14.04 Trusty Tahar - after install, will only boot for memory check

[kdormuth2]

Hi all,
I upgraded to 14.04 this weekend, and it seemed to all go just fine - no errors, everything completed ok. When I rebooted, I got the usual error about a missing GRUB (I have a partitioned machine), so I booted from an old cd (10.10) and fixed that. Now, when I boot, it gets to the "select OS version" screen, and my only option is to run a memory test. I can't actually boot into the OS.
How can I fix this?
TIA,
Kristin

What procedure did you use to fix grub with the 10.10 disc?

[kansasnoob]

I see Boot Repair (https://help.ubuntu.com/community/Boot-Repair) is not available for 10.10:

Can you somehow burn or otherwise acquire a Trusty live DVD or USB?

If not at least post the output of:


sudo parted -l

We might be able to update grub in a chroot ................ I'm really rusty at doing that though :(

To fix the grub, I followed these steps:
cd /mnt
mkdir boot
cd boot
sudo mount /dev/sda3 /mnt/boot
sudo grub-install --root-directory=/mnt /dev/sda
sudo umount /mnt/boot

I can try to download TRusty to a USB - should I just try to install again, from there?

Not sure what you mean by "install again". If you mean reinstalling Ubuntu I'd say no, there's a good chance grub can be fixed using Boot Repair:

https://help.ubuntu.com/community/Boot-Repair

And if not at least the Boot Info link would likely tell us what we need to do to fix it.

Should you need to reinstall Ubuntu at any point please beware of this bug:

Ok, I'll download it tomorrow at work and try the boot repair tomorrow evening.

BTW the download page has instructions regarding how to create a Live USB:

http://www.ubuntu.com/download/desktop

Be sure to select the proper download. I think you need a 64-bit image to repair 64-bit installs, and a 32-bit image to repair 32-bit installs.

Just burn Boot-Repair (https://help.ubuntu.com/community/Boot-Repair) to a CD/USB: http://sourceforge.net/p/boot-repair-cd/home/Home/
This will be small download compared to downloading 14.04 again.

Hmm. I downloaded the Boot Repair tool, but when I reboot the computer with that cd in the drive, I still get the same result (memory test is the only option). It doesn't seem to be running.
Any advice?

Also, in reply to an earlier question, here's the output from "sudo parted -l":

Whew!
I was able to install the boot repair tool manually (trading out "saucy" for "maverick," since that's the version of my live cd). For some reason it had trouble with "gawk," but when I did "sudo apt-get install boot-repair --fix-missing" it was able to finish the install.

I'm finally up and running with 14.04. :-D

Thanks for your help!!

This is because you should choose CD drive as your first boot drive in BIOS.

I am glad that you have fixed your boot issue.
