Should I enable UEFI Boot in BIOS before Win 10 install?

Question: Should I enable UEFI Boot in BIOS before Win 10 install?

I built a computer back in 2009 with an Intel DP55KG motherboard running Windows 7. So, I am getting for a fresh Windows 10 install and I noticed that back in 2009 I never enabled the UEFI boot mode. Would it be recommended to enable it this time before the Win 10 install, or will it bring about some issues?

Here is the definition of the setting according to the motherboard manual:

UEFI boot
OPTIONS: ? Enable ? Disable
Enables or disables Unified Extended Firmware Interface (UEFI) Boot. UEFI Boot must be enabled in order to boot to a drive larger than 2 TB (terabytes). Enable: BIOS will attempt to boot via UEFI before using the legacy boot sequence. Disable: BIOS will use the legacy boot sequence.

Preferred Solution: Should I enable UEFI Boot in BIOS before Win 10 install?

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.)

UEFI mode is pretty much the standard used by PC's today..
supports larger disk drives and up to 128 partitions per drive..

We are pushing a new image this summer but we need to make boot and file system changes, my boss wants me to automate this process. the goals are to desable legacy in bios, enable UEFI, select PXE,  change UeFI boot order (usb,cd, NIC, Hd) using the Bios configuration tool at command line. I have the config.ini file from the bios. can I make all those changes at once or do I have to reboot in between enable UEFI and changeing the boot order The why: we are moving from MBR to GPT with the new image Win10, and we save time on the boot by disabling legacy. The boss says so. (the short answer) any tips or suggestions welcome.

Hello, I have a T420 4180-LVP, and recently I updated the bios to 1.43 (I think it was this update that caused my discomfort) and am no longer able to perform the boot for install (with dvd or usb, none of the right) windows 8 when I enable UEFI Only in bios. How do I install windows 8 secure boot on my thinkpad?

Answer:T420 4180-LVP bios 1.43 not boot to install windows 8 with bios options UEFI Only

Hi, carlosrrjr
 
In the BIOS, there should be a settiing for Secure Boot, and it is likely set to Enabled. If this is set to Disabled, and the Boot Order settings are set properly, then you should be able to boot from external devices like a DVD. Just make sure the Optical Drive appears before the Hard Drive in the boot menu. 
 
Hope it helps,
Adam

rdubayah,
If your computer was running WIndows 10 without any issues prior to downloading the Anniversary update, then you would not have had to change any settings in the bios to install the update.The UEFI and Secure Boot settings are to enable booting with a USB or DVD to install Windows.
Disable Legacy Boot Mode and Enable UEFI
Start the computer and TAP the F2 key to enter the bios. Once in the bios Press F9 to Restore the bios to the Default Settings. F10 to save changes and exit. You could have a hardware problem. To run a hardare diagnostics on the computer you would start the computer and TAP the F5 key. Insert a cd/dvd in the optical drive for running the diags.

I have a new Precision 7710 with a 2.5 inch 1GB SATA SSD (system boot=Disk0) and a 1GB NVMe PM951 SSD.
I have been attempting to install Windows Server 2012R2 on the second, M.2 SSD (Disk1) into a GPT, NTFS partition.
Since this system has no DVD, I made a bootable UEFI thumb drive with the contents of the .iso installation for Server 2012R2.
The thumb drive boots OK and I can begin installation, but when it comes to choosing the target for installation, the M.2 SSD is not visible in setup.
The M.2 drive is clearly visible inside Windows 10 Pro as the D: drive.
So...I mounted the .iso setup file in Windows 10 and ran setup.exe. The install began and could see the target M.2 drive, and began loading files on the second SSD. It then attempted the first of several restarts that come with this process with the new Server 2012 R2 environment.
It sucessfully modified the Windows Boot Manager before the restart, then restarted, and the setup program gave an error because it could not find the target partition on the second SSD.
The setup environment then modified the Boot Manager to "Windows Setup Rollback" and proceeded to enter an infinite loop, attempting to delete files from the unreachable M.2 drive. I manually choose Windows 10 on the boot menu, and once booted changed Windows 10 back to the default OS.
I've tried several things (turning off Secure boot, changing from UEFI to legacy bios--it won't boot at all that way) , but I can't get that second disk t... Read more

Hello,
I am having problems with direct booting into Windows 8 installed into a VHDX file.
This is a four-partition UEFI boot on a GPT drive. EFI files are residing on a second partition of disk 0 (the ESP partition) in the EFI folder. The boot virtual disk is residing on the fourth partition of that disk 0.
When I turn on the PC, it shows black screen after the BIOS POST screen. No Windows 8 boot menu, no other information is displayed. However, if I press Shift+F12 (or F12) to start Dell BIOS Boot Menu and choose Windows Boot Manager from the UEFI part of
the boot menu, Windows 8 starts to boot without difficulties.
How do I make Windows to boot automatically without having to select Windows Boot Manager in DELL BIOS boot menu?
I believe I messed up with boot sector somehow... What needs to be fixed provided that Windows 8 will boot into VHDX file?
Thank you.

