Qubes won't install on legacy BIOS (non-UEFI supported pc)

[cxr...@gmail.com]

My system doesn't support UEFI Firmware, The USB works fine on Rufus but whenever I try to boot from the USB via boot menu it's almost like it doesn't even detect my USB since every single boot device I've tried on the boot menu I see that damn Windows logo every time. I already tried making the USB device the boot priority and that doesn't seem to work. I even tried on a different computer with UEFI settings and guess what? It worked perfectly. It's crazy how my computer is custom built but doesn't have UEFI lol...

Obviouslyt Qubes does install on legacy systems.
Try any live image burnt to USB, and another USB device.
You may be right that it is not detecting the USB at all.

Some of my USB thumb drives are not detected when trying to boot from them, others work fine though.

Also, one of my machine doesn't detect a USB thumb when trying to boot from it in a USB 3.0 port, unless I go to Bios and set the USB 3.0 ports to Legacy mode.

I don't see that option to set USB 3.0 to legacy mode, I believe all my USB ports are 3.0
