Attached is a patch to the lupin-support package which should prevent grub-install.real from being used on wubi systems where wubi was installed to a disk other than "C:" . Instead on upgrades users with such a configuration will be warned that grub failed to install.
This is not a complete fix, and users with such a config will still eventually run into problems booting *Ubuntu* due to the core.img and modules never being updated to match incompatible updates to their grub.cfg . But their mbr won't be overwritten with a broken grub install, so they won't be prevented from booting Windows. I have ideas for a complete fix but due to the seriousness of this bug (I'm seeing on average 1 person per day with an unbootable machine due to this bug in #ubuntu and #grub on irc.freenode.net alone) I think a simple patch that can more easily get an SRU and fixes the most critical aspect is important first. ** Patch added: "lupin_grub-mkimage.patch" https://bugs.launchpad.net/ubuntu/+source/lupin/+bug/610898/+attachment/1748479/+files/lupin_grub-mkimage.patch -- grub-pc upgrade renders computer unbootable when Wubi is installed to partition other than Windows https://bugs.launchpad.net/bugs/610898 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