Well this is the world we live in And these are the hands we're given...

Not sure if this is a Boot or Operating System issue so let me know if I need to move this to the other board. I'm trying to enable virtualization on my computer, which can only be done from BIOS (or apparently in the case of Windows 10 UEFi). I've followed various tutorials online to access UEFI (Shift + Restart > Troubleshoot), but when I get to the troubleshoot menu where there should be access to UEFI-Firmware, there's just a link to Startup Options/Settings (I can't remember the name of it exactly as obviously I don't have it in front of me right now). From what I've read the access to UEFI can vary depending on manufacturer, so I was wondering if HP might have moved access to UEFI somewhere else? Any help ASAP would be much appreciated as I need access to this to study!

Answer:Access BIOS/UEFI (Enable Virtualization)

Hi, You should be able to access this as follows. Shutdown the notebook. Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu.  The option to enable virtualization should be found under the Advanced tab.....Device Settings.....Device Configuration. Regards, DP-K

**** You need to enable Legacy MBR by Enabling Launch CSM in the EFI Setup ****

Hello all,

This is my first post. I am a Windows 7 user and now (against my will) Windows 8.

I bought an ASUS N76 laptop pre-loaded with Windows 8 so these are the new generation n76 series. The old ones come with Windows 7. Anyway...

I attempted to boot a Windows 7 ULT 64 install DVD but the install hangs on the Windows logo/flag. So...

- Windows is loading files is shown and hidden
- The animated Windows logo appears and then it just hangs....go figure

I have no idea what is going wrong. I went into the UEFI setup and the only option for my BR is EUFI boot.

I also added a "boot option" asking the EFI to boot "efi\microsoft\boot\boot.efi" or "\efi\microsoft\boot\boot.efi" but when selected (from Boot Override), the screen goes blank for a few seconds, the BR starts spinning and I am thrown back at the EFI so it looks like it cannot find the file. For path, I selected the BR device and at the end has a "\".

I have secure boot disabled. (yep, I have an option for that). So now I am left empty handed and I am stuck with Windows 8. I even put in a brand new SSD hoping I would install W7 on it but I can't even start the setup!! Argh....

I am very experienced with MBR and BIOS but I am a complete newbie to UEFI. I don't know what is going wrong and why the setup hangs....Ther... Read more

Hello,
My Dell computer did not boot anymore. Nothing seemed to work, so I went to a friend and copied the emergency disk on a USB drive. The drive seems to work as it installs windows 10, but if I leave it in when it finished installing, it will do it again. I tried taking it out, and the black screen showed a blue window with little balls circling and the words getting ready. Well, I waited quite a while and nothing happened.
So, I started searching the web (I also have a Mac computer) and people seemed to say that I should change the booting bios and disable secure boot. I went into the bios, or so I think, but clicking on f12 at restart. I went to boot but I saw no secure boot in the choices.
I am at a loss here. I haven't used my dell since February, as that is when I had the problem. Then life happened and I did not get back to it till now.
I would appreciate some help if at all possible.
Thanks

Recently I played around with dual booting Linux Mint on my system. I decided that I would delete it for the present as I have other things to focus on. However, after deleting partitions and fixing my MBR to only boot windows my UEFI BIOS still has instances of Ubuntu as a boot option. Just for the sake of cleaning my system I was hoping someone could help with this.

My Motherboard is an ASUS M5A97 LE R2.0 with a UEFI BIOS. I'll provide screenshots of what's happening below. (Images were flipped upon upload for some reason)

As you can see there are two ubuntu options for some reason.
I tried to see if BCDedit would allow me to delete these but they didn't show up in BCDedit
I'm not sure where else to look to delete these options in my BIOS.

Thanks in advance for any help

Hi, can I install a Windows OS normally if I have UEFI or is there a different procedure? By normally I mean what I always did which was: boot from installation disc, follow steps, format (if necessary), click next, next, etc. I ask because I'm building a computer for the first time in a long time and last time I installed Windows 7 it was done like that, but I'm guessing my motherboard was BIOS and not UEFI. Maybe there's absolutely no difference, I just want to make sure and learn.

Also I should point out I've researched quite a bit but I'm still really not that well informed in the differences between BIOS and UEFI or what they are, although I understand they are similarly different firmwares that help communicate with the OS and all the other components. But what is the difference between UEFI and BIOS and how do I know which one I have, does it come with the motherboard? Is that how i can tell? Sorry if things don't make sense, I'm a noob.

