Installation of Windows 7 SP1 UEFI failing
Hello,
A while ago my boss told me I needed a laptop, so I bought a nice second hand one, and bought a fresh new copy of Win7 SP1. It always worked fine, until the laptop died.
My boss bought me a nice new laptop, but we found out that some programs don't run well on Win10. We also have an outdated server setup, and Win10 seems to have some problems with it.
So we decided that I need to go back to Win7 64bit. And I decided to start reading up on that UEFI thing. I double checked that my Acer E5-721 has UEFI activated.
Via the tutorials on this forum I found out that I need a UEFI compatible ISO from Windows. The one I have is not. Apparantly I need BOOTx64.EFI in the EFI folder. Which I don't have.
So I unpacked the ISO, and unpacked INSTALL.WIM to find the BOOTMFGR.EFI file, and copied it to the EFI folder. I then used IMGBURN to turn it all back into an ISO and Rufuc to create me a bootable USB.
But it just don't work. I don't get the Win7 install screen. The laptop either goes to Win10 or gives me a screen that says: "Windows failed to start. A recent hardware or software change might be the cause. Status: 0xc000000f."
I also tried to put the required EFI files into the BOOT folder (seeing as some tutorial I found via Google suggested it). But nothing seems to work.
Can somebody help me to fix this??
