Comment 29 for bug 610898

Jordan,
It's great you have a patch, but Wubi has an even bigger problem right now. The same grub update that is causing a spike in the overwritten bootloader problem (bug 581760) is also breaking Wubi installs that are on the same partition as windows (c:)
I am seeing a large number of these on ubuntuforums.org and answers.launchpad.net/wubi.
Although this fortunately still allows users to boot Windows, I do not know of a fix to the problem other than the workaround to loop mount and edit grub.cfg by hand.
It appears that this patch was not tested before releasing it, because a fresh install of Ubuntu 10.04.1 on 'drive C:' with the update applied does not boot.

This problem is almost identical in nature to the symptoms of bug 653134 (it appears to me that it's due to the same code patch but it was released on Maverick first) to which their has been no futher investigation by developers since the release of Maverick. If it is the same code patch that was known to break wubi installs on upgrade to Maverick, it is highly irresponsible that this was then released on 10.04.1 without addressing the problem.

All in all, I am dismayed by the poor development support Wubi receives and question whether Canonical should be making it available when these grub updates break it so easily.