Answer:ssd goes missing on uefi bios after indows 7 install

Unplug all other HD's and peripherals,

Boot into BIOS setup, reset to defaults, save changes. Leave overclocking turned off. (If an EFI BIOS you'll need to decide if you want UEFI BIOS vs. Legacy BIOS. If UEFI follow these special steps for Install, otherwise enable Legacy BIOS or Compatibility Support Module to proceed with normal install.) Set DVD drive first to boot, HD second, set SATA controller to AHCI, Save changes and Exit.

Then boot into Windows 7 installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here.

At first installer screen Press Shift + F10, or enter System Recovery Options to open a Command Box, type:

DISKPART
LIST DISK
SELECT DISK 0 (after confirming Windows 7 target HD #)
CLEAN
CREATE PARTITION PRIMARY
FORMAT FS=NTFS LABEL="WINDOWS 7"
ACTIVE
EXIT
EXIT

Next click Install Now, then Custom install to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt. You are creating the partition here for the purpose of wiping the HD and marking Active which overcomes certain install failures.

Hello,
Recently assembled a brand new PC using the asrock Q1900DC-ITX Motherboard. I have a brand new Samsung 850 SSD 120GB, 4GB ram, etc.

I have a Windows Enterprise 64 bit ISO file. The Motherboard is UEFI. I followed the step by step directions in the UEFI tutorial. I used Rufus on a 16GB flash drive. All went well.

I made the adjustments in the BIOS to boot to the UEFI USB drive, restarted, then windows begins to install. Problem is, I only get through the 2nd step where Windows is beginning to install (with the green check marks etc). I then get various errors including 0x80070057 and this one most often 0xC0000005 - verify installation sources are accessible.....

I also tried using the Windows 7 DVD download tool to create a bootable DVD......same issues. I do on occasion get a "memory management error" during the attempted install and the pc restarts itself mid way. It seems as if the pc just restarts if I let it sit for a period of time during the very early steps of the install/

Ive been trying various things over the last 3 days with NO luck. Any suggestions? Also, will a bootable windows DVD work in my situation (with UEFI BIOS)?

Im getting desperate lately

You can install 32 bit to an EFI BIOS but it has to be in Legacy mode, with EFI Boot disk removed from the BIOS Boot order, and the HD wiped with Diskpart Clean Command so installer can reformat it from (EFI formatted) GPT disk to the normal MBR disk.

There are other ways, but you may not be able to boot properly and you need to make a repaor. So the first suggestion is preferable.

so the only way i could figure to boot from media at clean install was to boot from legacy mode.... is there an "easy" way to swap the boot from legacy to uefi? i'm only asking because it takes about 3 minutes to boot from legacy instead of 20 seconds and my ssd drive is missing??

Answer:Legacy bios boot vs uefi

First of all, which media are you booting from? What is your OS?

Hi, I recently fomatted my hard drive and reinstalled windows. In the process I got rid of the 'unecessary' partitions. One of them was the mbr partition. Yesterday I went to the bios and set it to uefi boot up. Of course now the computer does not boot up because the partition is missing. The boot Manager is has an empty list... I am not sure how to proceed Is there anyway for me to get out of this mess? Can I use an external hard drive to boot up the computer and change the bios settings or boot up from an externbal hard drive and reformat the disk but this time set a mbr partition. Please helpSeb

I don't have the option in windows to boot back into the UEFI setup. In my motherboard bios setup there is an option which allows for the selection of UEFI, Legacy and UEFI or Legacy, When I change this to UEFI my pc wont' boot and the error message is that no UEFI partition was found.

I think it may have been deleted when I installed Windows 8.1 initially because i had to convert from MBR to GPT. Or so i read on one of the forums.

Is it possible to restore my UEFI partition so that I can use windows to enter the bios setup. I've had the boot on ultra fast and it took me a week to get into the bios without using the delete key. I had to use Gigabyte utilities which include drivers that crash windows. So i want to remove them again ASAP.

Any help appreciated.

Answer:UEFI option instead of Bios boot

Well to get back into UEFI mode you will have to reinstall in UEFI mode there is no other way, Sounds like some how your OS got converted to MBR so It may not boot either MBR or UEFI but you can't convert back to UEFI you have to Reinstall. If you have data on that disk you need to recover you can pull the drive and hook it up USB to another computer and recover your Data.

