Physical Dump Problem [+rep]

He guys, Tried to turn my computer on today and i got a bright blue screen saying

\system32\config\SAM

File missing, corrupt or summit else

then it does some counting thing and then says finished, restarts itself and returns to the blue screen, cant get off it, My Windows XP home edition disc is broken so i cant do anything with that.

Any help?

Thanks (+rep) xxx

3 seconds in google

i dont have an XP disc or anything so its stuck still -,-

Pirate one then.

Isn't that the blue death screen? The best thing I can think of is maybe to Reboot when your starting screen comes up.

Can you boot into safe mode?

Got an XP disc from a mate who dl'd it, +repping all, thanks for the comments, Thanks for first post, this is helping alot :) xxxx
