Testcase 4: Lucid 10.04.2 on C: drive (ntfs partition /dev/sda2) ============================================= Grub version in wubildr at install 1.98-1ubuntu5 Grub version in Ubuntu at install 1.98-1ubuntu10 debconf-show grub-pc --> install-devices: <blank>
Test method: Add proposed to sources and update grub-pc through synaptic (not running other updates) Expected result: =========== 1. wubildr on /host (/dev/sda2) will be updated 2. grub modules added to /boot/grub 3. grub.cfg contains extra code (similar to normal install) Results ====== 1. wubildr on /host updated 2. grub modules added to /boot/grub 3. grub.cfg contains extra code grub is now 1.98-1ubuntu12 debconf-show grub-pc --> install devices changed to /dev/loop0 Conclusion ======== Results as expected, but there is still a distinct difference between wubi not installed to the same partition as windows. PS Grub menu (from wubildr) now shows 1.98-1ubuntu12 (as expected) NOTE: I don't plan to do any more tests at this point, unless the code changes. Although I expected the code to work more like Natty (updating wubildr no matter which partition it is installed to), on the positive side, it doesn't prompt to install grub to the MBR. And when it does update the grub.cfg to the state that caused the memory corruption on recreating the loopback device, it also updates the wubildr - to prevent the booting problem. Although the same bad wubildr will exist on the non windows partition installs, the bug shouldn't be triggered. However, installs with a bad wubildr where it is still booting (I've seen cases where the corruption only occurs following a subsequent kernel update) might still have problems. Also, it seems that the grub-install-devices is a factor in whether the wubildr is updated on non-windows partition installs, but not on windows partition installs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/610898 Title: grub-pc upgrade renders computer unbootable when Wubi is installed to partition other than Windows -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
