    [SOLVED] Dual Boot/Swap Question


    Hi.

    I am dual booting Vista with Ubuntu. I have been having some difficulty with it and so my partitions are a little weird. To make a long story short, the Ubuntu partition is using two swap partitions, each on a different hard drive. I would like to delete one of these but don't know how to do it without messing things up. Here are the details:

    On hard drive sda there is an NTFS data partition, a linux partition which I plan on deleting, and a swap partition which I would also like to delete.

    On hard drive sdb there is the Vista partition, the Ubuntu partition I want to keep, the swap partition I want to keep, and an NTFS data partition.

    Currently the Ubuntu partition on sdb uses both swap partitions--the one on sda and the one on sdb. I want to delete the linux partition and swap partition of sda. How can I do this?

    Here's my fstab file:

    # /etc/fstab: static file system information.
    #
    # -- This file has been automaticly generated by ntfs-config --
    #
    # <file system> <mount point> <type> <options> <dump> <pass>

    proc /proc proc defaults 0 0
    # Entry for /dev/sdb2 :
    UUID=79d71741-460f-4144-a9b9-65be78194e61 / ext3 relatime,errors=remount-ro 0 1
    # Entry for /dev/sda6 :
    UUID=a71123a1-d4b3-4f7c-92ab-fe737dca5920 none swap sw 0 0
    # Entry for /dev/sdb5 :
    UUID=56d4c878-0b20-48b6-a89d-c9f5f2e6da9e none swap sw 0 0
    /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
    /dev/sdb4 /media/NTFS ntfs-3g defaults,locale=en_US.UTF-8 0 0
    /dev/sda1 /media/Videos ntfs-3g defaults,locale=en_US.UTF-8 0 0

    If I delete the /dev/sda6 entry from the fstab file would it then be ok to delete the sda6 partition?

    I think the easy way to do this is ...
    Code:
    sudo nano /etc/fstab
    and comment the line for unwanted swap
    Code:
    # Entry for /dev/sda6 :
    #UUID=a71123a1-d4b3-4f7c-92ab-fe737dca5920 none swap sw 0 0
    then shutdown and restart the system.
    After that you can remove/reuse the swap partition.
    Use the partition tool on the live CD to remove unwanted partitions.

    Ed: after you delete Linux partitions from sda you may find the system does not boot in which case boot from the live CD and reinstall grub using
    Code:
    sudo grub
    root (hd1,1)
    setup (hd0)
    quit

    It worked and I didn't have to reinstall grub. Thanks for the help.
