Re-install GRUB

Asked by June Nikolaisen

Can I install GRUB onto an external hd that was Windows/Ubuntu? I had to re-install Windows and lost the ability to boot my choice. My partitions and everything are still there.

My master boots to Ubuntu only. Can I copy the something from the master to the root of the external so I don't need this little hd anymore? Ubuntu calls the partition that has all the Ubuntu files on the external "12.6 GB Media". I'm pretty green so need easy-to-follow instructions.

If you want to install Grub to the MBR (Master Boot Record) of the same drive that Ubuntu is on, I would recommend doing the following in a terminal (Applications > Accessories > Terminal):

sudo grub
grub> find /boot/grub/stage1

The command above should return your main Ubuntu partition in the form of (hdX,Y) where X and Y are numbers, for example (hd0,2), but use whatever it returns as follows:

grub> root (hdX,Y)
grub> setup (hdX)
grub> quit

Let me know how that goes or if you run into problems.

If you are still having trouble with this then please post it as a new question. Only the most recent questions tend to get looked at so posting/re-posting a question just before america arrives online after work/school gives the best chance of getting a good few answers - such is the nature of the internet.

If the problem has been resolved then please follow the link to the forum thread and mark it as Solved but please give us a clue how you did manage to solve it and also use the button under where you type stuff in rather than giving me karma credit points for just sending this note to you.

Apologies, good luck and many regards from
Tom :)
