It is not risk if Winfrid know what he did and if he want manually add chainloader/configfile to other installed system. (Boot from other installed OS) Result: - installation GRUB to "/" partition -> fault - changing boot flag -> fault It seems that grub has problem with device mapper and GPT. Reassing to Duwe it is GRUB issue. Maybe there are troubles with GPT table but I didn't modify it and partition for installing GRUB is partition number 3. In this case configuration is valid. Next error output from installing GRUB: command: setup --stage2=/boot/grub/stage2 --force-lba (hd0,2) (hd0,2) quit error output: GNU GRUB version 0.97 (640K lower / 3072K upper memory) [ Minimal BASH-like line editing is supported.

The only thing which still does not work is write a bootrecord to a partition with partition number 4 and higher, which is in the meantime supported by fedora 11. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

IMHO configuration of GRUB settings: setup --stage2=/boot/grub/stage2 --force-lba (hd0,2) (hd0,2) quit is clear and valid for using GPT. Please write more details what is wrong on configuration (hd0,2) (hd0,2). -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

If we only sync boot partitions we have a different disk layout with GPT than with MBR. So all assumptions on the enumeration just fail. My parted patch just tries to sync the first partitions. If there's no EFI driver partition, it adds a fake entry as entry 4 because otherwise Linux wouldn't load the partition table as GPT. So you definitely end up with at least partitions 0, 1 and 2 being sync'ed. If you're on a Mac (or have an EFI partition), you also get partition 3 synced. That's all we can sync to the MBR because it only allows for 4 entries. Hence I'm having a hard time understanding what exactly the issue here is. Maybe kpartx screws up the GPT detection? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Teaching it 64-bit block numbers is beyond my current resources. Alex, your code needs to be smarter about which GPs to copy! The first MBR partition entry protects the GPT, the other 3 are free to be used. Different views on partition numbers is nothing new, and deliberately accepted by the uefi consortium :-( We'll need to deal with that, later... -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
