View Full Version : [ubuntu] [SOLVED] GRUB 21 Error Dual Boot

June 6th, 2008, 12:33 AM
I was dual booting Ubuntu on separate drives.SDA for WinXp,SDB for Ubuntu with an NTFS partition as backup for SDA.I booted up LiveCD for Ubuntu and deleted Ubuntu from SDB leaving only the NTFS partition.I unplugged SDB attempting to boot into WinXp from SDA and I get GRUB error 21.I am able to see my data is still intact but I am unable to boot XP.I am not leaving Ubuntu and I do plan to reinstall.How can I boot into XP ?Something just went whacko on Ubuntu so I just deleted it and want to start from a fresh install.

Boot up with the XP cd and got to recover mode. In recover mode at the promp type.


reboot and you should boot in to XP. Then reinstall ubuntu or just grub. This may help on reinstalling grub.
