This may be a totally useless experience from another Dell computer, but ... I was running an older Fedora on both a non-Dell desktop and a Dell Vostro laptop. I decided to do a fresh reinstall on the laptop. First, used the desktop to create an install flash drive (F34). Forget if I used mediawriter or dd, but should not matter. The flash mounted fine on the desktop. Took it to the laptop, again mounted fine under the old Fedora. Tried to boot from the flash and could not see it at all no matter what bios boot options I tried. Returned to the desktop and there was no problem booting from the flash drive. But no success on the laptop until... I recalled a brief message "Press F12 to ..." So brief I had to <ctrl><alt><del> several times to get the rest that said something like "select boot device". When I next rebooted and pressed F12, it gave a menu that included USB legacy boot, USB secure boot, and my hard drive. Maybe the new Dell bios at your client needs something like that to USB boot. -- Jon H.
