I have experienced the same issue with my Compaq 6715b. I have XP SP3 and Ubuntu 10.10 on a single drive. When booting up the GRUB appears OK. If I boot in to Unbuntu and then restart GRUB still appears. As soon as I boot in to XP and restart GRUB is gone.
I can't say for sure what software is responsible, I decided to remove all of the HP bundled software that is shipped with the laptop that I never use. This has fixed the problem and I can now boot between operating systems quite happily without any more issues. The HP software that remains on my laptop is listed below and can therefore be ruled out as possible culprits; HP Backup and Recovery Manager Installer HP Integrated Module with Bluetooth wireless technology HP Quick Launch Buttons 6.20 F2 HP User Guide Bluetooth Addendum 0062 HP User Guides 0064 HP Wireless Assistant -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/441941 Title: grub fails after running Windows -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
