    Re: delete partitions without reinstalling

    Hi.

    How many partitions are there and on which one is Ubuntu installed?

    Use Disk Utility in Lucid to delete the partitions GUI way. System > Administration > Disk Utility or if you prefer you can install gparted.

    In order for us to offer advice, we need to know more than you have told us.

    What is the current state of your system?

    Meaning, what operating systems are installed and how is the drive partitioned?

    Please post the output of
    Code:
    sudo fdisk -l
    Lowercase L not 1

    Thanks.

    System -> Disk Utility, then select partitions -> delete partition

    Re: delete partitions without reinstalling

    Unless Ubuntu is on the first partition (/dev/sda1), if you remove non-used partitions, you will change the partition numbers.

    Depending on how the partitions are identified in /etc/fstab, after the partition numbers are changed you might not be able to boot. If it uses "boot by-uuid", then it could be OK.

    If you post the /etc/fstab file, we can answer that question.

    Re: delete partitions without reinstalling

    up here I've attached an image of my disk utility. See it and tell me if I really have a partition!

    it appears when I boot my computer as option to start. Plus, my disk is 320gb, but I just can use + or - 130bg... therefore, there must be a partition somewhere.

    Can you take another screenshot but this time after you have clicked on the 320GB icon?
    Thanks.

    You said you have Win7, but fdisk only shows Linux?!?

    Re: delete partitions without reinstalling

    Did you install Windows first and then Ubuntu or the other way?

    In Ubuntu, go to the terminal (Applications > Accessories) and run
    Code:
    sudo update-grub
    and see if it finds Windows (it will say so if it did).

    As dabl already asked, please post the output of
    Code:
     cat /etc/fstab
