I have a dual boot Ubuntu 10.04 and Vista laptop.
My Ubuntu partions /dev/sda4 extended, which contains a /dev/sda5 ext4 and a /dev/sda6 ntfs partition.
Vista is on /dev/sda2 ntfs. I would like to wipe vista out, turn off dual boot (if possible) and use the space taken by vista to extend my /dev/sda6 ntfs partition in ubuntu.
What's the best way of doing this safely?
