View Full Version : [SOLVED] No Dual Boot Option Given

March 26th, 2010, 07:37 AM
So I was using Ubuntu on my desktop. I had a windows install that I did first and then shrunk the disc and installed ubuntu. Everything was good until windows went windows on me and had to be reformatted. So I reinstalled windows on the partition and now when my computer boots it does not give me the option to chose the ubuntu partition, it just loads windows. Is there a way this can be fixed or do I need to start from scratch and reload windows and then ubuntu?

You need to tell us what version Ubuntu you have installed to get the grub menu back for example do you have 9.10 installed or 9.04 etc.

If it is 9.10 it has grub2 so do this


If it is the older grub do this.
