Cannot install Windows 7 to GPT with UEFI boot - Page 2

post #11 of 32
have you tried Windows 7 x64 installation media? it will work with the same product key as 32-bit you have. just asking, because I think the installer in 32-bit mode is a problem here, just like it was with Vista 32-bit (no GPT boot).

another thing, what is your video card? AMD by any chance? I think those do not support UEFI ... nvidia 700 series does natively and 600 series can be updated to UEFI GOP after you contact vendor technical support for an update.

The media I am using is 64bit, copied DVD over to a USB that was made bootable.

I am using an Nvidia GTX 760.

If you did a straight copy, you need to do this step:
Warning: Spoiler! (Click to show)
2. Your USB drive must also contain the directory and file: "*:\efi\boot\bootx64.efi" (* is the drive letter of your USB key that holds the Windows 7 installation files). This is the ".efi" installation boot loader extension. If you do not have this directory or file on your USB drive this is how you create it:
First, create a new directory called boot inside the "efi" folder on the USB.
You will then need to copy all of the files from the "*:\efi\microsoft\boot" directory into the directory you just created ("*:\efi\boot").
Next, use 7-Zip to open the archive located at: "*:\sources\install.wim."
Inside the archive, find the file located in folder "1\Windows\boot\efi\bootmgfw.efi."
Copy this file to "*:\EFI\Boot\" location you created earlier. (Not in the 7-zip) (This file is also available from any current windows 7 installation. It is located in the "C:\Windows\Boot\EFI" folder.)
After copying the file to the "*:\efi\boot" directory, rename the file in "*:\EFI\Boot\bootmgfw.efi" to "bootx64.efi". You should now have an EFI boot loader folder for Windows called *:\efi\boot\" with all of the files copied from the "*:\efi\microsoft\boot" folder and the newly named "bootx64.efi."
Your install media (DVD/USB) must be inserted into your PC prior to powering it up. This will allow your UEFI to register your device (DVD/USB drive) as a UEFI boot enabled device.

Thanks, I will give that a shot. That's a lot of craziness involved for supported drive type!

yeah, there is extras step involved in moving efi boot loader file up one directory from under microsoft/boot to boot on USB stick, it should go through after that.
it must have been reverting to MBR boot since UEFI boot loader was not present on USB stick.

had that same problem with WIn 8 x64 USB stick (created by MS tool, it didn't do that step automatically).

EFI boot loader files moved over, renamed, etc.

Boots properly now, and allows me to do a GPT partitioning!

Thanks all.

Hi

I have similar problem. I have Z77X-D3H Gigabyte motherboard with latest bios. I have 4 TB seagate disk and I have activated UEFI boot everywhere I saw it (UEFI only, UEFI First). I have created USB boot key using RUFUS tool (http://rufus.akeo.ie/). This tools is specialy designed for creation GPT UEFI boot USB.

I have dropped all partitions but still I "cant install windows to this disk" - in detail is displayed message that my BIOS controler maybee doesn't support booting from this this and I should enable it. But where ? UEFI is enabled in BIOS everywhere.

I have tried to use also DISKPART and clean disk, convert to GPT manually => no chance. Still "cant install windows to this disk". Horrible !!!mad.gif Help !!

PS : two days ago I have managed it somehow and I was success to instal windows to GPT, but now everything is useless. I do not know what to do. Its too complicated.

have you tried removing all partitions from that disk and letting the installer create them on empty space? it should do that easily if it is truly booted in UEFI mode, that's what I do ...

Hi, thanks for feedback , I'm sure that I deleted all partitions. Im 100% sure that also everything was set to UEFI in BIOS and I have created correct USB key. Im afraid that this is issue of my gigabyte Z77X-D3H motherboard. In the past when I really needed MBR I had a problem that always UEFI was installed instead of MBR. Now when I really need UEFI I can't manage it ( on the same motherboard, disks , etc...)

I heart that after installing windows with GPT, this device shoud be immediatelly vissible in BIOS as "UEFI : DISKXX device" in boot manager. This is not my case. Still Im receiving error : "Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu."

I have tryed to install it as AHCI, RAID , but still same result - everything set to UEFI ONLY or UEFI FIRST. And it was working for me in the past ! Gigabyte ??!

Meantime I gave up. I have created RAID 0 with my 2x 4TB disk - first volume with 120 GB for MBR and system and rest of space for GPT. - my system is working now but only with MBR.mad.gifmad.gifmad.gif
