Comment 4 for bug 693671

Just tried an upgrade to Natty from Maverick using what I guess will be Alpha2. The grub.cfg generation no longer fails as script /etc/grub.d/00_header now inserts "true" into the empty load_video function. So that's good.

The upgrade doesn't clutter /boot/grub with the grub modules known to break wubi booting either. Another plus. (Although the lupin-scripts remain unchanged so the problems could occur later)

Final note: tried to do a brand new Wubi install - even though the Wubi.exe hasn't been updated since December 2010. It now fails even with the workarounds mentioned in post #1 to replace the bad wubildr. It gets into a tight loop with an error about the root filesystem has not been defined.
