I followed these steps :

1) In BIOS/UEFI set the 1st drive to UEFI even though nothing is there (it makes a difference, I tried it without doing this and got an error)
2) Set your optical drive with Win 7 CD as #2 boot drive
3) Run Win 7 install and when you get to the initial screen, hit Shift - F10
4) Run diskpart.exe
5) Before you run "convert gpt", use the "clean" command to remove any data and configuration files. I assume if it's a new disk this won't be necessary. Do it anyway just to be sure there aren't system files on there.
6) "exit" 2 times and start the Win 7 install program
7) Run Custom Install - Advanced Options and it will show one 2.8 TB partition.
8) Select "new" and it will create 2 systems partitions and one new partition that is 2.7 TB
9) Only format the 2.7 TB partition, the other 2 were already formatted when Windows created them. If you format them, you will remove the system files that Windows put on them and you will get an error on installation.

When I didn't use the "clean" command, Windows reverted back to the MBR set up and gave me an error saying the drive must be GPT not MBR. Even though I ran the "list" command and it showed that the drive was a GPT drive, it still reverted back to MBR. I assume it did this because there was still data/configuration files on the drive from the system files Win 7 added when I was trying to format the drive prior to setting it to GPT.

And......there it is in My Computer, a 2.72 TB C: drive.

And ..... there it is in Disk Managment a 2794.3 GB drive with a status of - Healthy (EFI System Partition), thanks to John_Vankirk above I knew how to get there.

1) Click the Windows start button (lower left screen), enter "command" in the "Search programs and files" search box
2)Enter diskpart.exe
3) Enter "list disk"
And.......there it is, a 2.794 TB Disk 0 with the GPT column checked







But Nothing Happens!! When i click new, i see only the basic partition and ONE system partition.

Also when i go in windows the list disk dont work, and in computer ---> manage, i cant see uefi, neither in msinfo32, neither in windows ---> partner folder. It says detected boot environment : BIOS.

What can i do? My mobo is Asus H81M-E, it support uefi, also i can use bios with my mouse. Is this UEFI?

When i select from bios boot only from uefi, it gives an error..

So much confusing!

My ssd is samsung 840. WIndows 7 in one desktop and Windows 8.1 in other.

What i do wrong?




You say : In BIOS/UEFI set the 1st drive to UEFI even though nothing is there (it makes a difference, I tried it without doing this and got an error)

But i cant see this option. Only ssd and cd option.

After 10 hours i did it. I made a bootable usb and i managed to run it as uefi boot.

What was wrong with the dvd, i dont understand..

Now i enable secure boot? A watermark appeared in my desktop, that says secure boot isnt' configured correctly.
