Mint4Win killed my Wubi installation :(

[PiX06]

I installed mint4win (the linux mint equivalent of wubi) from inside windows vista. After rebooting I found that the setup had indeed created a new startup option for linux mint that worked fine. However, the next time I tried booting into ubuntu, the bootloader simply started linux mint. I know that my Ubuntu installation still exists because I see both the mint and ubuntu folders in the root directory of my hard drive. How can I fix the bootloader so it starts ubuntu?? Any suggestions would be very much appreciated. Thanks people of facepunch :)

Did you install Ubuntu from Wubi too?

[PiX06]

Yeah I did. Is that bad?

[butre]

I have very little experience with Wubi, because it's just terrible shit, but probably.

[PiX06]

Surely it's still possible to boot into my ubuntu installation. I think it's just a matter of reconfiguring grub, although I'm not completely sure how to go about it.

[butre]

post your grub configuration. If you don't know where it is, tell me whether you have grub or grub2

[PiX06]

I have one in my ubuntu directory; (O:\ubuntu\disks\boot\grub\menu.lst) contents as follows:

# menu.lst - See: grub(8), info grub, update-grub(8)
#            grub-install(8), grub-floppy(8),

#            and /usr/share/doc/grub-doc/.

[butre]

Is there only one boot partition or is there two? There is likely some kind of conflict there.

[PiX06]

My partitions are set up as below:

[IMG]http://i184.photobucket.com/albums/x268/pishkie/partitions.png[/IMG]

Ubuntu is installed in O:\ubuntu and mint is installed in O:\mint.

[butre]

oh good lord what the fuck is wrong with wubi, that destroys so many standards

[PiX06]

Huh? What do you mean?

[editline]04:07PM[/editline]

I guess you mean that the way they get wubi to boot isn't very friendly towards the more traditional bootstrappers?

[PiX06]

Can anyone help or should I just nuke my wubi?
