Grub Rescue mode - Ubuntu


Grub rescue mode prompt appears usually when you mess up with Linux or act out some weird stunt you wish you didn't. Well if you've already done it you can't change the time. Oh! By the way this could also happen if you've deleted the recovery partition and try to access it on the grub prompt. Which was my case.


Well, like anyone else I googled googled and googled. Many suggests to find an Ubuntu live CD and run it, by that we can reinstall Grub. But you may experience with some weird error, (actually a bug) which causes the PC not to detect CD-ROM. Besides it's too complex.

So if you are the victim of the above scenario, well you've come to the right place.
Then the easiest thing to do is,

1. Find a Windows (7 or Vista) Recovery Disk.
2. Boot from CD
3. Then you'll be presented with an option window.


4. Choose the Startup Repair. Follow the instructions and see if the system has any errors. If there are fix them.
5. Reboot (see if that worked)
6. If not, Choose Command Prompt, Then type following 3 commands.
bootrec /fixmbr
bootrec /fixboot  
bootrec /rebuildbcd
7. Then run Startup repair again. (Just to be on the safe side)

Now the grub should be reinstalled. Problem solved.
