Need some help. This unit came with Windows 10, but I need to install Windows 7. The UEFI BIOS disables USB Keyboard and mouse support on any setup/boot disk other than Windows 10. The latest BIOS update can be found here (disguised link): httpee://ftpee.hp.com/pub/softpaq/sp77501-78000/sp77848.ex_ Thanks in advance for any help
@geebrond This has nothing to do with bios - integrate appropriate USB drivers in boot.wim & install.wim beforehand,
Waste of time... I injected all the USB drivers from the Windows 10 boot.wim and install.wim to the same in Windows 7, and got the same result. I can boot just fine with USB keyboard and mouse support with a Windows 10, or WinPE 5.x boot disk, but the BIOS automatically disables USB kbd/mouse on a Windows 7 boot. Micro$oft efforts to make Windows 7 obsolete, and force Windows 10 on us, continue.
