Try it this way

/dev/sda1 /               ext4    relatime,errors=remount-ro 0       1

"aufs / aufs rw 0 0
tmpfs /tmp tmpfs nosuid,nodev 0 0"

That's the contents of /etc/fstab/
i'm pretty sure my hard drive is on sda1.

That is not the content of your installed version of fstab. To view or modify your fstab, you have to mount the Ubuntu partition first. If Ubuntu is on sda1, you would:

sudo mount /dev/sda1 /mnt
gksu gedit /mnt/etc/fstab

I don't think your fstab is the problem, but that is how you would access it.

While you have the Ubuntu partition mounted, you can also try to edit the Grub menu. There are some settings in the menuentry that set the video mode, and there is a problem with at least one of them. The symptoms don't exactly match your problem, but it won't hurt to try changing them.

With the Ubuntu partition still mounted, open the Grub configuration file:

gksu gedit /mnt/boot/grub/grub.cfg

Find this line and change it to this. In Grub 1.99 it's about line 46. Do not run 'update-grub'.

set gfxmode=<some value or 'auto'>
set gfxmode=640x480

Next find your first 'menuentry' and the two lines below it:

menuentry 'Ubuntu, with Linux <kernel version>' --class ubuntu --class gnu-linux --class gnu --class os {
recordfail
set gfxpayload=$linux_gfx_mode

Change the last line to:

set gfxpayload=text

Save the file and try rebooting.

If it works we will make the changes permanent.

Try it this way

/dev/sda1 /               ext4    relatime,errors=remount-ro 0       1

So do I paste that in?

Oh. Right. This is the Ubuntu partition's fstab:

 # /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' 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>
proc            /proc           proc    nodev,noexec,nosuid 0       0
# / was on /dev/sda1 during installation
UUID=3ac9c069-613f-4065-90d0-8553f5b6049b /               ext4    errors=remount-ro 0       1

[PFactorial]

Okay, so I replaced
UUID=3ac9c069-613f-4065-90d0-8553f5b6049b / ext4 errors=remount-ro 0
with this:
/dev/sda1 / ext4 relatime,errors=remount-ro 0 1
and got this error message:

init : ureadahead main process (262) terminated with status 5

[PFactorial]

BTW it doesnt flash anymore. It just displays "Cannot display this video mode" with no "going idle"s or spazzes of yellow light

[PFactorial]

So do I change it back or do I leave fstab like that?
