    Defining Root File System

    Hello there,

    So I'm trying to install ubuntu on an old HP computer that my windows just completely crapped out on. i've been running off the live CD but want my CDROM drive back. So i've gone in and tried to install like 50 times, but every tie i get to the 4th screen i get an error message telling me that no root file system is defined, and I need to fix it in the partition menu. I've gone in the partition menu, repartitioned my hard drive, with 110GB put into an ext3 file system. I saved the other 10GB for an ntfs system, in case i want to interface with windows sometime in the future. so i did the repartitioning, checked for errors, labeled the partition, and got it remounted. But it still is not recognized in the 4th stage of the installation process. I have gone through a ton of threads on here already and have not been able to find an answer. Can anyone help?

    Once you have set a size and format (e.g. ext3) for the partition, rightclick on it (or click and select edit). Then you should get a dropdown menu with mountpoints. Choose /.

    Re: Defining Root File System

    I don't have that option, Merlin. It's already mounted to /media/butt (butt is the label - I know, real mature)

    If it helps, I saw a thread earlier between Mason Whitaker and taurus, where taurus asked him to run a command "sudo fdisk -l" from the terminal. I ran it and here's what mine said:

    Terminal Command Results:
    Disk /dev/sda: 120.0 GB, 120034123776 bytes
    255 heads, 63 sectors/track, 14593 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Disk identifier: 0x02cc02cb

    Device Boot Start End Blocks Id System
    /dev/sda2 * 1 13303 106856316 83 Linux
    /dev/sda4 * 13304 14593 10361925 7 HPFS/NTFS


    Is that even relevant?

    I don't think the spacing will display correctly, but here's what I got:

    Filesystem Size Used Avail Use% Mounted on
    tmpfs 220M 20M 218M 1% /lib/modules/2.6.27-7-generic/volati
    le

    varrun 220M 84K 220M 1% /var/run

    udev 220M 2.8M 217M 2% /dev

    tmpfs 220M 12K 220M 1% /tmp
    /dev/sda2 101G 188M 96G 1% /media/butt

    Let me know if the spacing is too unreadable and i can type it and do a screenshot or something. Thanks Merlin

    Re: Defining Root File System

    What folders and files are at /media/butt?

    It looks like some few / files have been installed, but far less than what is needed, and there is no / partition.

    Are you installing from the live cd? Have you checked the cd for errors at the opening menu? Did you do a checksum on the .iso?

    Re: Defining Root File System

    Hey Merlin,

    Baby steps here, sir. Haha. I think I'm a little lost. When i pull up butt in the browser window, all that's in there is a folder titled "Lost & Found."

    I am really starting from scratch here with ubuntu, so I don't know what files would need to be installed; I assumed the installer would do that for me.

    It seemed as though there was a / partition, at least from the output of that last command. one of the lines was rootfs, and it was mounted to "/". I think i just need to figure out how to put butt there.

    Yes, I am installing from the live CD. I do not know how to check the disc for errors; could you please help point me in the right direction for that? When i start up, it first brings up a window asking me to select a language. It highlights English by default and starts a countdown. I hti Enter but nothing happens, so I let the countdown run out and it goes into ubuntu (after taking a bit to load). I've never seen any other opening menu...

    And I don't know what a checksum or a .iso is, but if you'd be kind enough to let me know, I can try it out.

    Thanks again

    -Mike

    If it checks out, burn the .iso at more than 4x to a CD-R disk. Then boot from it, and when you get to a menu after selecting language, there is an option to check the cd integrity.

    Re: Defining Root File System

    I still have the .iso file I used on another computer. I checked it, and the hashes match. So the file I used to burn that disc is supposedly OK. But I can try it again.

    Does it have to be a CD-R or would a CD-RW work too?

    Re: Defining Root File System

    Oh, one more thing. I used ImgBurn 2.4.2.0 to burn the CD. should I try some other software?
