    [Grub2] [Ubuntu 10.04] Windows doesnt boot

    I recently upgraded to 10.04, all went well.
    Except now Windows 7 does not load.
    It shows up on the grub menu, but when selected just hangs with blinking cursor?

    $ sudo fdisk -l

    Re: [Grub2] [Ubuntu 10.04] Windows doesnt boot

    You realize 10.04 is beta. I only have a 640GB drive and two 160s. I have 3 root partitions so I can boot my old version, my current version which I alternate when new versions are released and another root just for testing beta. All my data is else where so I only need 10-20GB for a root partition and with multiple drives I have different grub's in each drive.

    Because you have various drives & partitions run this script to see what is where:

    Re: [Grub2] [Ubuntu 10.04] Windows doesnt boot

    You have to be the third or fourth person I have seen with this problem. Did you request to install grub into all the partitions or is there a bug in grub that is installing it everywhere?
    You really should only have grub in the MBR not the PBR. Grub overwrote the windows boot files in the PBR.
    With win7's separaate boot partition I am not 100% sure if one or both partitions have to have grub removed but the windows repair should fix it.

    I am just copying the instructions, do not run fixMBR or else you will have to reinstall grub. You need the fixboot command, other others only if that does not work by itself.

    Vista or 7 repair
    Always run chkdsk and run again until there are no errors, that may be all that is required
    How to use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues in Windows
    http://support.microsoft.com/kb/927392
    Repair often does not work, some say run 3 times others recommend the command line bootrec.exe

    You will need to boot with your Vista/Windows 7 installation disk. Hit Enter at the language selection prompt then hit "R" to get to the repair section. You can then select the automatic boot repair tool, but it often will not do any good. Then select the command prompt (console) and type in the following commands:
    BootRec.exe /fixmbr #updates MBR master boot record do not run if you still want grub
    chkdsk /r
    BootRec.exe /FixBoot #updates PBR partition boot
    BootRec.exe /ScanOs
    BootRec.exe /RebuildBcd

    This worked a treat!

    Many thanks!

    Aside from the thanks, I just want to inform you what might caused a lot of people to have this problem. During the procedure of replacing grub legacy with grub2, There is an instruction like "If you do not know where to install grub2, just install it everywhere, it will work". I think this was in upgrade-from-grub-legacy program. This should really be changed.
