Alright. I've been working on this for a week now, and I need to solve this.
So, here's my problem:
I have a Windows 7 USB I just formatted, GPT partition scheme, Fat32 format. I then boot into the USB via my BIOS (specs below) and after the Windows 7 orb shows up, the "Install Windows" menu shows up. No mouse, no keyboard inputs, nothing.
I then go to create a custom NTLite ISO with the following drivers: ASMEDIA and the unofficial Windows 7 drivers.
I make the ISO, burn it, boot from it, same problem. No keyboard or mouse inputs.
Here are my specs:
Z390 motherboard with UEFI on it, Logitech G900 mouse, NPET gaming keyboard, 6 cores, 16 gigabytes of RAM.
The computer has already been in service for about 5 years, getting an upgrade last year, kept the motherboard.
If anybody finds possible drivers, please link them. This has been a problem for 3 weeks.
Thanks for your help!
