Boot Error L01 0101 0101 0101

Greetings,

I tried to load Mandrake Linux 8.0 on Dell
Dimension 4400 with three hard drives. Silly me; I should have disconnected the other two
drives prior to loading on the target drive.

Now, when I try to boot to the original O/S
(WinXP home) it get the following error:
L01 0101 0101 0101 0101 0101
... it scrolls up the screen until the system is reboot.

Linux did something to boot files on the
WinXP hard drive but what ?

Is there anyway to recover the WinXP hard
drive ?
