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.
My next attempt would be to try and install 8.1 Pro fro... Read more

Yes that is correct, when you load a different OS on the hard drive. All previous partitions are wiped off of the hard drive. Only way to get it back, is to reinstall Windows 8.x.x.

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. This is the preferred way to set it up. == This will help you with the install Clean Install Windows 7

Hello !
The EFI partition contents is related with a specific windows installations or with PC's UEFI ?
For example :
Let's have 2 PC :
- Different hardware
- GPT (Different / or Same ) Partition scheme
- Same version and editions of Windows 8.1

What can we say about EFI partition contents on these 2 PC ?
Thank you !

Answer:Efi partition is related to windows installation or UEFI

The EFI partition is the System Boot Files Partition (ie System partition)

GPT is a different partition format (allows more then 4 primary partitions, MBR only 4 primary partitions)

I want to install Windows 7 Pro 64 bit on Sat Pro C50 (downgrade if you like - supplied with Win 8), but I want it UEFI booting, with GPT partitioning.
I am happy to wipe existing partitions if that solves problem.

I _have_ disabled Secure Boot.
Booting Win 8 install DVD works;
Setting CSM boot and booting from Win 7 DVD works - but this isn't what I want.
Setting back to UEFI boot and boot Win7 install media - locks up at "Starting Windows" screen.
Media _is_ good, works OK on other manufacturers' PCs.

I am not convinced this is a Microsoft problem.

Answer:Satellite Pro C50: Installation of Win 7 using UEFI boot mode

Hi

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?m trying to install window 7 on TOSHIBA Satellite M50D-A-10L with UEFI boot.

First time, I used EFI installation with CSM Boot and it worked fine.

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.

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.

Hey all, this is my first post but have been an active reader for sometime, ive searched for this problem on the forum but have not found anyone in my prediciment?!?!

2 week old C50 was pulled off table by the hound so I lost the screen but HDD was ok as its been slaved up to my mac while the screen was fixed so I could keep working.

Answer:Win7 installation on Satellite C50-A-1JN - missing UEFI options

>how I can update the bios without windows and with the old bios not allow me access to the USB or CD?
This is not possible.

You need installed Windows system in order to update the BIOS.
If you did not create the Recovery disks (or USB medium) in the past, you could order the recovery disk (containing Win 8.1) on this page:
http://backupmedia.toshiba.eu/landing.aspx

Then you could recover the notebook back factory settings (Win 8.1) and could update the BIOS.

_By the way:_ did you try to change the Boot Mode without BIOS update?
Disable secur boot within Bios, save changes. Then boot in to the Bios again and now you could check if the CSM mode would appear as available option.

Hi,

First of all, let me say that I understand written English, but very poorly written and would like to apologize ...

Is it possible not to have the partition "recovery"?

Because if you look at the two tutorials:

- UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums

- UEFI (Unified Extensible Firmware Interface) - Install Windows 8 with

In the tutorial to install Windows 7 in UEFI, there is not that damn partition recovery, while in the tutorial for Windows 8, we can see it.

When I install Windows 7 (MBR mode), I avoid this partition "recovery" by creating a partition with a name before installation. I install the OS on it and everything is fine, no partition "recovery" But here, since one must delete all partitions, is there a solution? If I create a GPT disk with a partitioning tool before installing, is that it might be appropriate?

Tomorrow I get a DVD (OEM) of Windows 8, and so far I've never installed UEFI, I would avoid the nonsense.

Thank you for your answers.

Answer:Satellite L655-1DV - lost partition after new Win 7 installation

Hi

How did you install the Windows 7 on the HDD?
Did you format the HDD during the setup procedure?

The Disk Management shows only one partition. That?s really strange because even if the HDD would be formatted, you should get at least two partitions (one small partition for Win 7 restore files and one bigger system partition C)

I think you should try to change the C partitions size within the Disk Management.
Click right on the partition and decrease the partition size. Then you could create new partition and could mark it active.

