hard drive and then install Win7?
Are you able to install anything after turning Secure Boot off?
I also have seen discussion about the CSM setting needing to be disabled. Here's a link to the UEFI how-to at the Intel site: Microsoft Windows 8? - Enabling Secure Boot

I noted 2 things at the Intel link:
- Intel states that you cannot convert a BIOS install to a UEFI install - as such I have to wonder if the attempt made some changes to your hard drive/partitions that are now preventing the installation (that's why I suggested trying a wipe of the HDD).
- you don't mention having a efi file for your Windows installation (but it's required to install Win8). I have no idea if this is included on the installation DVD or not.

Hi guys

I have searched various places for a solution but not quite getting a complete answer for my problem or perhaps I'm just lacking the understanding.

I have an Acer Aspire s3 391 , preinstalled with windows 8. I used a bootable usb with windows 7 64 bit to try an install windows 7 instead. I initially tried to run the setup from my desktop and somehow I messed up the installation. I can now no longer start windows and get back to my desktop.

I am now trying to reinstall windows 7 again from my bootable usb which I now made using RUFUS from a tutorial on this website.

I have tried using the UEFI Boot mode.

This is my bios when using it




this takes me as far as the windows loading screen

thereafter windows starting and freezes.


I then tried using the Legacy boot mode using another usb made using RUFUS.
My bios was now




After going through the initial installation set up screens, I select custom install, and it his takes me as far as the step where you choose disk partition to install, but there are several disk partitions


and a message says that the main 450GB partition is of GPT style which doesn't allow.


I am unsure how to go about installing windows now, which method to choose, and which disk partitions to use as there are several.

Any advice would be much appreciated. Sorry about the long post just wanted to be absolutely clear!
Thank you

Answer:Installation stuck on Windows Starting screen - UEFI based laptop

Try clicking on the Drive Options (Advanced) to delete all partitions, as fundamental to reinstalling any Windows OS as booting the installer.

I notice when you try UEFI mode there are no UEFI devices listed to boot. Try it again and this time put in the DVD or flash stick formatted only with Option One of UEFI Bootable USB Flash Drive - Create in Windows.

Either way you must delete all partitions using the Drive Options pictured in Steps 7/8 of Clean Install Windows 7 during install to begin, then either create new partitions if you have a scheme in mind (e.g. OS on one, Data on another) or create and format one large OS.

I created bootable USB using this tutorial. http://www.eightforums.com/tutorials/15458-uefi-bootable-usb-flash-drive-create-windows.htmlI would be really grateful if someone have the answer. Thank you for your time.

Hello,
I cannot install windows 8 in BIOS or UEFI mode.

it's getting boot and install only in EFI mode. after trying to reinstall it won't allow me to select the disk partition, as it gave me the error "
Windows 8 cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks." i tried all the given solutions on GOogle. even i cannot recover or refresh using windows 8 environment. many times it gives me BSOD. cannot vonvert to MBR as it says it cannot be done on virtual HDD.
tried many things nothing works, need to install windows 8 after every 1 or 2weeks, many a times my BCD data gets corrupt, and windows wont start. Also tried many things to repair this, but only thing that works is reinstalling windows 8.
That gpt or MBR error was solved by selecting UEFI:CD drive. in boot options by pressing F12 after inserting the disk.

anyone has the solutions for this error??

Answer:Solved: Cannot install windows 8 in UEFI or normal BIOS mode

OK OK OK \..
nobody did try to reply for this one.

got it solved, all that was needed was formatting hard drive completely using windows XP, as it automatically formats to MBR type.

the problem i was facing was hard drive was set to GPT which gave many drive errors, and didn't allow to install windows 8 or 7 as they dont let you format with that POWER as my fav old XP did...

OLD IS GOLD!

Please help! How to boot Windows 10 in UEFI boot in Phoenix SecureCore Tiano BIOS Setup, when I changed the boot mode to UEFI, and the first boot priority is my hard disk. I saved the setting changes and boot it, an error happened and said "Operating System not found." What i will do???

Answer:Can't boot Windows 10 in UEFI mode in Phoenix SecureCore Tiano.

You install Windows while in UEFI mode. Not after. You cannot go changing the mode whenever you like, Windows needs to setup a boot process for UEFI.

I am trying to install Vista 64bit onto my laptop (Acer V5 171) which has Windows 8 preinstalled. I could not find a tutorial on how to make a UEFI USB for Vista so I followed the one for Windows 7: UEFI Bootable USB Flash Drive - Create in Windows

I have disabled secure boot and set the USB drive at the top of the priority boot list. When I come to select the boot devices it only gives me two options: The boot manager (main HDD) and the USB HDD. It does not seem to recognise the USB as a UEFI boot device as shown in the tutorial.

When I do select to boot from the USB the screen says windows is loading files and after the bar has filled it gets stuck on the same screen until I power off.

Does anyone know how to get Vista to install via UEFI USB?

I'm not by the machine right now so if you require any more information I can post it later.

Thanks!

