I've got this filesystem layout:
$ df -h | sort /dev/sda1 19G 44M 18G 1% /home/old_root /dev/sda2 440G 71M 418G 1% /home/old_backup /dev/sdb1 1.8T 1.2T 604G 66% /home /dev/sdc2 23G 7.6G 15G 35% / /dev/sdc5 887G 101G 741G 12% /home/backup
I'd like to remove all the partitions on sda, including those which are not mounted, and format the drive with a single large partition. However, grub is on that drive. How can I remove all the partitions and create one large partition without endangering grub?
I'm not against the idea of moving grub to another partition, but my BIOS makes that a pain because there is no way to ensure which drive will get which sdX designation. I'm currently running Kubuntu 14.04, this is what
