Hello Acer Community,
I'm trying to install Wkndows 7 Home Premium 64bit on UEFI. My PC is an Acer Aspire 5 A515-51G-51V7.
BIOS updated to last version (1.21)
Secure Boot disanled.

I've already been able to install Windows 7 under LEGACY mode. I had to inject some files (like USB3 drivers) on the ISO file, or the setup would ask me to look for missing drivers.

But seems I can't install it on UEFI at all!!
What I have tried:
-Created Bootable USB with Rufus, selecting GPT scheme.
When I boot from USB on UEFI, I get a black screen with:
Windows Boot Manager
Windows failed to start. A recent hardware or software change might be the cause.

File:  \EFI\Microsoft\Boot\BCD

Status: 0xc000000d

Info: an error occurred while attempting to read the boot configuration data. 

Then I tried to use WinNTSetup, by first booting from a USB Win8.1 PE. The program install some files on the HDD but then if I try to boot from HDD to start setup, I get the same error as above.

As last, I tried to use the program Easy2boot (it's an alternative way to make USBs bootable) and I converted my ISO to an .imgPTN file, then used the program to boot it.

This time the error disappears, as it shows a black screen with "Loading files.." like it's working. But when it finishes, the "Starting Windows" screen appears, but with no animation, and the setup won't never load.

Does someone know a way to install it on UEFI? Or, is it even possible? Thank you.
