Windows 7 doesn't boot after Ubuntu install

Solution 1:

From your BootInfo Script, I can see that GRUB2 resides erroneously on /sda1, your Windows boot partition. I'm not much into Windows anymore, but from what I know there are tools on the Windows CD that allow restoration of bootsectors. You need to boot from the Windows CD and start the repair mode. On the command line, you can try

bootrec.exe /fixboot

to restore your Windows partition boot sector.

Then, however, you won't be able to boot Ubuntu, because there will be no more GRUB2. GRUB2 should have been installed in the MBR of /sda which is not so in your case. This means you will either have to reinstall GRUB (using a Ubuntu live CD) there, or you may find it less time consuming to reinstall Ubuntu as a whole. The latter should not be a great thing if you only installed it recently for testing. In any case, take note that you should not install Grub2 on your Windows boot sector again.

Solution 2:

In order to have windows 7 back just run the windows 7 CD in repair mode.

follow this in order to have the console : http://pcsupport.about.com/od/toolsofthetrade/ss/windows-7-startup-repair.htm

Under the console you'll type :

fixboot

and

fixmbr

Those two commands will restore normaly the whole windows 7 boot process. if not follow the procedure of the link I gave you.

So now you are in single boot with windows 7 and Ubuntu is "disabled"

In order to restore Ubuntu and activate the dual boot correctly you may want ubuntu back.

For that follow this link at the easybcd part : http://www.linuxbsdos.com/2011/05/22/how-to-dual-boot-windows-7-and-ubuntu-11-04/2/
