Can't select Ubuntu partition to boot into?

Kirk I’m a bit confused here are the results after
cat /etc/fstab

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>

# / was on /dev/sda2 during installation

I'm rather new to Linux and am still getting use to Terminal and reading what it tells me after executing commands.

I don't see a swap partition in your fstab. By the way, the image you posted does not work...

I'm rather new to Linux and am still getting use to Terminal and reading what it tells me after executing commands.

Please provide the output of:

sudo fdisk -l

And I will assist you in identifying your swap partition if it exists.

/dev/sda3 is your swap partition. This should activate it if it's deactivated:

sudo swapon /dev/sda3

[Nagantman]

Yes, I knew it was sda3, and I had tried that command just to get this

nagantman@nagantman-Dimension-2400:~$ sudo swapon /dev/sda3
[sudo] password for nagantman:
nagantman@nagantman-Dimension-2400:~$

No result?

Can I get the outputs of:

cat /proc/swaps

free

[Nagantman]

There you are-

nagantman@nagantman-Dimension-2400:~$ cat /proc/swaps

Your swap looks like it's working to me. It's normal for it to be empty unless it's needed.