Dear Bleepers,
 
this is our strange situation:
My friend has a samsung laptop Ativ Book 2 (np270e4e) with windows 8.
After few problems when updating to 8.1 (it deleted the o.s and gived only a bsod saying that there is not any os installed), she decided to buy and install windows 7 so she disabled the uefi, setted the legacy mode and the boot priority first to the usb hdd (we have a bootable iso).
Parphaps every time we restat doesn't boot from the disk but showed the windows 8 bsod. Naturally the f4 for restore gives anoter bsod for not founding any partitions!
We discovered that it's not possible to boot from the disk, so we made a bootable usb driver with the official iso.
After that we picked up the hard disk and delete all partition from another pc and disabled all the boot driver but the usb hdd. After that it booted from the pen drive with official w7 iso.
The installation was completed in about 30 minutes. We started to install the drivers, chipset, intel storage but:
the next reboot it showed this message: all boot options are tried. press f4 key to recover with factory image using recovery or any other keys for next boot loop iteration and it was a continue loop and can't access the bios.
Strangely when the usb driver with the official w7 iso was inserted it said: "press any button for starting with usb driver"  and if we don't press anything windows started normally.
So we tried to install another time thinking it was a driver conflict but the second ti... Read more

Answer:All boot options are tried, no (uefi) Bios

Seems to be a common problem with Samsungs. See this thread and the post by François.  Can you access the boot menu by tapping F2 instead of holding it down? See if you can access the computer with Fatdog64. You will need to burn the iso file or use Rufus to create a bootable USB. If the USB does not boot then use GPT as a partition scheme in Rufus. 
 
According to here F2 is the boot menu for a Ativ Book 2, 8, 9 but F10 is the UEFI access key. Try tapping F10 at boot.

Belarc reports UEFI: American Megatrends Inc. P11-B2
Operating System: Windows 10 Home (x64) Version 1511 (build 10586.494)
Installed: 4/27/2016 5:58:22 AM Servicing Branch: Current Branch (CB)
Boot Mode: UEFI with successful Secure Boot.

This is my brother?s computer: originally it was Win8, upgraded to Win8.1 and then in Apr to Win10.
--- The computer runs OK and I?ve shown him how to use MRF to create system image backups.
--- Today Aug 8 we tried to test recovering yesterday?s Aug 7 system image backup.
--- It didn?t go well at all.
--- The MR recovery DVD-RW didn?t boot up in order to test it.

I thought of disabling Secure Boot to see if that was blocking the MR bootable Rescue DVD-RW.

However we weren?t able to boot into either the UEFI BIOS or Boot Menu.
--- According to our notes DEL is used to boot into the UEFI BIOS and F12 is for the Boot Menu.
--- However when booting up: in less than a split second something scrolls up but the computer immediately boots into Windows to log in.
--- That?s much too fast to get into the UEFI BIOS or Boot Menu.
--- Please help us figure out what to do.

Following that I?ll have to learn how to ensure proper system image backups and recovery using MRF.
--- I don?t recall any issues when I had Win7 but re-training myself makes sense to me because it?s obvious I don?t understand it well.
--- For now I?m going to completely uninstall MRF from his computer and hope to start over with a clean slate.

Answer:Cannot boot into UEFI BIOS or Boot Menu

Try F2 or F8 while Powering ON.. (which you might already Have). If no go update BIOS(which you might already have).

Assuming you have Windows 10 or Windows 8.1 on computer.. Do a Shift + Restart >> Troubleshoot >> Advanced Options >> Change UEFI firmware settings...Restart.

Hello, currently I have the upgraded Windows 10 Pro Spanish 32-bit activated from Windows 7 Spanish OEM 32-bit on a 2011 HP ProBook 6550b LATAM which I guess has the digital entitlement since no keys were entered. I would like to clean install & format the drive using the USB Windows Pro 10 media & Brink's Windows 10 - Clean Install tutorial and have 3 questions:

Q1: checking in System Information is says the OS was installed in BIOS Legacy Mode but in the Boot menu there is an option to select UEFI instead. Which one is the best?

Q2: if clean install is done with an English US version instead of Spanish will I loose the activation?

Q3: I tried changing the display & speech language option to English in my current Spanish OS, rebooted several times and get the persistent Windows Search "these results may be incomplete" error after Indexing is completed as reported in other threads while it works fine when reverting back to Spanish display mode.

Will it be possible to boot Windows 8 from a GPT partition using BIOS (not UEFI)? I'll be using the 64bit version.

Technically, I know it's possible as I'm doing it with FreeBSD, many Linux distros etc. Using hybrid MBR/GPT, I've read others have Win7 booting off GPT partitons as all. I'd rather not go that route.

Answer:Boot Win8 on GPT partition via BIOS (not UEFI)

I am pretty sure you can't do that with Windows - not unless MS have changed something without announcing it.

