Installation "?"

[Russell Bonchu]

I a Linux Noob who just installed Ubuntu Daper Drake on a machine that 
is also running WindowsXP. The install went fine until I rebooted and 
tried to boot into XP. Now when I try it that Autocheck failed and it 
restarts and goes back to the boot manager.

Now I saw on a forum that it was possible that the XP partition was 
"hidden," and that if I went into CFDisk I could easily change it. The 
problem there is that when I started Terminal and typed in CFDisk it 
said: "Fatal Error Cannot open disk drive press any key to exit Fdisk."

Now what do I do? I need to run XP for some of my windowns only 
programs, and my wife will kill me if this doesn't get fixed in a big 
hurry. Can somebody please help? Thank you in advance!
