I have searched here on this site and others on the web and have tried to expand sda6 after removing several other OS/partitions with GParted... no success. Please guide me to the instructions or help! I want to use the entire hard disk for this Ubuntu 15.04 installation currently on sda6. Tried to post a screen snapshot of GParted but notified I need "10 reputation" to do so... that is not helpful to solving problems for a newcomer to the site. end rant.
I am booted via Ubuntu live USB. I have deleted all previous partitions and am left with:
/dev/sda1 ext4 size 201 MiB used 140.05 MiB unused 60.95 MiB
unallocated size 174.53 GiB
/dev/sda2 extended size 123.37 GiB
/dev/sda6 ext4 size 121.37 GiB used 115.02 unused 6.34 GiB flag = boot
/dev/sda5 linux-swap size 2.0 GiB
Why is sda6 mounted? I did "swapoff" as suggested... still can not resize partition.