Hello All: I have a most perplexing problem related to the UEFI boot process. Recently, I completely rebuilt my W520 4270CTO (from scratch) using Microsoft Win7 Pro SP1 media.  The computer has an Intel 80 MB mSATA SSD (the boot drive, holds the OS and applications), and a Seagate Momentus hard drive (coincidentally, the exact same model specification as the computer shipped with, but not the actual OEM drive) installed inside as the 'D' drive. This drive holds the user profiles and data. I have configured the computer BIOS to do a UEFI boot only.  I have also set up the boot order in the BIOS so that the Intel 80 MB mSATA SSD is the very first item in the list, and the 'D' drive is second.  The 'D' drive has no OS. If I start up the computer from a cold shutdown, it boots very quickly, everything is just wonderful, it is the world's fastest computer.  But... If I leave my two external hard drives plugged into the USB port (my 3 TB drive plugged into the blue USB port on the side of the computer, and my 1TB drive plugged into the yellow USB port on the back of the computer), well, forget about it... the computer won't boot, it presents me with the Windows Boot Manager screen, and even if I manually select the mSATA SSD (which is at the top of the boot order), it won't boot.  The only way I can get it to boot is to unplug the two USB connectors. What is most ironic about this is that the 3 TB drive is empty, except fo...

Have you tried to use Acronis or Ghost 15? I do not use the Windows Image Backup because it requires a 1 to 1 correlation when and if you need to restore. Ghost 15 supports AF disks natively and can perform image or incremental file backup. I highly recommend it. BTW, I see that you did not install the System_DRV partition on the SSD? I know that it isn't required if you do not use a Boot Manager, but I thought that UEFI was a boot manager as well.

The problem is that on startup it's impossible to start GRUB, Windows is loaded automatically. Is there a way to change UEFI boot order? I tried several methods but Windows always overrides my changes; I managed to load GRUB only once by renaming the Windows OS Loader path to the GRUB one, but after I booted to Windows once again, it overrode my settings creating a new Windows OS Loader entry. These are the methods I've already tried: Renaming the path as I said up here through bcdeditUsing EasyUEFI to change boot orderUsing efibootmgr in KubuntuUsing boot-repair in KubuntuUpdating GRUB in Kubuntu While on my desktop I have a BIOS setting that lets me change UEFI boot partition, I don't have anything similar on this laptop. Let me know, thanks.

Greetings Acer community; After purchasing an Acer Aspire E1-510 laptop for my wife with pre-installed Win 8, I've been through both a journey and learning process about the old MBR BIOS and the new UEFI BIOS.1: The two are, apparantly, totally incompatible. You can not boot from a UEFI BIOS onto an older MBR boot hard drive, USB stick, or CD/DVD drive, although Windows will read and write both MBR and GPT disks as data.2: UEFI has many 'features' the old MBR BIOS doesn't like 'secure boot', support for large hard disks over 2 gigs (up to 128 xabytes in Windows).3: UEFI is suppposed to be a better, more modern BIOS (which may be true eventually), but right now, it is apparently poorly implimented - see the many criticsms on net, especially from the Linux community.4: UEFI has the potential to be abused by OEMs - that is: they can impliment setups that lock in certain OSes (Windows on the desktop for instance), while cutting out alternatives (Linux for example).5: UEFI is a modular, extensible, BIOS that can, in theory, make all devices more secure (blocking root-kits for example) while NOT substantially affecting 95% of users computing experience. Problems can become huge for the other 5% of us who like to tinker, install 2 or more OSes, and generally modify our software implimentations on various hardware (i.e. make it more functional and to our liking). It's like what the NSA claims when they spy on us. If you want more security, you have to give up rights, privacy, and fre... Read more

Heys guys, I'm hoping I can get some help with this. I have a Lenovo y410p. It has 2 drives, one with the OS (120GB SSD 40mm N.2 NGFF) and a data drive(1TB HDD)
My computer recently crashed when I was installing a piece of software, (Bentley MX Road, it's a road alignment package.) When I restarted my laptop I was greeted with a lovely message informing me that winload.efi was corrupt. That was fine so I did a bit of research to fix it involving getting a recover DVD and going to the command prompt to rebuild BCD. That didnt work for me as it didnt detect windows. I tried to see what was up with the SSD using DISKPART & CHKDSK. Neither of these showed the SSD. They only showed the HDD
So now to take a step back, In order to get the recovery DVD to boot I had to change the boot option in the BIOS from UEFI to legacy support. This showed me a list of bootable devices (HDD, SSD, DVD etc.) When UEFI is selected only one option is available which is the Windows boot manager. This is followed by the serial number of the HDD which does not have any OS on it.
I have tried using f12 which give me the windows boot manager option and nothing else. When I select this, it boots me into the error message.
So to get to the root of this, how can I change the boot order when the BIOS is set to UEFI so I can repair the winload.efi file on the SSD. Thanks for any help.

Answer:Changing boot order when BIOS is set to UEFI

You change it the same way as before. Usually you can do it withe the OEM software installed on Win8.

You may have to turn off Fast Boot if set.

