I have a dual boot Windows & Linux system. I removed the Linux partition, but after that I am not able to go in to Windows XP. It is not booting. It gives me a GRUB error.
1.Enter in System Setup by pressing F2.
2.Select "File Browsrr Del Boot Option" &press Enter.
It will Show list of all partitions on hard Disk
3.Select Linux Partition You want to Delete & Hit Enter
4.Now save all Settings by pressing F10.
Now your PC will restart and Windows will start normally.
You just need to repair your MBR.
This will remove GRUB and install the Windows MBR.
I'm not sure I follow, but what do you want to do? If you want to completely remove Linux (sadly), you're on the right path. You just have to boot into your XP CD and let the Windows setup take care of repartitioning and installation. Why do you need Grub?
If you want to use both, Grub is obviously not able to find the Linux kernel that you deleted. The easiest way is to set up your partitions with something like Gparted, reinstall XP first, and THEN your Linux distro (with Grub)from an iso or network.