It would be very interesting to know how the partition would appear in Windows explorer.

Yes. This is how I do any OS tests\'dual boot'\experiments etc with zero chance of damage to the original boot OS\hd. Am keeping a bunch of old HD's for the purpose. The downside is the slight risk for some mechanic\connection problems, just be careful, remember to power down! So if you don't find it troublesome to switch HD's, IMO go ahead and try that route.

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.

AHOY!

I've got a Satellite Pro A300 PSAGDA 2000R

It had Windows Vista installed when I got it but after a while it needed a reformatting so I did, (I like to reformat my computers every 6-12 months on average), it only came with XP discs even though it's got a serial for Vista on the underside of the laptop so I installed XP. That was about 2-3 reformats ago now.

However while looking for drivers I saw mention of a hidden partition for reinstalling Vista (which hopefully is 64 bit) and attempted to do so numerous times but unfortunately it didn't work, I'm assuming that perhaps when installing XP I may of accidentally deleted it or something? (Would of thought they'd of made it on some solid state memory that couldn't be written over or something.)

*Is there any way I can access it, get another that won't cost a ridiculous amount of money (eg download) or someone kind enough to create a image to upload to a file sharing site or something that I can download?*

Hi,

my Satellite L40 PSL48E came with a Vista recovery partition.
As I despise Vista I bought a replacement drive and installed a new hard-drive and installed XP pro.
I retained the original drive in case i ever had to claim under warranty.

I now find that due to work commitments I have to occsionally use the despised Vista rubbish and wonder if it is possible to create a Installation disk from the partition on the original drive so tha ti can create a dual boot system on my new drive.

I am very reluctant to BUY a new Vista CD since I already have a fully legal copy on a drive which I am not using and I will only use it VERY rarely for this one work commitment.

Any information gratefully received

Thanks Ron

Answer:Re: Satellite L40 PSL48E: Can I create a installation disk from Vista partition

Hmm?. If you have a HDD recovery option then a full image was placed on the HDD and usually all notebook with HDD recovery option supports an Toshiba tool called TOSHIBA Recovery Disc Creator.

Using this tool you could create a Vista recovery DVD If the Vista OS was damage you could also try to boot the notebook pressing the F8 button.
This would enable a advanced boot menu.
Here you should choose ?repair the computer?

But note; this possibility is only available on notebooks with ?HDD Recovery?

I wish reinstall Win 7 on my new unused Samsung 840 Pro 256gb SSD. I have a new OEM SP1 Home Premium 64 bit installation disc that has never been used.
I thought this would be a good opportunity to set it up in the UEFI mode, however I am not sure how to make sure it will use the UEFI loading.
My specs are up to date so you can see I have a very recent motherboard & CPU. I believe I will need to set the BIOS settings to UEFI in all cases where necessary & to set AHCI as well before installation. Is there anything else that I should be aware of.
I will rely on the installation to set up the partitions as needed as I don't want any special partitions.
Is there anything I need to do to the SSD before hand. Samsung provide a DVD that has cloning software on it which I would not be using, but I would use the SSD maintenance program that is also on the DVD. I assume I would run that after OS installation.
Any suggestions or warnings are most welcome, to make this as easy as possible.

Answer:Win 7 UEFI installation on new SSD .

Hi there.

Yes there are a few extra procedures to running on UEFI.

What is the specific reason on why you want to boot off UEFI and not a legacy bios boot? I will be honest there isn't a real difference in booting performance. The normal reason why is a MBR (legacy) doesn't support disks over 2TB and GPT (UEFI) does. If you don't understand the difference I suggest you just install Windows normally as there isn't a major difference.

You can use the SSD as is, you don't have to use the UEFI "GPT" drive format.

However, is the Win 7 64 bit Professional you have an "OEM" version or a full license version? If its an OEM version legally it is only licensed for the original PC (motherboard) it was installed on. Its iffy on whether Microsoft will activate an OEM on a different system. If its a full version there shouldn't be any problem activating it on the new motherboard.

