I have installed Ubuntu 15.04 and it's my first time I am using Ubuntu. I installed it using 50 GB space first because I had Windows 7 installed previously and thought that i will make it duel boot but due to OEM BIOS restriction I could not do that and lost Windows 7 now. I formatted the drive on which Windows 7 was there. Now I have this space left and I want to use that 220 GB unallocated space and merge in swap and extended partitions. I have Gparted installed.
I am not aware of it how to do it. Please suggest. Step by step guidance will be very much appreciated.
