    HELP! Cant unmount partition, need to unmount to install

    I have a problem. I used a small 2 gb partition to put my ubuntu installation there so I could install ubuntu. Unfortunatly the damn installer needs to unmount that partition in order to make a few changes. help?

    Use gparted on the live cd, or gparted live.

    I dont have a livecd. It somehow uses the flash drive to boot off the partitioned space. and it wont boot from anything except that and the flash drive must be in the computer as well.

    gparted live is a small download:

    http://sourceforge.net/projects/gparted/files/

    Download the .iso and burn as a disk image, not a data disk, at no more than 4x. Then boot from it.

    You cannot do anything with mounted partitions, and in your situation need a live cd.

    The flash drive may have live session capability (hence gparted as well) ... assuming OP installed Ubuntu from the flash drive.

    @ theory5, are you re-partitioning because of the boot problem? Or are you accessing gparted to extned/enlarge Ubuntu? Or both?

    yes, and even after using gparted it wont work. For some reason, when I make a live usb flash drive, it doesnt work unless I have that usb drive as well as the same stuff on a hdd partition that can only be on my internal harddrive.
    idk what i did but now its letting me continue on. I then selected Install them side by side in the Prepare disk space menu and its at 0% for resizing the partition. I will post again if this does not work.

    nope now it says it cannot make the changes. So yea I need some help.
    Great I made it through most of the installation, but now its having trouble transfering files for some reason, it keeps crashing the installtion.

    Help us understand. What did not work? Resizing or installation?

    I read/responded to your other thread involving the bootloader. Because of that, I am assuming you have Ubuntu already installed in the internal HD and this thread is about resizing that partition.

    Re: HELP! Cant unmount partition, need to unmount to install

    I have no trouble resizing it with Gparted. BUT Ubuntu 9.04 during installation, needs to make changes to the partitions and to do that it wants to unmount any part of my harddrive that is mounted, but it cant because the only way ubuntu will boot on my laptop is by putting it on the internal harddrive in a partition. Thus the problem, sorry that I wasnt clear enough.
