Hi,

I'm trying to install Win 7 from a (know good working) USB flashdrive. The desktop is a USB Pavilion Slimline PC 400-314 with WIN 10 already on it. I've attempted to go into the Boot Menu (using Esc) to access the Boot Menu but I don't see the USB in there (see attached).

Also tried going into BIOS & have made USB Hdd the first but still no luck (see attached). It just boots normally into Win 10. Once in Win10, it see's the USB drive. I tried both the front & rear USB ports. I know the drive is good because because I just installed/booted from it yesterday on another machine.

I've also made sure all USB ports are enabled unless there is some setting preventing a boot from USB?

Any assistance appreciated. Thanks.

As most newer computers do, you have a UEFI Bios. Restart the computer and press F10 to Boot into Setup (Bios) and look for Secure Boot If it is enabled using your arrow and Enter key Disable it or change it to Setup Mode.
Now at the Boot tab, scroll down to Legacy Boot Sources select it and press F10 to accept. With the USB Flash drive in, Under Hard Drive Group, you USB Flash drive should now be listed. or just USB Hard Drive, Select it and Move it to First Boot Device. Save and Exit.
Or, if you cannot make changes in the Bios, Create a Bootable UEFI USB Flash drive with your Windows ISO using Rufus in my signature.