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.

Answer:Installation on 3TB disk (Non Uefi)

If you want to have your boot drive GPT, then it has to be UEFI boot.

For non-EUFI, I believe your only option is to partition the drive into a 2TB and a 1TB partition and install OS on the 2TB partition.

You can do MBR which has 2TB limitation or GPT which requires EUFI for boot drive, but those are your options.

(You can have GPT for non boot drives without EUFI though so you could also use a different drive for boot)

USB 3.0 is not recognized in your BIOS/UEFI shouldn't matter main thing to understand is that it needs to be formatted Fat 32 See the tutorials for UEFI Install you won't have any issues

I'm trying to install win7 on a new intel ssd. I setup a USB drive as a uefi boot and I can successfully boot the install program from it. However I stored my ssd driver files on that same USB drive.

When it is time to install on a drive it doesn't see the ssd drive (which is expected). I then try to load the driver for it. However when searching for the intel ssd driver all I can see is the ramdrive the installation files created. I can only see the boot drive x:\ which has only windows installation files. How can I navigate the USB drive at its real root during this part of the installation so i can point it to my driver files?

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.

ADVANCED:

XHCI - It's set to Auto, other options include Enabled, Disabled and Smart Auto. I have no idea what this function is and i assume i should leave it.

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:

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

Skip EFI Image in CdROM - I should disable that I guess/
__
SOOooo.. Is there anything I should know about, especially about the settings in the Advanced section? If someone could explain what they are I would appreciate it very much. I'm greatful for any tips you guys could provide.
Thanks in advance!

I am trying to create an autounattend file to install Windows 10 as a UEFI install. I am encountering one problem when it comes to creating the partitions in the unattend file. Windows 10 creates 4 partitions, 3 of which (MSR, EFI and OS partitions) I have no trouble with as they are roughly the same as Windows 8.1 just different sizes but the new 4th partition, a 450MB "Recovery" partition, I can't seem to create.

When installing Windows 10 it lists the partition type as "Recovery" but using WADK there is no option to set "Recovery" as the partition type, the only options are EFI, MSR, Extend, Logical or Primary.

Can anyone tell me the exact attributes/settings required to create the new 450MB "Recovery" partition in an unattend answer file?

My searches on the web so far have not turned up any helpful information regarding this new partition created by Windows 10 so hopefully someone here can help me.

I've downloaded Windows 7 and made a bootable USB drive. I installed Windows on a couple of PC's and my HP laptop. I've noted that when installing on laptop, I've had some issues. In BIOS settings, the boot mode was selected to UEFI and no matter the boot sequence, it just wouldn't boot from USB (note: there was a USB Hard Drive and a USB Generic Volume option and I've checked the 'boot from USB device option' above). I've solved the problem by switching to Legacy boot. It booted from USB with no problems and Windows got installed correctly. I've done the same thing on an another HP laptop, (same thing, UEFI wouldn't boot from USB, while Legacy would) only this time to see that all of the partitions are formatted as GPT and I get a message saying that Windows can't be installed on a GPT partition. I am presuming that this is due to the legacy boot mode (my overall knowledge is very low, so if any of this doesn't make sense please forgive me).
I was wondering if there is ANY way I can install Windows 7, or higher, I don't care, on this laptop? Thanks for your time

Hello,
 
I have a HP envy x2 which has no uefi partition and at the moment it seems that it's impossible to reinstall this computer. I have tried external dvd-rom and bootable usb, but they aren't recognized when I turn on the computer. At the moment the computers has no OS.
 
On hp forums I read that you must turn on legacy boot in order to be able to boot from cd-rom, but there is no such option, there isn't even a boot priority option, only uefi boot priority which is greyed out at the moment, probably due to absence of uefi partition.
 
I have never seen such basic bios with so few options, I couldn't believe that there is no boot priority options available, which seems the most basic of options...
 
Is there anything that could be done in this situation?

