Follow-up Comment #3, bug #31548 (project grub): I've performed 4 different clean installations of OS on the machine, always with the same BIOS and boot loader configuration:
boot order: CD-ROM, HDD (only hdd on system at installation time) boot flag set with installer partitioner boot loader installed to MBR of first and only hard drive. Both ubuntu 10.04 and 10.10 failed to perform the first reboot after OS setup; A test with Windows XP booted correctly; A final setup with ubuntu 8.04 booted fine, even after a dist upgrade to 10.04. Most relevant difference seems to be the MBR / boot loader: both windows and Grub1 were booted by the BIOS, Grub2 were not so I thought of a Grub2 issue. If there is another software setting the MBR besides GRUB during the setup then that other software might bring the issue as well. After each failing to boot setup I've also tried removing the CD-ROM from the boot order, with no success. Error 2 was recorded before the final 8.04 setup, again with 10.10 on a different drive temporarily connected to the system (and for that I did not verify the BIOS setup) Partitioning scheme was always the same with root partition as the first partition on the drive. Finally, regarding GPT I have not configured any partition table format so the default for each installer was used, however I've always set the bootable flag during partitioning. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?31548> _______________________________________________ Messaggio inviato con/da Savannah http://savannah.gnu.org/ _______________________________________________ Bug-grub mailing list Bug-grub@gnu.org http://lists.gnu.org/mailman/listinfo/bug-grub
