Comment 68 for bug 477104

@800xlman:

I used to have that problem in Jaunty (wubi) too. Its a problem of configuration in the boot.ini file (well, that WAS in my specific case, maybe it is the same situation for you). I solved via 'test & error' or in other words, testing all the posible entrys on the boot.ini file.

In the boot.ini file look for this: 'default=multi(0)disk(0)rdisk(0)partition(3)\WINDOWS="Windows XP" /fastdetect' (this line could be slighty different in your PC) and make a copy of that values modifying the partition and the disk value: 'default=multi(0)disk(0)rdisk(0)partition(1)\...' or 'default=multi(0)disk(1)rdisk(0)partition(0)\...' or something like that (of course, only edit that parameters: disk and/or partition).

The main thing here is that you need to test which is the correct partition/disk (Windows is sooo... errr... weird (^.^') even if you set the correct parametrer, sometimes you'll get an error message of windows itself.

Try to make several entries, all different between them. You cal also check the 'root=' parameter in the menu.lst/grub.cfg file, and changing the value in the same way like in the boot.ini file.
