Fixing grub

[Victor_Lai]

Hi guys,

I am reinstalling a Home Server that I've installed Ubuntu 12.04 LTS server edition on.
Reinstalling from a USB key (since the server didnt have any CD roms), and I keep getting stuck on installing grub-pc into /target.

I then started attempting the grub recover from http://opensource-sidh.blogspot.ca/2011/06/recover-grub-live-ubuntu-cd-pendrive.html.

Followed every step and was OK until I attempted:


update-grub2update-grub
update-grub




The chroot prompt complains that

THe program 'update-grub2' is currently not installed. You can install it by typing: apt-get install grub2-common

When I try to install grub2-common, I get the usual Do you want to continue [Y/n]?

As I enter y, I get


Media change: please insert the disc labeled 'Ubuntu=Server 12.04.3 LTS _Precise Pangpolin_ - Release i386 (20130820.2)' in the drive '/media/cdrom/' and press enter

When I press enter, the same message keeps coming.

I exited the apt-get by Ctrl-C. When I check the /media/cdrom/ folder, there is nothing in there. I tried to mount /dev/sdb1 (where my USB is) and shell tells me that according to mtab, its already mounted there....

I am completely lost :confused::confused::confused:

Help is much appreciated....

It looks like your chroot also wanted to install the full desktop, did you want that?

From a live installer run this, or download it as a new repairCD.

Post the link to the BootInfo report that this creates. Is part of Boot-Repair:

Hello,

Finally got around to making this report.... I am going to try the repair tonight.

The report that was generated

Much thanks for anyone that could help and thanks to oldfred already!

Grub did not install. What was the error on grub-pc? It looks like it is missing entirely as you have no grub in MBR nor grub.cfg nor core.img.

From boot-Repair you can do a purge (in your case nothing to purge) and total reinstall. I would suggest that.

Do you have pc on working Internet? Boot-Repair or install of grub-pc really needs that. You may be able to change source to DVD or flash installer, but better to use Internet.

Thanks oldfred.

I ran boot-repair and it fixed grub and I was able to install the server again!
Much thanks again!
