Hello,
I have a HP ProDesk 400 G4 mini, and need to install Windows 11 25H2 from USB, but cannot get the ProDesk to boot from USB, have selected the USB in the boot options and disabled secure boot, but no good.
Can someone tell me how I fixed this issue ?
Thanks

You're very welcome.
I'm assuming that you must bought the PC pre-owned because someone must have disabled that BIOS setting because that is not the default setting.

Hi:
In order to boot from the USB flash drive, have the flash drive plugged into a USB port.
Turn on or restart the PC.
Immediately tap...tap...tap the ESC key to get the menu of options.
Select the F9 boot options menu and from that, select the USB flash drive and press the Enter key.
The PC should then boot from the USB W11 installation flash drive.
