i managed to fix it by booting from a live cd and using chroot to get into my normal ubuntu root and then coppied the backup of grub menu.lst to the real file

Looks like you didn't know what you were doing.
If you installed grub 2 as an upgrade of the grub that comes with ubuntu, yes you will receive an error.

You should research before you do something, as I did, and Grub 2 worked perfectly for me.
All I had to do was install it, and when it came up with this error:

press the a key to continue.

You should then come to this:

select chainload and press e.

Select root and then press e

Now re-name the string of root:

too uuid and press enter:

Select the uuid entry and press b to boot:

Now grub should boot safely without any errors, straight to this screen:

Do not blame a program for being bad when it is purely your fault. Set it up correctly for it to work, but don't blame it for not working if it has worked for tons of others.
