I've had a problem with hdd space, as detailed here: No hdd space left
I've since tried to make more space using GParted. I've deleted partitions I thought were not being used, and expanded my Ubuntu partion. So my partitions are 1. Dell 2. OS Recovery 3. Windows 4. Ubuntu
Five and six were other things I didn't know, and there was some unallocated space. A long time ago I tried to expand Ubuntu backwards to take up Windows territory, but it couldn't be done. So today I thought I'd try the other direction. Now I get this message after restarting: error: no such partiion. grub rescue> How do I rescue grub? I have 12.04 on usb to use for gparted.
System: Dell Latitude E5520, Windows 7, Ubuntu 12.04 LTS, total drive space was 300Gb, with about 200Gb free space in Windows, but could not use for Ubuntu.
sudo grub-install /dev/sd(hard drive letter, usually a)
from the terminal, and that will reinstall GRUB onto the bootloader. – ExplodingKittens Jan 23 '14 at 08:06
