My BIOS has some problems and sometimes boot order of disks changes. I thought that if I insall grub on to the MBR of second data disk, it may boot. First disk(sda) is for boot and operating system, second disk(sdb) is for /var. All partitions are labeled and fsck has labels as partition references.
I have install grub on to MBR of second disk by "grub-install /dev/sdb".
I have disk which previously has been part of a /dev/md1 raid1.
Now I have moved the disk to another computer with another boot disk and want to mount it so I can copy some file. My raid partitation is on /dev/sdb1.
What shall I write? Shall I do an assembling first like
mdadm --assemble /dev/md1 /dev/sdb1
Try boot from CD, mount partition, use arch-chroot to go inside, use grub-install /dev/sda , or you can use "fdisk -l" to find your harddrive name and use "grub-install /dev/sdX" --boot-directory=/mnt/boot (X is name of disk).You can use "cat /boot/grub/grub.cfg | grep UUID" to find "old" uuid in grub.
I have a bit of an unusual problem. I've installed lubuntu 12.10 AMD64 on my system, placing / and /boot on an SSD and the rest on a hard disk. Everything except /boot is encrypted. All was well until the SSD started producing I/O errors.
I have two operating systems on my PC, 1- Fedora 12 2- Windows XP.:D
when I re-install windows xp on PC yesterday, and reboot system, doesn't display grub menu to select a OS!!:eek:
I tried to repair it with fc12 DVD 32bit, but it doesn't have any option for repairing grub (fc10 DVD had this option!!)!
therefore I tried fix it with bellow way:
