    Re: HOWTO: migrate wubi install to partition

    Thanks for the script and the help you give to the community. The very clear comments in the script were very helpful in refreshing my ancient (ca. 1982 ) shell scripting knowledge.

    I made one change to the script before running it. I changed ext4 to ext3 as ext3 is purportedly more reliable and I don't really need huge files or faster file operations. I also had an additional virtual disk defined (in WUBI) and the script copied the contents over to the “native” file system with no problem!

    The first boot picked up the new Linux installation but not the Windows XP one. After doing a “grub-update” then a reboot, XP was found and everything works properly.

    The “native” install seems to be quite a bit faster than the WUBI installation. If anyone is hesitant to make the change they should do it. It's quit painless and the results are well worth it. Plus it's a lot easier to change the size of real partitions using a gparted live CD than it is to enlarge a version 10+ WUBI installation or add a new virtual drive.

    Unfortunately, I didn't have to look up 'Edsel' .

    Thanks again
    Dave

    @dwachtel,

    You're welcome! Re. the filesystem, I haven't heard of any issues with ext4 - it has been used since 9.10 with Wubi installs. I know that the script that adds virtual disks uses ext3 (as does lvpm), but this is probably because they haven't been updated since the 8.04 release. I don't think it makes a lot of difference either way.
    I'm glad you found the script clear and were able to modify it as needed.

    i have no partition called /dev/sda5

    here is a screen shot from gparted.

    That' ok Just be careful with those commands... if you're not sure I advise you to use the script. Good luck.

    Re: HOWTO: migrate wubi install to partition

    Great guide and handy script. Very helpful. Thank you very much.

    Now...that I've done it all and have rebooted, how do I know that I'm in the "parition" linux and didn't boot back into WUBI? What's an easy way to tell? The boot process looks the same as before.

    Thanks again!

    You're very welcome

    The boot process should be different (unless you chose to not install grub). Instead of the Windows boot manager, you'll see the grub menu first.

    You can tell what you have booted in a number of ways... go to a terminal and see what root is mounted on:
    Code:
    mount
    #or 
    mount | grep ' / '
    It should say something like:
    /dev/sda5 on / type ext4 (rw,errors=remount-ro)
    You're still on Wubi if it says
    /dev/loop0 on / type ext4 (rw,errors=remount-ro,commit=0)
    You can also check the fstab:
    Code:
    cat /etc/fstab
    You're on Wubi if it says:
    /host/ubuntu/disks/root.disk / ext4 loop,errors=remount-ro 0 1
    If you skipped the grub install, you have to boot your new install by choosing Ubuntu from the Windows boot manager, and then looking near the bottom of the grub menu where it should say something like "Ubuntu xxxxx (on /dev/sda5)"
    If this is the case, don't uninstall Wubi without first installing the grub bootloader from your migrated install.

    That told me what I needed to know. I'm now on /dev/sda2

    You da man!

    umm...or da woman. In either case, thanks!!
