Thread: Grub rescue - not booting after a partition deletion

hi all,
problem happened me after deleting partition. hoping same issue.

* * * scenario (various linux logical partitons):

ubuntu 12.04 on /dev/sda12.
fedora on /dev/sda10.
kubuntu 12.04 on /dev/sda9.
swap on /dev/sda5
others on /dev/sda6..7.
extetended partion on /dev/sda4, wich "owns" /dev/sda5..12.
primry partitions on /dev/sda1..3

linux partitions have grub on partition boot sector (*not* in mbr).

in mbr there multi-boot manager program boot various installations.


* * * problem occurred:

deleted partition sda11 (fedora). after sda11 deletion, old sda12 (uduntu) becames sda11.
when grub2 boots ubuntu shows error:

no such partion
grub rescue>


* * * solution:

fom grub rescue prompt:

code:

set                                    # see "old" stored config  set prefix=(hd0,msdos11)/boot/grub     # correct partition load (msdos11 -> sda11)  set root=hd0,msdos11                   # correct partition load  insmode normal                         # load "normal"  normal                                 # start usual boot screen

from ubuntu terminal (after booted normally):

code:

sudo grub-install --force --recheck /dev/sda11          # reinstall grub on /dev/sda11 boot sector correct parameters  sudo update-grub                                        # update /boot/grub/grub.cfg
