I'm new to Linux. I've installed Ubuntu 10.10 from Windows 7. It's not in Virtual PC, it is independent. It uses a virtual drive in c:, I have chosen it to be 10 Gb.

Now I want to increase the size of this drive. How to do this? I've configured the system for PHP MySQL and installed a lot of software and fixed wireless connection problems a lot of things i don't want to loose these things and start troubling again.

I heard of backups, but I think it will take too long. Is there any other simple and fast way?

In other words, you're using Wubi, right? As far as I know, it is currently not possible to resize a Wubi installation of Ubuntu 10.04 or 10.10.

What you can do is add another virtual disk and mount it on /home or /srv, wherever you need room. There are instructions in the Wubi guide. In a nutshell: download the wubi-add-virtual-disk script, and run the following command in a terminal (the number is the size of the new virtual disk):

sudo sh wubi-add-virtual-disk /srv 20000

I recommend moving your installation to a real partition. It'll be less hassle in the long term. In your situation, the route I recommend is:

  1. Boot an Ubuntu 10.10 installation CD/USB, and perform a quick installation on a separate partition. Don't bother configuring anything.
  2. Boot your existing Wubi installation. Mount your new direct-to-partition installation. Let's call the mount point /media/new. Open a terminal and run the following commands to overwrite the new partition with your existing data from the Wubi installation, and set up the bootloader for the new partition.

    cd /media/new
    cp etc/fstab /var/tmp/fstab.new
    rm -rf *
    sudo cp -ax / .
    chroot .
    update-grub
    grub-install /dev/sda
    
  3. Open both /media/new/etc/fstab and /var/tmp/fstab.new in an editor. In each file, there is a line with a single / in the second column. Replace the line in /media/new/etc/fstab with the one from /var/tmp/fstab.new.
  4. Reboot. You should now be in the new installation. Make sure everything is ok, then you can remove the Wubi files on the Windows partition.

Keep a bootable Ubuntu CD/USB at hand, in case something goes wrong.

Whatever you do, make backups. Making backups is the only way not to lose data.
