This question already has an answer here:

Recently, I reinstalled Ubuntu as it was just, not happy. I noticed that Ubuntu had updated from 12.04 to 13.something, I can't recall.

Once booting, I immediately noticed a change. In 12, it automatically gave me an account with my name, where I put in my password.

In 13, however, it gives me a login, where I put in my username, then my password. That's fine, I can do that.

Except, there seems to be a problem. From what I can tell, Ubuntu seems to have forgotten to make a default administrator account.

At least, that's my understanding of the situation. I logged in with guest session and went to accounts, and it seemed that the only account there was, was the guest session.

After some searching, I came across various fixes. I had planned to go into recovery and use the following commands:

Useradd username -m -s /bin/bash Passwd username Adduser username sudo

Or at least

ls /home

To check if there really was an admin account.

The issue is, holding left shift to go to the boot menu.

When I select Ubuntu from the bootloader, I have tried numerous times with different timings to hold "shift", but the issue is, instead of bringing up this lovely little screen:

I get a bare, black screen, with a underscore flashing at the top left corner. It does that for several moments and then the OS crashes, and I have to press the on button again.

If I can get to the boot menu, I think I'm golden.

I couldn't find anything else on this, so excuse me if I missed out.

All best, thanks in advance.

This question was marked as an exact duplicate of an existing question.

Er hrm 13.something probably means 13.04, which is unsupported by Ask Ubuntu since it is a development release. – smartboyhw Feb 17 '13 at 14:19

Seems like this may be an issue with grub after the installation of a new OS. I'd try booting from a live USB and install boot-repair, select the simple recommended settings, and see if things work out. More info here

Strange that it's an alpha build, I used the same installer than previously downloaded Ubuntu. Excuse the duplicate, my searching skills are apparently not as good as I thought they were. – Tadhg Feb 17 '13 at 16:06