Hi,

My system partition is set to MBR, so access to UEFI from advanced startup options is missing.
I accidentally set the boot order to external HDD first, so whenever something is connected and I restart the computer, it tries to boot from the external device.

I can't convert the disk to gpt without formatting it, and the system is there so that's problematic.

Is there any way to do it anyway?
I thought EasyBCD BIOS Extender could do the job (it can't).
Maybe boot from an external device?

Thanks.

Hello all.

I am running Windows 8.1 on my Acer Aspire V5-571PG. Well, Windows 8.1 may be a stretch.

Months ago, I decided to switch to a dual-boot configuration of Windows 8.1 and ubuntu. To accomplish this, I switched my bootloader from UEFI to GRUB. I decided ubuntu was not for me, and rather than looking up uninstallation techniques, I simply removed the ubuntu partition and used a third-party tool to reallocate the empty space to my Windows partition (I somehow managed to create my ubuntu volume to the left of the Windows volume so that was a complete pain). Now I am stuck with a GRUB startup scheme, displayed in pictures below:
Above is the first screen. I figured out that to navigate to the next menu, I have to type "exit." After I first type "exit" and hit enter, the same screen comes up. I repeat the process and the next screen is shown:
When I select "Windows Boot Manager," I am able to successfully boot Windows 8.1.

I also checked my disk partition settings and I infer that I have also mistakenly deleted my recovery volume:

Any help and direction in repairing my disaster of a bootloader would be much appreciated!!!

Answer:deleted ubuntu partition, restoring uefi

Go into the BIOS and under Boot Options delete the Ubuntu as a boot source. Then move the Windows Boot Loader up in the boot order to boot first. This has worked for me.

Hi there, Aladil           -
 
Thank you for writing in to the Lenovo Forum - happy to have you here today.
 
You can't install to a GPT drive because you are booting in legacy mode. You'll have to boot in UEFI mode.
 
If you want to install in legacy mode you'll need to convert the drive to MBR - or at least clean it so the installer can partition it MBR-style.  Boot the install media, hit SHIFT+F10 to get a command prompt window, and run DISKPART:  list disk, select disk, clean, exit, exit.  Then let the installation continue.
 
Update us how it goes.

(A large portion of my issue and what led up to it resides here)

I know barely anything about boot managers and whatnot. This is a part of a long series regarding other problems I've had that I posted previously here a while ago, but no one seemed to know anything about it (although the above link is to another forum).

Well I had gotten past that original problem by forcing the "UEFI DVD drive" to be booted instead of the "BIOS DVD drive" version, as I have the option to pick either type (as to utilize a GPT format instead of an MBR format, I do have a UEFI motherboard by the way). As I try to install Win7 x64, it creates the GPT disk and MSR and EFI partitions correctly, but when the setup restarts for the first time, inbetween the "Installing Updates" phase and "Completing Installation" phase, it gives me this error:






Quote:
Windows could not finish configuring the system. To attempt to resume configuration, restart the computer.


I tried to manually create the GPT disk and EFI, MSR and primary partitions but no change. I tried different permutations of boot orders and nothing changed. Now, I can successfully install Win7 via the "BIOS DVD drive" and use a MBR style disk instead, and it installs fine. The only caveat is I can only boot up Windows in MBR format if I have the installation disc in the DVD drive, which is silly, and refuse to settle for.

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.

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?

You are resetting the UEFI/BIOS firmware to UEFI boot & booting the DVD/USB in UEFI mode, than installing in UEFI mode, than after install you are resetting the UEFI/BIOS firmware to Legacy boot.

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.

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!

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.

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.

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"

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.

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.

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??

