Windows XP not starting

[Dazza]

Hi
I have Windows XP installed in a Boot Camp partition. I can reboot into Windows XP (Boot Camp) without problems. However, when I launch Parallels (updated to build 5160), Windows XP keeps performing file checks, going around and around in circles, never getting to the Windows XP desktop scren.
This is very frustrating.
Does anyone have any ideas or suggestions?
TIA

Still no go.
Boot Camp works fine.
Parallels won't load the Windows XP desktop, it gets caught in a file checking loop.
Any takers please!
