I've been following the instructions on this page to copy my Linux partition from one partition to another on the same drive. (I'm doing this because I want to move it from /dev/sda3 to /dev/sda4 so that I can then resize /dev/sda2 and use my drive more efficiently).
I got up to "1. Reboot you machine again" under Step 6, but 'UBUNTU' on the copied partition never appears in the grub boot menu. I only ever see my original /dev/sda3 version. I have tried reinstalling GRUB and it says it's been successful, but there's no change.
Are those instructions wrong? Is there just something wierd with my computer? Can you suggest how to get this working?
