My partitions are:Ubuntu's / on /dev/sda1Ubuntu's /home on /dev/sda6/Crunchbang's / on dev/sda7Now I want to install Backtrack, but for this I need to get rid of Ubuntu's /home and move its content somewhere else (whichever of the other partitions).How should I go about and do that without messing up the partitions table and the boot loader?
Move and empty /home partition of Ubuntu
ubuntu;boot;partition;dual boot;home
I think it should be safe to resize /dev/sda6 without losing any data. You can do the following:First of all, to be sure, keep a backup (the contents of /dev/sda6 fit in /dev/sda1)Shrink /dev/sda6 (right click, then resize/move - I think it is better to shrink moving the right arrow). This will leave some unallocated space.Right click on the unallocated space and create a new partition there. Move the arrows to fill the whole space.Hit applyThen you can install backtrack on the partition you created from the unallocated space. The partitions table doesn't get messed up, it gets automatically updated by gparted with no problems. As for the bootloader, if you are using GRUB you may use 'update-grub' from an Ubuntu terminal after installing backtrack so it is included in the boot menu.Very important note: While on the backtrack installation, the installer will ask you to install GRUB. Do not! I think there is a checkbox somewhere at the end of the installation that allows you to skip installing GRUB. Just reboot as the installer prompts you, boot Ubuntu and run 'update-grub'.
