I have Ubuntu 12.04 loaded on a desktop AMD64. After updating with file manager I cannot boot anymore. When I insert the 12.04 disk this is what I get.
Bad Bios checksum
Starting Bios recovery
Checking for CD Rom
CD Rom found
Reading file P5RP.ROM
File P5RP"rom NOR FOUN
It keeps going into this loop and I cannot enter into the BIOS.
Without the CD in:
Checking for CD-Rom
CD_Rom not found
Checking for USB devide
USB device not found
Continually in a loop also.
I would reinstall Ubuntu 12.04 if only I could start anew from the CD, bnut I cannot enter the BIOS.
How can I get out of these loops and enter BIOS?
HELP HELP HELP PLEASE!!!!