Have you got the SSD plugged into SATA port 0 on the motherboard as it boots from port 0?  I added an SSD to my H30 - I initially put the SSD on SATA port 2 on the motherboard, port 0 was the existing HDD and port 1 was the DVD drive.  After cloning the existing HDD to the new SSD I swopped the SATA cables on the motherboard so the SSD is now on port 0 and the HDD on port 2.  It booted fine from the SSD even though the existing HDD was still a system drive.  For info I then re-partioned the HDD into one partion for a data drive and pointed my user folders (documents etc) to the HDD.

Hi all,

I have just recently installed Windows 7 on the Plextor M6 Pro 128GB SSD. Everything went fine for the first few boots, and Windows will not boot up after that. The computer automatically goes into UEFI BIOS as if there is no Windows installed on any of the hard disks.

I removed the SSD and inserted it into the external enclosure and hook it up to my laptop via USB. Windows (on my laptop) did not show any removable media under My Computer. Upon firing up Disk Management, the following screenshot (Screen1.jpg) can be seen.

I humbly seek for advices of anyone out there who might be able to help me regarding this issue. I have previously successfully installed Windows 7 on all my older PC/Laptops. But this is the first time I have installed it on an SSD. My previous installation on HDD works well without issue (used it for 6 months before I reinstalled it onto the SSD). I ran into this issue twice within the same day (I reformatted and reinstalled Windows after my first encouter).

I will post whatever details required to solve the above issue. Also, any explanation and information regarding the issue as well as how to prevent it from coming back would be very useful.

Many thanks in advance!!

Answer:HELP!! Windows 7 on SSD failed to boot, goes into UEFI BIOS.

Hi there

In all cases ensure LEGACY BOOT is enabled if that option exists in BIOS.

1) First ensure PROTECTED BOOT is DISABLED -- this doesn't mean turning off UEFI.
2) Ensure the SSD is formatted to GPT and NOT MBR
3) Ensure your W7 install media will handle UEFI boot and install.

If you Don't want to use UEFI boot

1) Disable UEFI in BIOS.
2) Format SSD as MBR
3) Install W7 - default mode will be non UEFI.

Cheers

Yesterday, I had trouble in device one of my friends

Is a new device, there it type of MB GIGABYTE Model "ga-p61a-d3".

When I tried to do I install Windows 7 via flash memory after the first screen choose your language and then show a message that the agreement does not exist any Drive.

I enter the BIOS and try disable UEFI bios or change to legacy mode but same thing. and try disable CSM also the same thing.

I got to bring windows CD and install Windows normally.

After a search today I found it to be make a flash memory with another program to working on that type of Bios.

My question is: If I make a Flash Memory by program "refuse" to work on UEFI BIOS will work on all devices or devices with this type of bios only.

And if the answer is not possible Is there a way to make it work on all devices with the old BIOS and the UEFI bios.

I recently purchased an Inspiron I5 5567 which came with win 10 home edition. I wanted to replace this with win 10 pro which I already have a retail version on dvd available. Ideally I want to install this using the uefi bios but when I attempted to do this, the install only worked as far as the first reboot at which point some dell diagnostics kicked in! As part of the installation process I had removed all the existing partitions on the hard disc. Subsequently the uefi bios will not recognize the dvd drive. I have been able to install the os using the legacy boot options bit this isn't really what I want. I'm quite happy to trash this and start again but when I try to boot in uefi mode all I get is "no boot device found". I'm guessing I need a different iso that supports uefi but I've no idea how to proceed. Can anyone point me in the right direction?

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...

I have a 250GB GPT SSD and installed Windows 10-64bit in UEFI mode.

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.

Asus G73sw Laptop that I have used every day for the last 2 years.

So, I got the message: "Reboot and Select Proper Boot Device, press any key" so I tried another working HDD that has windows 7 on it; same message. I took apart the computer and checked the connections and cables. One time, during the constant restarts with other HDDs, I got the message "A Disk Read Error Occured." When I entered the BIOS menu, It recognized the HDD. Also, on the Easy Flash, I could see that HDD and its files.

Finally was able to load windows with UEFI mode. I am unaware what this is, but I assume it will work for now?? I have made no updates to windows 7, installed no drivers or programs recently, and am unsure why BIOS won't load any of my HDDs to windows, when BIOS clearly sees it.

Can anyone help me with this issue?

Thanks

OK, you cannot take a hd with windows already installed and put it in another system then expect it to boot. Not going to happen unless the two systems have very similar or identical hardware.

