GRUB problem
 

i just took linux off of my dual boot computer, leaving Windows XP on it, and whenever i boot, i get a Grub command line, and cant get into windows, how can i remove grub and restore a straight boot to windows?

You'll have to use the XP install CD and boot to recovery mode. Then, you'll do something to restore the MBR. Search the message board for more info... I don't know exactly what you'll need to do.

GRUB Problem
 

In Windows XP, you can uninstall GRUB as follows:
Boot from the Windows XP CD and press the "R" key during the setup in order to start the Recovery Console. Select your Windows XP installation from the list and enter the administrator password. At the input prompt, enter the command "FIXMBR" and confirm the query with "y". The MBR will be rewritten and GRUB will be uninstalled. Press "exit" to reboot the computer.