Hi, I am trying to perform a clean UEFI installation of Windows 7 with SATA mode switched to RAID. I have two identical HDDs for RAID and 80 GB Intel 310 to put the OS on. The BIOS/UEFI can see all 3 drives and the two HDDs are configured for RAID through the CTRL-I utility When I start the Windows 7 installation, it does not find any hard drives and prompts me to load mass storage driver. I tried loading Intel Rapid Storage Technology drivers through USB flash drive, and the installation correctly displays "Intel(R) Mobile Express Chipset SATA RAID Controller", but after couple of seconds of loading when I click on Next, it comes back with the same result, no drives found. I tried switching SATA mode to AHCI and the installation recognizes all 3 hard drives just fine. Any help would be greatly appreciated.

Good day,

I have an Asus Z68 mainboard with UEFI-BIOS. Windows 7 Professional 64bit is installed in UEFI mode on a GPT partitioned drive (SSD). It worked flawlessly.

Now I added my second, old harddrive, that is still MBR formatted.
Windows won't start anymore, instead I am seeing "Windows is loading files", then a blinking cursor, and that's all.

I have two options in BIOS regarding boot priority:
1) I can boot from the SSD as primary priority
2) I can select an option called "Windows Boot loader", I think this refers to the UEFI boot code that Windows wrote to the UEFI.

If I select the first option, I get the "Windows is loading files screen" and then the "Windows has detected a startup error, do you want to repair the system startup" screen. If I select "Start Windows normally", I get a blinking cursor and then nothing. If I select "Repair startup", I see "Windows is loading files", and then again the "Startup repair screen". It is an endless loop.

If I select the second option, I get "Windows is loading files", then a blinking cursor, and nothing more.

Is there any way to get my Windows to boot again without disconnecting or re-partitioning the old harddrive?

Note that the old harddrive is NOT for booting, as it is just a datastore.

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.

Nothing with the Command Prompt is helping me either, i have done 'bootrec /fixmbr', 'bootrec /fixboot' and 'bootrec /rebuildbcd', but the last command returns the following error:

If you didn't guess, the OS here is Windows 8. The internet is full of threads on this topic, but every single one is answered in one or more of the following ways: The first type of answer is something the OP has obviously tried already like "Press F11 to get to the recovery partition". The people writing this don't realise that a clean install of Windows on C: also erases the old UEFI and replaces it with a useless one that isn't linked to the recovery partition.

The next type of answer is "why?". There are at least two painfully obvious reasons why someone would want to restore their laptop to factory condition, but asking which one is entirely off-topic. Until admins ban the question we're all going to have to learn to ignore it.

The rarer type of answer is the one that you can have some respect for. Probably something about active partitions, boot flags or even diskpart if the person knew how to fix this in Windows 7. Bravo to those people.

Some people don't even read the OP, but reply anyway, which is why I've put some things in bold and left the words "recovery partition" to the end of the title. Hopefully they won't see it.
But with Windows 8 and EFI none of that old stuff works anymore. In fact nothing that I'm familiar with seems to work at all anymore, it's all new. It's like being 20 again and not really knowing what's gonna happen when you hit enter.

The hard drives are 120 & 128 GB SSD SATA. On one drive I have Ubuntu installed. I want to install Win7 on the other.

Initially when I first installed Win7, it created 3 partitions, ESP, MSR, and the OS. However do to some glitches with dual booting, I had to delete both OSes and start again.

When installing Win7 now it is no longer creating the 3 partitions, just 2, MSR & OS. I am trying to get it to create the ESP partition. The hard drive is GPT.

Answer:Win7 installation on UEFI system issues

You have to boot the DVD in the UEFI mode. If you have an F key to give you a boot device menu, use that. If not, go into the bios and select the UEFI DVD entry.

Did you install Ubuntu as UEFI?

But a GPT drive has a hidden partition, which you say it created earlier. If the drive is already GPT, it does not need to be recreated. It might only create a EFI and OS.
I tried several different ways to show only 2 partitions, but even when I preset the drive to GPT, it still showed a 100 MB, 128 MB, and OS.

UEFI can install like MBR in that it may use a single EFI partition for both UEFI installs. So installing with one drive disconnected might be beneficial, but your choice

I have read the tutorials and the many posts on this topic so apologise for creating another post on an old topic. I am hoping I am being an idiot and have just missed something really simple.

