Reataurare grub
Dec

2010
Se pare ca am asteptat degeaba tutorialul despre reinstalarea grub-ului. Credeam ca imi scapa ceva dar nu…
Am facut exact ca in tutorial, si imi da urmatoarea eroare:
/usr/sbin/grub-setup: warn: Your embedding area is unusually small. core.img won’t fit in it..
/usr/sbin/grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and its use is discouraged..
/usr/sbin/grub-setup: error: if you really want blocklists, use –force.
Cum instalez grub-ul pana la urma?

Answer #2
Am incercat si cu metoda urmatoare si primesc aceeasi eroare.
This method of installation uses the chroot command to gain access to the broken system’s files. Once the chroot command is issued, the LiveCD treats the broken system’s / as its own. Commands run in a chroot environment will affect the broken systems filesystems and not those of the LiveCD.
1.
Boot to the LiveCD Desktop (Ubuntu 9.10 or later). Please note that the Live CD must be the same as the system you are fixing – either 32-bit or 64-bit (if not then the chroot will fail).
2.
Open a terminal – Applications, Accessories, Terminal.
3. Determine your normal system partition – (the switch is a lowercase „L”)
sudo fdisk -l
* If you aren’t sure, run
df -Th. Look for the correct disk size and ext3 or ext4 format.
4. Mount your normal system partition:
* Substitute the correct partition: sda1, sdb5, etc.
sudo mount /dev/sdXX /mnt # Example: sudo mount /dev/sda1 /mnt
5.
Only if you have a separate boot partition:
* sdYY is the /boot partition designation (for example sdb3)
*
sudo mount /dev/sdYY /mnt/boot
6. Mount the critical virtual filesystems:
sudo mount –bind /dev /mnt/dev
sudo mount –bind /dev/pts /mnt/dev/pts
sudo mount –bind /proc /mnt/proc
sudo mount –bind /sys /mnt/sys
7. Chroot into your normal system device:
sudo chroot /mnt
8. If there is no /boot/grub/grub.cfg or it’s not correct, create one using
update-grub
9. Reinstall GRUB 2:
*
Substitute the correct device – sda, sdb, etc. Do not specify a partition number.
grub-install /dev/sdX
10.
Verify the install (use the correct device, for example sda. Do not specify a partition): sudo grub-install –recheck /dev/sdX
11.
Exit chroot: CTRL-D on keyboard
12. Unmount virtual filesystems:
sudo umount /mnt/dev/pts
sudo umount /mnt/dev
sudo umount /mnt/proc
sudo umount /mnt/sys
* If you mounted a separate /boot partition:
sudo umount /mnt/boot
13. Unmount the LiveCD’s /usr directory:
sudo umount /mnt/usr
14. Unmount last device:
sudo umount /mnt
15. Reboot.
sudo reboot
