Possible alternatives:
_ Connecting the USB devices in different USB ports, and performing a cold boot.
_ Connecting ps/2, wired keyboard (and mouse).
_ If the HDD is less than 2.1TB, try whether one of the DOS-based partitioning tools included in UBCD detects it and the keyboard works (with/without the DOS USB drivers).
_ Try the latest GpartedLive from gparted.org, or some other alternative.
_ Search about the specific BIOS used in this system, read its manual and instruct your friend to find the USB-related BIOS settings, so you can "play" with them.
_ If this is a UEFI system, then most of the tools in UBCD cannot work in UEFI mode. Try temporarily setting the firmware to CSM / compatibility / BIOS mode, just for the purpose of partitioning and formatting the filesystems.
