I have got Ubuntu 12.04 alongside Windows 7 on Dell Inspiron mini 160 GB. The size of Ubuntu is not sufficient now. Can I redraw partition size when upgrading to Ubuntu 12.10, as I find myself not able to understand GParted.
Yes, You can resize the partition in the installation process. You have to select something else option in the partitioning phase. But, This can be sometimes tricky and I recommend using Gparted in the Live session.
If you are referring to resizing the partition while doing upgrade (using update-manager), you cannot. You cannot resize, delete or otherwise change the partition while using it (the partition is mounted at
If you want to upgrade with update-manager
If you want resizing of the existing partition, and also do not want to do a fresh installation, You can use the Live session. Take note that, you must have free space after the Ubuntu partition or create free space
This method might not work, if your Ubuntu is a primary partition and the partition immediately following is an extended/logical partition. (This might be possible also, but I haven't tested it).
In that case , upgrading wont help you, you need to make a fresh installation of ubuntu alongside your existing windows, and while installation, you need to specify partition.
I suggest have a look at gparted once again : http://www.dedoimedo.com/computers/gparted.html
