Can't boot 12.04 installed alongside Windows 7
- by PalaceChan
I realize there are other questions like this one here, but I have visited them and tried several things and nothing is helping. One of them had a suggestion to boot the liveCD, and sudo mount /dev/sda* /mnt and to then chroot and reinstall grub. I did this and it did not help.
Then on the Windows side, I downloaded a free version of easyBCD and chose to add a Grub2 Ubuntu 12.04 entry. On restart I saw this entry, but when I click on it it takes me to a Windows failed to boot error, as if it wasn't even trying to boot Ubuntu.
I have booted from Ubuntu liveCD once again and have a snapshot of my GParted
I ran this bootinfoscript thing from the liveCD, here are my results:
It seems grub is on sda. I just want to be able to boot into my Ubuntu on startup.

How can I get this option?
When I was using easyBCD, it kept saying I had no entries at all, so I did the add entry thing for Ubuntu many times and I see several of those on boot screen now. I'd love to get rid of all those unusable options.
