I am trying to install a Windows 7 x64 Home Premium in UEFI mode1. For this purpose, I obtained a DVD from the vendor of my computer that contains all editions of Windows 7 x64. (The Microsoft Win 7 ISO download site does not work for me because it refuses to accept the (OEM) product key found on my computer's certificate of authenticity, hence I cannot download from there – Microsoft recommends to ask the PC vendor for a disk instead, which is what I did.)
According to some resources such as this article (only in German), Windows 7 x64 DVDs are already prepared for UEFI installation. Also, the article says I need to enter the UEFI boot menu upon booting while the Windows DVD is in the drive. The UEFI boot menu should then show two entries for the DVD drive, one labeled "UEFI" for the UEFI boot.
I can enter the UEFI boot menu. Unfortunately, I see only the following entries ("…" means I skipped some detail information that only consisted of letters and numbers and probably does nothing to illustrate the issue):
- UEFI Default
- SATA2:HL-DT-ST DVDRAM …
- Generic-SD/MMC 1.00
- Generic-Compact Flash 1.01
- Generic-SM/XD-Picture 1.02
- Generic-MS/MS-Pro 1.08
- Realtek PXE B01 D00
- Enter Setup
So, the DVD does not show up in UEFI mode; it just shows up once, in normal mode.
As far as I can tell, secure boot is disabled in my MSI UEFI BIOS. (It looks like this, and the entire Windows 8 feature group that contains the secure boot feature is set to disabled.)
From superficially looking at the contents of the installation DVD, it looks like it is supposed to support UEFI boot:
- There is a
bootmgr.efifile in the root directory.
- There are some files in a
efisys_noprompt.bin, as well as a
Am I doing anything wrong in the UEFI boot manager while trying to launch the setup? Or is my Windows 7 DVD not actually fit for UEFI boot – in which case my question becomes: Can I create a modified bootable Windows 7 setup medium based upon the DVD I have that actually can boot in UEFI mode?
1: My actual objective is to make use of the full 4 TB of my system HDD, which seems to be possible only with GPT rather than MBR, which in turn seems to require installing Windows 7 in UEFI mode.
