I did a fedup from F17 to F18 on my work desktop. Now I get an infinite boot loop. Fdisk can't look at the partition table of /dev/sda because it has been coverted to GPT format (who did that?). As near as I can tell, the boot process fails after about 1 page of output near where "/" should be mounted. I can't see the error message because it reboots too quickly. Doing a rescue with an F17 bootable flash drive allows me to at least mount my /boot and / partitions, so I guess F17 understands the GPT conversion. It won't however, recognize the new system to do a boot sector repair. Should I try with an F18 bootable flash drive? Under the F17 debug prompt /dev/sda2 (boot) and /dev/sda4 (root) both give clean fsck checks. I appreciate any suggestions.
When dealing with GPT partition tables, parted is probably the tool you want use as fdisk doesn't understand them. Somebody correct me if I'm wrong, but I think a non UEFI system cannot normally boot directly from a GPT partition, so often in addition to a GPT partition table, an MS-DOS (fdisk style) partition table is created which masks out the rest of the disk as being in use to avoid non-GPT aware software from stomping over your partitions. Providing your bootloader and OS understand GPT, then the system should boot.
What does the output of "fdisk -l /dev/sda" show? I would expect it to look something like
Device Boot Start End Blocks Id System /dev/sda1 1 625142447 312571223+ ee GPT Compare that to the output of "parted /dev/sda print". Mine for example is: Disk /dev/sda: 320GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 1049kB 2097kB 1049kB bios_grub 2 2097kB 526MB 524MB ext4 ext4 boot 3 526MB 320GB 320GB lvm -- Ian Chapman. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
