That is a LILO error (Linux Loader):
"L99 99 99 99 99 99 99 99 99 99 99 99 99 :: Lilo is unable to locate the second stage bootloader.
This error may occur, if the hard drive is in normal mode, but lilo has written the boot record using LBA logical block addressing mode. Switching the BIOS hard drive parameters to LBA logical block addressing allows the bootloader to start normally, but the system may not start properly, because the partitions cannot be located due to geometry differences."
In other words, your BIOS is set up incorrectly for your hard drive. Enter your BIOS (usually by pressing DEL or F2 on bootup) and do what it says above. Either that or you incorrectly partitioned your hard drive.
