    Exclamation Cannot boot into Win 7 after reinstalling GRUB: I get "Error 13" (details below)

    My machine has 2 separate physical disks, one for each OS. Windows (sda) and Ubuntu Linux (sdb). My Windows disk had "Vista Business x64" and the linux disk has Ubuntu 12.04. I recently upgraded Vista to "Win 7 Pro x64" and as expected, it screwed with the MBR and GRUB was not coming up at boot up time. So, I reinstall GRUB and go through the whole 9 yards (Booting from live CD and mounting the boot partition, reinstalling GRUB). Please note that I installed GRUB only on 'sdb' and I changed the boot sequence (in BIOS) to pick 'sdb' as the first disk (because o/w GRUB will not come up). I did not install GRUB on 'sda' because I was afraid, it might screw up something.

    I can see GRUB come up now on boot up with the menu options for 'Win 7' and 'Ubuntu'. Booting into Ubuntu is OK but when I choose the Windows, I get this error:

    "Error 13: Invalid or unsupported executable format. Press any key to continue.....".

    When I press a key, it takes me back to GRUB. Below are the steps that I followed from the link (http://askubuntu.com/questions/88384...alling-windows). Any clues how I can resurrect my m/c?

    Question Re: Cannot boot into Win 7 after reinstalling GRUB: I get "Error 13" (details below)

    Another interesting that I noted was as soon as I chose to boot from 'ubuntu' from GRUB, I see this message:

    "Boot from (hd0,0) ext3, <uuid>"

    I was wondering why is it booting from (hd0,0) which is the Windows disk and not from (hd0,1) which is my linux disk (check my menu.lst)???

    Re: Cannot boot into Win 7 after reinstalling GRUB: I get "Error 13" (details below)

    How did you get grub legacy into your system. Was that intentional? A few still do not like grub2, but I do.
    Grub legacy was last used on 9.04 and 9.10 was the first with grub2.

    Error 13 is from grub legacy. menu.lst is from grub legacy. Legacy did not dual boot with Windows 7 well, as I remember we had to add boot stanzas manually, but I have forgotten most of grub legacy.

    Best to convert back to grub2. This tool makes it easy to uninstall grub and reinstall grub2.

    Thanks Fred! I never realized that grub was legacy. I did OK with it with 12.04LT and Win Vistax64. I'm going to give boot-repair a shot...Can't I re-install grub2 while I'm booted onto ubuntu? The procedure looks complicated and I'm afraid I might screw up! Just wondering! Has anyone gone through this before and if you can relate your experience, that will be great!

    If you are booted into your system, you can skip the chroot and just uninstall grub & reinstall grub-pc (grub2). But make sure your Internet connection is working as it has to download from repository.

    chroot & grub uninstall & reinstall -drs305