This allows windows boot mgr to take over the boot process. This is not the only difference; there are many. UEFI uses GPT table, can address larger hd, and a lot more. Here is an article that explains uefi in more depth;

So I have a 100-15iby that's out of warranty, so I decided to try Linux on it (works great, unless you leave it doing a distro upgrade overnight and a power outage happens and the battery dies, requiring a reinstall) So I go to re-install and I try and boot from the USB, and it says "Boot from USB <Verbatim Store-N-Go> has failed".  This raised an eyebrow, and I thought it might be a bad thumb stick, so I try another, a Kingston drive. I load up the boot menu and the option for USB says "EFI USB <Verbatim Store-N-Go>", which is weird because any other time I've tried to boot from this Kingston drive it said the name of the Drive next to the USB option. Tried to boot using Legacy mode, but that only brought up the UEFI boot menu, it was at this time that I noticed that the UEFI Bios isn't saving settings.  So I take the laptop apart, pop the CMOS battery out, hold the power button for 15 sec to hard-reset, then power on/off for good measure, put the battery back in, closed the laptop up and powered it back on. And the Settings were still there! GRRRR... It still boots into Windows fine, so I know the laptop is working, so at this point I'm thinking the CMOS battery is dead (which if this was the case, I should have been able to clear the settings, but no dice), or there's something wrong with the Bios or Mobo. I can't revert the Bios because the setting for allowing a reversion is disabled and can't be enabled to al...

Wanted to try the UEFI so I deleted my legacy BIOS/MBR installation of Win 8.

I followed the steps here:
UEFI (Unified Extensible Firmware Interface) - Install Windows 8 with[2]=Installation%20and%20Setup

Got Win 8 to install successfully in in the UEFI/GPT way.
But after restart on installation done, the PC cannot boot into Win 8 and I always get the light blue screen with a "Recovery" title stating that the PC couldn't be started properly and an error code 0xc00000001.

Played with the BIOS setting (CSM, Secure Boot etc), switched to onboard graphics, reinstalled a few times the UEFI way.
Also tried the automatic repair but to no avail.
The UEFI installation is always successful but I always cannot boot to Windows.
What different is that the installer always partition the drive to 4 partitions (Recovery, ESP, MSR, OS) instead of 3 in the tutorial.

After hours of trying to get it to boot UEFI Windows 8, I gave up and went back to install via legacy BIOS/MBR.
And here I am posting this in Windows 8 (legacy BIOS/MBR).

If possible I would like to get UEFI working, are there any small details I missed?

At any point in the future, is a new BIOS/UEFI firmware going to be released that unlocks the selection for "UEFI" on the boot mode? I have an operating system/bootloader that would be better served with the ability to switch to a legacy BIOS style mode as opposed to being locked into UEFI only. Consider this a formal request as well, to include a legacy boot mode in a future release. I know there's quite a few of us who would consider this a very useful change.

Hi all. I have had nothing but issues, since upgrading to Windows 10 from Windows 8 (64).
The installation within of itself was horrible.
I got the continual flash on the screen, until I was able to get it into safe mode and recovered it.
Then made sure drivers were updated.
However, I did not upgrade my BIOs, from the information I had seen from MSFT.
Didnt think twice, since they said if you were upgrading from 8 or 8.1 that should not be an issue.
The system was running stable, after I did those fixes.

About 1 week ago, after a MSFT Windows automatic patch push, My monitor started not to respond during boot up. Ran some basic troubleshooting for the monitor (Ie: check plugs, check cables, check Video card).
They all seemed to work fine and my system booted up normal.

The very next day, cold booted again and monitor did same thing, it was not getting any signal from the computer.
Went through the checks, after a little bit of a delay the system finally booted.
I checked my BIOs settings, which were all set up normally.

I locked my computer after that and did not turn off the system, the next morning, my monitor was unresponsive.

I re-checked monitor, cables and even replaced the video card. Everything is good except no signal to my monitor.

Answer:Computer wont boot (even into UEFI/BIOS) after Windows 10 upgrade

Do you believe that the Windows 10 upgrade corrupted your BIOS, or otherwise damaged your hardware? That would be unusual.

What do you mean by "bootable USB BIOS"? There are a variety of things you can put on a USB device, including a DOS environment for doing a BIOS update, but "USB BIOS" means nothing to me.

When you "disconnected all hardware except the video card and motherboard" did you also disconnect the hard drive and the opticals? I once fried an internal Zip 100 drive, and the PC wouldn't boot with it attached. (It was probably an IDE device, though. Long time ago.)

I'd like to blame Microsoft for your troubles, but I just don't see it.

