You will need to download LVPM (from
http://lubi.sourceforge.net/lvpm.html ) and use GDebi to install it. You may have to install GDebi (use the Synaptic Package Manager). Then use the following as discussed at:
http://lubi.sourceforge.net/lvpm.html :
Resizing virtual disks using LVPM (not necessary if you're transferring the install to a dedicated partition)
Run LVPM, and once the menu appears, select either "resizehome" (to resize the /home virtual disk) or "resizeroot" (to resize the / virtual disk).
Input the new size, in MB, of the virtual disk.
Wait until the program finishes creating a new disks file and copying files from original home disk file; it will pop up a final instruction window instructing to backup the original home disk file and renaming the newly created disk file
Boot into windows and navigate to c:\wubi\disks, move the old virtual disk to a different folder as backup, and rename new.virtual.disk to home.virtual.disk (if you used resizehome) or system.virtual.disk (if you used resizeroot)
Reboot into ubuntu
Good luck. BTW, I understand your just wanting a "Yes" or "No" answer. Too often answers are given to use dual-booting and dedicated partitions, etc. While I have no problem doing that, there are times when I have good reason not to do it that way.
