View Full Version : [ubuntu] Cannot boot into windows after upgrade

May 9th, 2010, 04:03 PM
I have searched and searched but cannot find someone with the exact problem as me. I upgraded to LL today. During the installation it asked me which parts to install grub to. I should have just checked all the boxes, but i cant remember wat i pressed.

Now my grub menu look like

-ubuntu memtest
-windows 7

when i choose windows 7, it just goes straight back to the grub menu . . .

any help would be appreciated.

I've got WinXP and it was doing that to me as well. Click here (http://ubuntu-ky.ubuntuforums.org/showpost.php?p=8930595&postcount=3) for a solution from one of the forums that has worked for many folks.

That solution didn't work for me personally, I ended up having to insert my XP disc and running fixmbr and fixboot. But I would try the above solution first since the fixboot completely erases GRUB and you end up having to reinstall it (which I have yet to do).

Here's a resource page (http://sourceforge.net/apps/mediawiki/bootinfoscript/index.php?title=Boot_Problems:Boot_Sector) setup by the same person that wrote the post dizzykittystudios linked too. It contains instructions for win7 too and also more information including correct diagnosis.

Note - there is a typo for the windows 7 command. Should be bootrec (not bootrect).
Also, make sure you do the diagnosis before trying to fix.

Finally, just a clarification - the boot sector fix doesn't remove the grub bootloader. But if you do the "bootrec.exe /fixmbr" command this will remove it. In that case, this link (http://ubuntuforums.org/showthread.php?t=1014708) shows how to reinstall grub (just the bootloader part).