So, I got a Inspiron 3537 i5. Nice laptop for it's price. Downloaded all the manuals, made my recovery DVDs. All was well in my world.
First thing I noticed is that there is no info in the manuals for tweaking the BIOS and since it is my first experience with a UEFI bios I was a bit disappointed. Is there a manual available for it?
Next I upgraded ATI Drivers to 13.12. I am an old user who always knew that updates were usually a good thing to do. Got in the same problem as many others with PC screen not waking up from sleep.
Thought I would do a recovery from the disk, but after trying various combinations (Ctl+F11, F8, F12 etc) I couldn't find a way to boot in the Recovery console. I did the recovery from my DVD and the laptop works fine.
Does anybody know how to add in UEFI bios a boot option to the Recovery partition? I undersstand that I have to create a new boot option using "Add boot option" and the two options available are to boot to the 1st (windows EFI) or 2nd (recovery partition), but the path for the recovery efi file to be loaded is unknown (+ you can't have access to the recovery partition to see the contents of it from windows). Any suggestions?

I have an Ideapad Z585. My hard drive is having problems (won't boot), so I want to boot from a DVD or USB. Problem is, when I change the boot order in the BIOS (UEFI) to put the optical drive ahead of the hard disk, that setting won't save (although others do). When I exit the BIOS and look again, the boot order setting has returned to the original (hard drive first) setting.  **bleep**?? This means that if my hard drive is present, it will ALWAYS be used to boot from, which of course ALWAYS fails. There is no way to fix the hard disk because I can't boot anything else. This is a serious bug in the BIOS / UEFI.

The preinstalled OS works, but i have tried to intall windows 7 and ubuntu, both 64 bits.The problem is that i can't get them to boot with the UEFI mode on, it works great when i switch to legacy mode.When i boot ubuntu it just gives me a black screen, and Win7 hangs at the Starting windows screen, When i try to install win7 in safe mode it hangs at "Loaded: \windows\system32\DRIVERS\disk.sys" On the bios, i disabled the secure boot, changed the SATA Controller mode to Compatible (read somewhere it could help)  and changed  "OS Optimized defaults" to "Other OS" I don't want to install in legacy mode because i would have to reformat my entire hard drive and losing win8 and the recovery partition and also i would really like to use the "advantages" that UEFI offers. Anyone got a similar problem?

Answer:Can't boot/install any OS in UEFI mode

Hello and welcome,
 
Are you trying to boot from CD/DVD?  I've been able to boot both Win 7 and Ubuntu 12.10 in UEFI mode - although on a different model laptop - by using a USB flash drive.
 
The Ubuntu flash creation is pretty simple: just create a flash drive with a FAT 32 partition and extract the contents of the Ubuntu ISO to it.  You don't need to "install" to the flash drive, just copy the files.
 
If you actually do the Ubuntu install, elect to have grub installed in the Ubuntu parition (whatever that means in a UEFI install...).  You should then be able to select the OS to boot via the UEFI boot manager, not grub.  The Ubuntu installer garbles the Win 8 entry in the grub config and it (win 8) won't be bootable via grub anyway.
 
Win 7 is a little trickier.  More or less the same process, but after extracting the ISO (or copying the contents of the DVD ???) some fiddling is required: Installing Windows 7 in native EFI mode from USB
 
That said, I have to stress that I've only done this on a Twist, not a Y500.  You run the risk of hosing your Win 8 installation.  Don't run the Linux boot-repair app, and don't restore BIOS to defaults after an OS install.  You'll probably lose the UEFI boot entries.
 
I was able to install Ubuntu 12.10 dual-boot with Win 8.  The Win 7 install was stand-alone, and I didn't try to multi-boot wiht Win 8 or anything else.
 
I don't speak for Lenovo, the above ... Read more

Have a new Dell XPS 8920 Desktop with a 256 SSD and I want to install a 2nd Win 10 operating system on a 2nd drive under UEFI. If I do a clean install from a DVD will the 2nd drive be seen and bootable?

Hey all,

I just got a new HP ENVY dv7t-7200 CTO Quad that came pre-loaded with Windows 8. I wanted to install Windows 7 so I enabled "Legacy Support" in the BIOS which disabled UEFI mode. Everything went fine from there. I ultimately decided to go back to Windows 8.
I found this guide but could not get my Windows 8 installation that I have on disc to load on startup: UEFI (Unified Extensible Firmware Interface) - Install Windows 8 with
I disabled "Legacy Support" in the BIOS so now UEFI mode is re-activated.
My UEFI Boot Order in the BIOS is:
CD/DVD Rom
USB Drive
OS Boot Manager

But when I have the disc in and restart windows, it does not read the Windows 8 installation from the disc. If I press F9 to change the Boot Order it only shows:
OS Boot Manager
Boot from EFI File

It should be noted that the it will recognize the disc if I'm not booting in UEFI mode.

I could install Windows 8 again without UEFI but I would really prefer it. Any suggestions?

Answer:UEFI cannot boot from USB or DVD to install Windows 8

Solved -I went to System Recovery while starting up by hitting F11, then used the option to restore the comp back to factory settings. It installed Windows 8 in UEFI Mode
