    Filesystem failure on SSD harddrive


    Hi guys,

    I have tried installing Ubuntu 12.10, and a few Ubuntu-based distros (Mint 14, Lubuntu) on my Asus Eee 1001HA.
    Booting from USB-stick and all distros run fine, installs fine and works fine after installation reboot.
    But after 2:nd reboot I get:
    Code:
    error: unknown filesystem
    grub rescue>
    Why? What's happening?
    I have used this SSD-drive before for Ubuntu distros in another computer, worked fine. Since then I have run Windows 7 on it for a little while. Shouldn't matter imo :/

    Can someone explain this to me?

    I have Boot-repair output, but wasn't allowed to post links...


    Thanks a bunch

    I checked with ls on grub rescue prompt, came up with two <msdos> partitions?
    I formatted with ext4 before install, but after 2:nd reboot the apparently get changed to FAT partitions or something...
    I have also tried reiserfs but same result...

    hello and welcome to the forums!

    ext4 partitions can't become changed to fat partitions simply from booting

    you'll need to post your output from fdisk -l so others can see your partition layout before they can offer any help

    run man fdisk for more details on using the fdisk command

    "msdos" just means, that it a traditional partition schema, in contrast to the new gpt.
    It has nothing to do with the filesystems inside the partitions.
    You must always face the curtain with a bow.

    Thanks

    Yeah I would love to do that, but Linux doesn't even boot up.

    Partitions like this:

    /dev/sda1 primary bootable Linux partition ext4, 20 GB
    /dev/sda2 extended partition
    /dev/sda5 logical Linux partition ext4, 38 GB
    /dev/sda6 logical Swap partition, 2 GB

    Hello

    When a system won't boot at all, you can generally use a liveCD/liveUSB such as Parted Magic to get the fdisk output for all connected drives. They are handy to have around for the included rescue utilities as well.

    Right now, I'm doing it all from the top.

    Lubuntu 12.10 on USB, my 60 Gb SSD disk partitioned 58 Gb ext4 and 2 Gb swap. After install I'm asked to reboot. This reboot works fine. Right now the partition table looks like this:

    Disk /dev/sda: 60.0 GB, 60022480896 bytes
    255 heads, 63 sectors/track, 7297 cylinders, total 117231408 sectors
    Units = sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes

    Disk identifier: 0x0008d616

    Nothing else done right now, another reboot done and immediately after POST get:

    error: unknown filesystem
    grub rescue>




    I will boot using Live USB.

    Lubuntu Live USB running, fdisk -l /dev/sda gives same output as just after install. Any ideas what this could be? Anything else I can try?
