windows vista hanging up on boot up. crcdisk.sys

[zmcknight08]

Hi guys.
So I'm using a Toshiba satellite a200-28p.  It can't boot further than loading  files screen  where  it hangs on the crcdisk.sys. I have tried booting  in all the safe  modes but I just end up on the same screen. I have also  tried to run a xp recovery  disc but again  I can't get a response... anyone got any idea what to do please help!!

Is this the XP OS disk that you received with your laptop or is this a recovery disk you made yourself? You will need to change the BIOS to boot from the disk.