Scenario 1: Created UEFI bootable USB, using Rufus, configured BIOS with CMS disabled and Secure Boot enabled. USB drive is recognised in BIOS as UEFI and selectable as a boot option. Windows files show as loading and then it sits with the Windows logo doing nothing.

Scenario 2: Created 'normal' bootable USB, using the Windows Download Tool, configured BIOS with CMS enabled and Secure Boot disabled. USB drive is recognised in BIOS but not as a boot option. Get a message prompting to insert boot media.

I don't have a DVD drive so USB is my only boot option. The system is a 3XS Scan custom build but the OS stopped recognising mouse and keyboard even in safe mode so I opted to wipe the hard drive and start with a fresh build. The OS was being unstable anyway and it was time for a clean install.

This is the first time I've tried a build since UEFI has started rolling out and it's nowhere near as straight forward as it used to be... Just used to pop a USB or (remember these...) a floppy to a basic command line to set up the partitions and load up the OS. So, what I am really saying is that I am utterly clueless in this new world order and will need handholding...

Thank you for any help and suggestions.

Can i format (in GPT mode) and partion my hard drive prior to the Windows 10 setup?

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.

What is the benefit of installing in UEFI vs Legacy? All I understand is that the system sets up more partitions.

It might be worth it to make a sticky referencing the Windows 7 tutorial for creating USB flash installation media, specifically the part 11 about moving the EFI files around. I have been bashing my head trying to figure out why my laptop refuses to acknowledge ANY USB Media (never tried CDs) and the conclusion I came to was that my laptop had booting from USB disabled, NOT that the ISO still doesn't have working boot files when flashed with Rufus.

It would've been nice to know before caving and upgrading (and subsequently downgrading) my Windows 8.1 install.

I am sorry that I'm ranting about this, but I honestly did try searching the problems and such, and not finding anything I assumed that it was a problem with my specific hardware.

I'm sure it is obvious where to find it, but it would be nice if in the installation and setup forum there is a sticky with links to relevant tutorials (such as setting up dual-boot, making a USB flash drive, installing the TP in a virtual machine)

Answer:Booting USB installation media on a UEFI system.

I am going to try tomorrow morning and see whether I could install Win10TP with the bootable USB drive, I always use the DVD but would like to try the USB disk.

Hi there, I just tried to install Win7 in UEFI mode from a usb thumb drive onto my X220.Unfortunatly my SSD (Intel X25-M 160GB that came with my X220) isn't recognized by the Windows setup. Tried to load RAID drivers from Intel but this doesn't help. Any clue how to get around this? Thanks,Chris :-)

Okay, my graphics card, Nvidia GT650 is not ready for UEFI installation and I have no way to flash the bios. If I boot using legacy bios, install the card, then can I flash the card BIOS and then return to UEFI booting?

The card is currently not installed and I have no other system to use to flash the cards bios. TIA!

Answer:UEFI to Legacy for graphics card installation

Did some research and it appears after you disable UEFI, in order to install the card, you can then reboot and enable UEFI and it will reconfigure the UEFI with the new card.

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 installed Windows 8.1 on UEFI mode on my new Samsung 840 Pro.

Everything works REALLY fast which is great, the UEFI boot process is significantly faster than the old BIOS

Problem is, after enabling secure boot in the BIOS, I am getting an error message saying
"System BIOS detected a non-Windows 8 Logo graphic card. There is no GOP (Graphics Output Protocol) support detected in this card. 'Windows 8 feature' settings in BIOS will be changed to 'Disabled'."

I am not very savvy about Secure Boot, but from what I understand I need to get a special UEFI bios for the graphics card in order to get this to work?

My board is an MSI Z77A-GD65 and the GPU is an EVGA GTX680 Superclocked.

