The upgrade worked. I did a fresh Maverick install on the windows partition and used today's alternate image to run the upgrade. The upgrade worked successfully.
1. the /host/wubildr was not modified at all (I used diff to compare before an after). The Grub Menu showed version 1.98+20100804-5ubuntu2. 2. /boot/grub remained empty except for three files: grubenv, grub.cfg and unicode.pf 3. Despite differences in grub.cfg with maverick it booted fine. 4. Ran sudo update-grub - rebooted fine 5. Ran sudo dpkg-reconfigure grub-pc - no change to /host/wubildr or /boot/grub and rebooted fine 6. Reinstalled same version of grub-pc using synaptic - no change to /host/wubildr or /boot/grub. This time I was interrupted and windows booted in the meantime. On rebooting into Ubuntu it ended up at the grub prompt. So... in summary: grub-install does not run anymore as a postinst trigger when installing or reconfiguring grub-pc, and /host/wubildr is not updated. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/742967 Title: Natty Wubi grub prompt on install -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
