My laptop currently has:
sda1
sda2
- Windows 7sda5
- Linux Mintsda6
- Linux Swapsda3
- A data partition
I'm looking to erase the Mint installation and put Ubuntu down in its place without disrupting my Windows or data partitions.
I'm assuming that the way forward is to choose the 'Something else' installation type, but I'm taking myself round in circles trying to work out the device for the boot loader installation as it's unclear where to define the root file system.
I suspect the answer may be quite obvious but I'm being a bit dense.
