well, thank you again so much for your reply - I copied the named text into check-source.sh over the appropiate lines and executed sudo bash wubi-move.sh /dev/sdb4 /dev/sdb3 (for swap on /dev/sdb3 and new ext4 on /dev/sdb4) but it hangs then (graphics are blurred) and shortlybefore that, I can read something like: "Validation of source failed " ,, mmh - I do not think I can handle this at the moment ,, but thank you so much anyway

The migration script has nothing to do with graphics - it's command line only. However, it appears that there is a udevadm bug or at least a bug triggered by udevadm (possibly pulse audio) that does affect graphics. Unfortunately the udevadm is required, otherwise another bug makes Nautilus pop up browser windows whenever the script mounts partitions, which is a) irritating and b) can cause the script to fail by preventing umount operations. [long story]. In any case, a poster a few posts up mentioned that running the script in the VT console (ctrl-alt-f1) was a workaround.

But that doesn't solve your issue. This is what I suggest:
1. create a new thread - this one isn't really for support, it's for discussion of the migration wiki page
2. PM me the thread so I can find it
3. Include your script mods as well as your /etc/fstab on the root.disk (if you have it), or a list of virtual disks
4. provide the command line you use to trigger the script as well as the list of files in that directory
5. you can probably also grep /var/log/syslog to get the wubi-move.sh entries to see how things go (it's not full diagnostics but might help). And note if you are running from a live CD, you need to get this after running the script and before shutting down:

cat /var/log/syslog | grep wubi-move

I am happy to help. The core of the migration process isn't that complicated and I'm sure we can figure out what's going wrong.

FYI I've updated the Wiki page to add a link to community partitioning documentation, and also to add a Known Issue regarding the udevadm problem.

I've decided to remove the udevadm trigger (it seems to be more trouble than it's worth) and just add a message to ignore Nautilus windows that pop up. I'll also increase the Timeouts to prevent problems with umount.

I don't have a lot of time to work on the script and test anymore - my wubi machine packed up recently (hdd failure) - so I can't promise when these changes will appear in the script. But as I normally do a new release test anyway, I'll try to get this out for the release of Saucy. (Note Wubi use has dropped off significantly since it was announced that it would be dropped for 13.04; and I suspect it really will be dropped at some point, maybe even for Saucy; hence I am not too concerned about it lately).

ok - third announcement of mine: I DID IT !! with MigrateWubiManually - I simply followed the steps and I am already posting from my NEW Ubuntu - thanky you so much for interacting - things get better when you do them together ..

Cool Glad you got it sorted out!

I want to migrate from having Ubuntu 12.04 running via WUBI to having it installed on its own partitions. To do that, I have first to shrink the very partition on which root.disk and swap.disk are in order to have space to create the additional partitions I need. Those two files occupy a significant part of the used space on that partition. Is it possible to transfer those files to an external drive, so that I can shrink the partition much more than I otherwise could, and then run the migration with the two files on the external hard drive?

Yes there is an option to migrate from the root.disk (while running a live USB/DVD). Note that the live environment has to be the same architecture (32/64bit) as the Wubi install, and I recommend using the same release.

You don't need the swap.disk for this, only the root.disk (and if you have them usr.disk and home.disk have to be in the same directory as the root.disk). For the syntax see the MigrateWubi page:

To migrate from the root.disk when running from a live CD/USB:

sudo bash wubi-move.sh --root-disk=/media/win/ubuntu/disks/root.disk /dev/sda5 /dev/sda6
