Laptop Manufacturer : FUJITSU
Laptop Model: LH532 (UMA)
BIOS ver: Phoenix SecureCore Tiano 1.10

EFI installation of Ubuntu clears out the boot entries in firmware leaving user with no option but boot Ubuntu. Pressing (F2) to enter BIOS Setup has no effect as does pressing (F12) for Boot Order.
The only way to get back firmware access is to flash the bios using manufacturer provided utilities. Unfortunately Fujitsu doesn't provide a BIOS flash utility for Linux/Ubuntu. It is to be noted that installed Windows in EFI mode on the same system does not clear out firmware access but just adds the 'Windows Boot Loader' entry at the top of the boot sequence.
