Need to change the boot order but usb keyboard is not seen , so cant access bios any ideas.

[Talons131]

have a bootmgr missing error.  I cant change boot order due to no ps/2 port and the usb says initialized but keyboard input is not recognized.  No windows 10 on but 3 crashes in a row does not start the recovery mode.   Anyone have a fix or cure i am missing.  Also tried to install windows from dvd but when it sees the disc and gives me the hit any key to boot from disk it still does not see the key board.  Using 3rd party tool it saw the disc and booted to program. then it said computer is hibernated and stops.

Do you have a spare disk-drive without any contents that you want to keep?

If so, disconnect the current disk-drive, connect this "spare", and install Windows from DVD.

If that "spare" disk-drive is completely empty, you won't see that "press any key..." prompt.

Then, connect the original disk-drive as a secondary disk-drive, and see it Windows will detect it, and see if you can read any files from the secondary disk-drive.