Answer:VIsta 64bit UEFI installation stuck on screen 'windows is loading files'

Did you disable ( CSM)Compatibility Support Module - it should be somewhere in bios settings.

It should then show as something like this:

UEFI:USB-ATAPI DVD

If you have done that - you might need to try plugging it into a different usb port - one on the back of the machine, for example. Lord knows why.

This week, I encountered the following strange problem for which I haven't found a final solution so far, though I have found some bandaids. But having a complete solution -or at least a reason why this problem occurs- would be great:
I have a working installation of Windows 7 Professional x64 in UEFI mode. The main disk, SSD #1, contains the following partitions (using GPT): ESP, MSR, system, data. An additional disk, HD #2, with a single data partition (using MBR) is also attached to the system. With this setup, everything works fine.
Now, after adding another disk, HD #3, to the system -my old system disk (bootable, using MBR, one active primary partition and an extend partition with three logical disks)- Windows will no longer boots completely: The boot process begins, the Windows logo is shown. Then, a message is shown in text mode "Windows is loading files" with a loading bar. After a while the boot process stops and I am dropped into the EFI shell. After removing the offending HD #3, Windows boots normally again.

I tried removing HD #2 and only attaching HD #3 together with SSD #1, but this yielded the same problem. Using SSD #1 by itself works fine though. Booting from a Linux live-cd works without problems. All disks and partitions are found and can be mounted. There, I erased the disk signature from the offending HD #3 and now Windows was able to boot and also found all disks and partitions correctly. But after a reboot the same problem reappeared.

I recently installed a SSD hard drive on my new Dell XPS8700 and installed a fresh copy of Windows 8 using the OS disc provided by dell. After completing hours worth of windows updates and driver updates, i go into bios and switch back to UEFI mode only to get a bios error when booting.

The error message that displays is:

No boot device available. Strike the f1 key to reboot, f2 to run the setup utility.
Sata 0: Installed
Sata 1: Installed
Sata 2: Installed
Sata 3: None
Sata 4: None
Msata: None

I booted into the Windows 8 OS Disc and formatted the second hard drive and about 3-4 partitions it had using the "repair disc" tools provided in the OS Installation options. Also formatted while in windows 8 as a simple drive in NTFS with a drive letter.

I found something else on the internet that mentions using bootrec.exe tool. I've tried the scanos, fixmbr, and fixboot options; even though it says it completed successfully, it did nothing whatsoever. The /scanos detects no installation.

I'm still getting the error and the only way around it is switching to legacy mode. Does anyone know a way to fix this issue without having to reinstall the OS in UEFI mode?

Answer:Issue loading in UEFI mode after setting up Windows 8 on SSD on Dell XPS 8700

I ended up reinstalling Windows 8 from the disc. Apparently with Dell, when booting off the OS disc in UEFI mode, the dell logo appears and it pretty much freezes there for a few minutes til it loads Windows 8 installation process. This, I accidentally found out after having to get off the computer right when the dell logo appeared on my screen after selecting option to load off boot disc. Figures. None of the dell techs told me it would take a few minutes either. Either ways, I'm going to run hardware tests afterwards to make sure there is nothing wrong with any of my parts after windows update is complete.

Hi, with the latest bios (either 1.37a (for Windows 8 Beta Driver test (June 2012) or 1.39 (Current) of the W520 and final release of Windows 8 Pro (Build 9200) BitLocker comes up with "Element not found" when trying to activate for the system drive in UEFI only mode. In a new legacy only mode installation BitLocker works fine. In both cases all devices in device manager are recognized. TPM 1.2 is active and working with e.g. the client security solution and fingerprint software. I thought the UEFI / BitLocker issues have already been solved?!Is there still an issue with the UEFI only mode of the W520?Any thoughts or a bios update within sight? Thx in advance,nasenbaer

Answer:Windows 8 Pro Final (9200) BitLocker in UEFI mode not working, Element not found

Haven't heard of this issue with Win8.  The issue with Win7/UEFI/bitlocker from last year is definitely solved.
 
Does this link help?

EDIT:  I tried this just now with Win8 Pro on T420 (same BIOS code base as W520) in UEFI mode.  And bitlocker works fine.  So I'm sure what problem is happening on your W520.

So, I've been trying to get all of the machines in our organization up-to-speed on the latest standards.  I figured that, as long as anyone is getting any NEW machine imaged and set up for them, that machine might as well be set up in UEFI mode, with GPT partitioning, as those are the latest standards for PCs.
We have a lot of Dell machines, and I have had no problem getting tons of them booting to my Windows 7 Professional installation USB drives, in UEFI mode, and installing a build of Windows in UEFI mode, using GPT partitioning for the drive.  E6320s, E6430s, E6440s, all work fine.
The Latitude E7250 doesn't even detect the USB drive that I plug into it, that has worked flawlessly for so many other machines.  I have the latest BIOS (A13).  Secure Boot is disabled.  I have tried plugging in the USB drive in a USB 2.0 port on the E-Port Plus docking station.  I have disabled USB 3.0. 
The machine does not detect USB devices in UEFI mode.
This is a laptop that costs north of $1,000, Dell.  For real?

