    Re: Reinstalling Windows on dual boot system

    You can only run the fsck on the ext family of formats, or ext4, ext3, or ext2.
    There are other tools for other formats. And swap is unformatted so you cannot run any fsck on it (not needed).

    It did do some correction on sda3.

    Yes, I now see it. I'm wondering what effect that will have because grub seems to have stopped working and the machine boots straight into windows.

    Maybe I need to run Boot-Repair again.

    Its late so that for tomorrow.

    Thanks again for the help.

    Decided I wouldn't sleep if I didn't try Boot-Repair so tried it.

    I can boot windows but grub boots ubuntu to emergency

    sleep.............

    Had a look at the Boot-repair output and see that the fstab on sda2 is incorrect now. It relates to the old layout of the drives, eg, /media/WinData no longer exists. Ive had failed boots in the past because of incorrect fstab. I need to correct that, chroot I believe if I can remember how.

    sleep.............

    Edit: I cannot get back to this machine until end of Novermber, but I WILL be back. (No I am not sleeping!)

    Solved using notes I made years ago about fixing grub from a live usb before I left.

    Having chrooted into the old /sda2 xubuntu I # out the old entries in the /etc/fstab which were no longer valid, checked with /mount -a that it appeared ok. Rebooted, crossed fingers & legs and up came the previous xubuntu quite happy which made two of us!

    My notes below in case it helps anyone else. (If you see errors please point them out to me.)
