Is Windows 7 x64 UEFI install even possible?
Hi everyone,
i joined this forum because i found a lot of interesting information here regarding Windows installations and unattended setups.
I've been in I.T. for 15 years installing windows since 3.1
We now are a a crucial step in Microsoft Windows life where all the computers with USB3.0 support, UEFI only and no legacy BIOS support are not compatible with Windows anymore.
When you try to boot off a USB you get:
\EFI\Micosoft\Boot\BCD error with a status of 0xc000000d
The latest hack i tried from a USB was to get all the Windows 10 setup files but replace the install.wim with the Windows 7 one.
When you do this, the install works and the windows setup files are laid down on the hard drive but after reboot you get the same error.
BCDEDIT doesn't help so the only thing i can think of is to mess around with the OSCDIMG.exe options to create a purely efi .ISO and see if that works.
Just wondering, has anyone here ever gotten this to work?
By the way, the unmodified Windows 7 Microsoft ISO boots up fine in a system where UEFI is on and secure boot is off, but from USB you get that error, which leads me to believe the OSCDIMG might be the key.
Anyway i wanted to get your thoughts and if i get something working i'll post a guide here because this site is useful and might help other people in the future.
Thanks.