Answer:Latitude E7250 - doesn't detect my Windows 7 Professional USB reinstallation drive in UEFI mode

This is not Dell's doing - it's Microsoft and Intel at work.  They removed the ability to boot Skylake-based systems from USB to install WIndows 7:
wccftech.com/.../
While you can find ways around it (see below), whatever reasons you have for running Windows 7 should be very seriously rethought now -- the Skylake platform is the very last Intel platform that will run 7 -- the soon to be released 7th generation (Kaby Lake) CPUs will not run Windows 7 at all.

Answer:Changing UEFI mode to Legacy mode

Hi, If your HDD has a guid partition table, the current OS will have to be installed in 'uefi' mode - the only way around this would be to reformat the drive with MBR and reinstall the OS using a boot option ( cdrom or flash drive ) that does not have a (uefi) suffix. Regards, DP-K

Question 1:I am unable to load the Windows 8 Installation DVD in UEFI (only) mode on my T420s. As a result, I can only run the installer in Legacy mode (or both UEFI/Legacy which effectively means the same thing). This in turn means Windows 8 is installed in Legacy BIOS mode.  Any idea how to install it in UEFI mode? I am using a DVD burned using the Windows utility from the Windows 8 64-bit ISO and have followed the instructions in HT073269, however I am unable to get to step 1 of the Windows 8 install after updating the BIOS, resetting to defaults, and switching to UEFI-only. On boot, after switching to UEFI-only, I am presented with a bootloader and prompted to select which drive to boot (DVDRAM or SSD). Selecting either makes the screen go blank for a moment and then returns back to the same screen with no result. Since then I have searched these forums extensively and Googled Technet, Notebook Review, and other sites to no avail. I've tried several several ideas, including using diskpart > clean to get the SSD in raw status (per HT051844). That did not make a difference. I also tried converting a Legacy-BIOS install of Windows 8 to UEFI using CharlyAR's instructions on TechNet (linked from another thread here). That seemed to get me to a Windows Boot Loader but still errored out and Windows Repair was unable to fix it. Any suggestions? Also, question 2:  Does anyone know if the T420S support secure boot?

Hello. So i got automatic repair after changing boot order from UEFI USB KINGSTON to P1 Samsung SSD 840 EVO. I am able to get through to Windows 10 but after restart after automatic repair. So i am needing 2 boots now.

Screen:
And my question is this related to my switch between UEFI and NON UEFI device or that doesnt matter?

My motherboard is Asus Sabertooth Z97 Mark 2.

System was working fine few days on P1:Samsung SSD ( MBR ). Problem appear when someday i just change again ( maybe my 5 switch ? ) boot order from UEFI USB KINGSTON to P1:Samsung SSD ( MBR ). So is this related to this or that doesnt matter?

Answer:Windows 10 Automatic Repair - switching between UEFI and non UEFI devi

First of all, you dont need to change the boot priority in order to boot from the USB. Use the "Boot Menu" key for this purpose.

In a UEFI system, the disk should boot as a UEFI disk.
If you load the defaults in the BIOS, does it boot back to the SSD? Let us know.

Hi,
I Just bought 25 Thinkpad T431s Laptops for my company (@ISRAEL)All of them came with windows 7SP1 Installed And Recovery is Windows 8 (not 8.1 even though 8.1 is out for a yr!)
The Install process takes 3 Hours!!! Just for upgrading to windows 8.Then I need to upgrade to 8.1 - the process is about 3 hours more! Because I need to Register And create Microsoft account for each user then to verify the account.After that I need to Log with the account to the PC And then Download the update (3.5GB) And Install it.
IS ANYONE AT LENOVO THINKS THAT ITS ACCEPTABLE?DO I WORK FOR LENOVO? DO I NEED TO SPEND 6 HOURS FOR UPGRADING EACH LAPTOP?
Don't forget that after that I need to uninstall all the bloater from the PC. Like Symantec AV (Because Enterprise company's uses Enterprise Class AV, FW And other software. We uses Kaspersky Enterprise, ESET, And others...)
AND ABOVE ALL.If I want to Install Original Windows 8.1 I can't!Because the OS Recovery DVD is not bootable And contain special recovery files with special extensions. Also, there is no PRODUCT CODE! Just "WINDOWS 8" sticker logo on the back of the notebook.

Answer:NO Lenovo Windows 8.1 Recovery DVD for CLEAN INSTALL! + unable to Install UEFI MODE

Hi ohad, welcome to the forums,
 
I'm sorry to read about your experience. 
 
I don't work for Lenovo but it would appear to me that something may have gone wrong at the sales / purchasing stage; to my knowledge the T431s is only available with Windows 7 preload, (with Win 8 recovery discs in some cases as you have), or with Windows 8 preload. A Win 8.1 preload doesn't appear to be available for the system, but I stand to be corrected on this.  If you required Windows 8.1, in my opinion the better option of the two, would have been a system with the Win 8 preinstall as this would only require updating to Win 8.1
 
Unfortunately I also can't envisage Lenovo creating a factory image for the T431s because it must be pretty near end of life.
