    Filesystem problems...?

    Hi I can no longer get into ubuntu - when I try to, I get

    No filesystem could mount root tried ext3, ext2, ext4,
    Unable to mount root fs on unknown block (8,1)

    I'm still pretty new to linux so i wont understand much techy stuff sorry - any idea what the solution is?

    Thanks guys,
    Owen.

    Re: Filesystem problems...?

    Let's get a better look at your setup & boot process. Boot the Ubuntu Live CD/USB. Choose "try ubuntu without any changes", when the desktop loads come back here and use the link in my signature to download the Boot Info Script to the desktop. Once on desktop open a terminal (Applications > Accessories > Terminal) and run this command
    Code:
    sudo bash ~/Desktop/boot_info_script*.sh
    This will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.

    Re: Filesystem problems...?

    You use wubi, I am not very knowledgeable about wubi installations. I did notice something amiss from your wubi grub.cfg file . I am not sure because you installed via wubi but in a full install the #'s in red should be the UUID of the Ubuntu partition. see here:

    Code:
    menuentry "Ubuntu, Linux 2.6.31-17-generic" {
    insmod ntfs
    set root=(hd0,1)
    search --no-floppy --fs-uuid --set 32284242284204f7
    loopback loop0 /ubuntu/disks/root.disk
    set root=(loop0)
    linux /boot/vmlinuz-2.6.31-17-generic root=/dev/sda1 loop=/ubuntu/disks/root.disk ro quiet splash
    initrd /boot/initrd.img-2.6.31-17-generic
    }
    menuentry "Ubuntu, Linux 2.6.31-17-generic (recovery mode)" {
    insmod ntfs
    set root=(hd0,1)
    search --no-floppy --fs-uuid --set 32284242284204f7
    loopback loop0 /ubuntu/disks/root.disk
    set root=(loop0)
    linux /boot/vmlinuz-2.6.31-17-generic root=/dev/sda1 loop=/ubuntu/disks/root.disk ro single
    initrd /boot/initrd.img-2.6.31-17-generic
    }
    menuentry "Ubuntu, Linux 2.6.31-16-generic" {
    insmod ntfs
    set root=(hd0,1)
    search --no-floppy --fs-uuid --set 32284242284204f7
    loopback loop0 /ubuntu/disks/root.disk
    set root=(loop0)
    linux /boot/vmlinuz-2.6.31-16-generic root=/dev/sda1 loop=/ubuntu/disks/root.disk ro quiet splash
    initrd /boot/initrd.img-2.6.31-16-generic
    }
    menuentry "Ubuntu, Linux 2.6.31-16-generic (recovery mode)" {
    insmod ntfs
    set root=(hd0,1)
    search --no-floppy --fs-uuid --set 32284242284204f7
    loopback loop0 /ubuntu/disks/root.disk
    set root=(loop0)
    linux /boot/vmlinuz-2.6.31-16-generic root=/dev/sda1 loop=/ubuntu/disks/root.disk ro single
    initrd /boot/initrd.img-2.6.31-16-generic
    }
    menuentry "Ubuntu, Linux 2.6.31-14-generic" {
    insmod ntfs
    set root=(hd0,1)
    search --no-floppy --fs-uuid --set 32284242284204f7
    loopback loop0 /ubuntu/disks/root.disk
    set root=(loop0)
    linux /boot/vmlinuz-2.6.31-14-generic root=/dev/sda1 loop=/ubuntu/disks/root.disk ro quiet splash
    initrd /boot/initrd.img-2.6.31-14-generic
    }
    menuentry "Ubuntu, Linux 2.6.31-14-generic (recovery mode)" {
    insmod ntfs
    set root=(hd0,1)
    search --no-floppy --fs-uuid --set 32284242284204f7
    loopback loop0 /ubuntu/disks/root.disk
    set root=(loop0)
    linux /boot/vmlinuz-2.6.31-14-generic root=/dev/sda1 loop=/ubuntu/disks/root.disk ro single
    initrd /boot/initrd.img-2.6.31-14-generic
    }
    Now compare the numbers in red to your ubuntu UUID from the script output:


    Code:
    blkid -c /dev/null: __________________________________________________ __________
    
    sda1: UUID="32284242284204F7" TYPE="ntfs"
    sda1/Wubi: UUID="4e83e3a3-4a90-4415-a546-50c8f9b7faa4" TYPE="ext4"
    Unfortunately I do not know enough about wubi to tell you how to make that change. But if wubi grub.cfg works like the full install of Ubuntu that is your problem.

    Wubi has some quirks and problems especially in 9.10. It is more difficult getting help for wubi as the majority of ubuntu users do not use it.

    Re: Filesystem problems...?

    I'd second that the Karmic via Wubi is not very stable. Every kernel update leaves me with an unbootable machine, and I can only boot with the 14-generic kernel.
    I believe these problems are mostly due to issues with Grub2 and Wubi playing nicely together.