P.S. When loading Windows with UEFI enabled I should see the manufacturer's (MSI) logo instead of the Windows logo right? I'm not seeing it but I have definitely installed 8.1 in UEFI mode and my BIOS mode is set to UEFI only so it's definitely working, I assume that it's related to the "Non Windows 8 logo graphics card" error?

Thanks

Answer:Secure Boot issue after 8.1 UEFI installation

Curious what happens if you disable Secure Boot? As long as you keep your system clean, check for virus/malware it shouldn't be a problem.

Otherwise, read here: GTX 680 / GTX 590 - UEFI BIOS | EVGA Forums

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

Hi there I?m after a little help.

Yesterday I installed a program called partition magic. The install went without any errors or problems but then when I start the program for the 1st time I got a blue screen and my laptop shut down. I restarted the laptop and uninstalled partition magic but now I noticed that the data partition is missing. I?ve tried doing a restore back to before I installed partition magic but that does not help.

Any help would be great. Thanks

Lee

Answer:Re: Missing data partition after installation of partition magic

Hi Lee,

May I ask you why you have installed partition magic? Installation of such programs is always a little bit risky and should only be done if you really want to change some partitions or something else.

Have you already checked disk management of Windows? Navigate to control panel > System and Security > Administrative Tools > Computer Management.

Can you see the second partition and is it maybe hidden or something else?

I was reading about Bitlocker and noticed this:






Because pre-startup authentication and system integrity verification must take place on a partition other than the encrypted operating system drive, BitLocker requires that your computer has at least two partitions:

An operating system partition (usually drive C) that is formatted with NTFS.A system partition that is at least 350MB. This is where Windows stores files needed to load Windows at boot. The system partition must not be encrypted and should also be formatted with NTFS for computers that use BIOS firmware and with FAT32 for computers that use UEFI-based firmware. This drive is often hidden in Windows Explorer. You can configure one or more partitions for your data (drive D, E, etc.) and enable BitLocker on them.



Securing Windows 10 with BitLocker Drive Encryption Microsoft MVP Award Program Blog

On my UEFI PC's (on which Windows 10 was installed in UEFI mode), Windows created a 450MB NTFS recovery partition and a 99MB FAT32 no name partition. Which one of these are they talking about above, and does this mean that I cannot enable bitlocker because there is not a 350MB+ FAT32 partition?

Answer:Windows 10 System Partition Requirement UEFI - NTFS or FAT32

A system partition that is at least 350MB



You have a 450MB Recovery Partition, and a FAT32 File system partition, so you are good to go.

Hi,I'm attempting to create a VirtualBox machine of my physical laptop which is running Windows 8.1. I've created a separate partition where I installed Windows 10 so I can dual boot.I've been following these instructions:http://joaodrp.com/blog/2016/03/19/migrating-a-uefi-gpt-windows-8-10-machine-to-a-virtualbox-vm/In VirtualBox, I have sucessfully gotten the VHD file attached to the virtual system and I used an DVD ISO Installation of 8.1 and booted into the advanced recovery area where I can use the command prompt to make changes to the vhd. The command prompt should allow me to rebuild the mbr record which is outlined in the instructions. One of the issues is that this Laptop's physical drive's recovery partition was deleted.

Hello,

I'm currently reinstalling entirely windows 10 x64 with uefi , hardware fast boot, and secureboot.

I'm a bit confused because win 10 installer set:

Recovery on partition 1
System on partition 2 (win re)
MSR (not formated) 3
Then System (c at end of the other partitions.

First, contrary to every microsoft guides for win 10,
WIn 10 installer set Recovery at the left side of the drive.

Usually in win 10, it should be set at end ( right) just after C: so windows 10 can shrink the partition to let for future usage, win RE expand.

I would like to know if it's a good feature or a bug.

Next is it normal on a samsung F3 512gb 512k sector, efi fat 32 partition been selected as a 99MB ?

Usually it's 260mB for 4k sectors, and 128Mb on my old win 7 install.

I would like to know if i have to manually format the hard drive and set partition so Win re is at end, and Efi been larger ?

Thanks a lot.
