Abbreviated procedure...
ps: you can't really have two sda4 partitions...
Make sure that you have a good backup of your important Ubuntu files, as this procedure can corrupt or loose data.
The use of an extended partition (sda4) makes this a little difficult. I'll outline the easiest way first, and we can add more to the procedure if we have to.
Keep these things in mind:
always start the entire procedure with issuing a swapoff
on any mounted swap partitions, and end the entire procedure with issuing a swapon
on that same swap partition
a move is done by pointing the mouse pointer at the center of a partition and dragging it left/right with the hand cursor
a resize is done by dragging the left/right side of a partition to the left/right with the directional arrow cursor
if any partition can't be moved/resized graphically, you may have to manually enter the specific required numeric data (don't do this unless I instruct you to)
you begin any move/resize by right-clicking on the partition in the lower part of the main window, and selecting the desired action from the popup menu, then finishing that action in the new move/resize window
Do the following...
Note: if the procedure doesn't work exactly as I outline, STOP immediately and DO NOT continue.
- boot the a Ubuntu Live DVD/USB
- start
gparted
- resize the left side of sda4 (extended partition) left 50gb
- move sda5 partition all the way left
- resize the right side of sda5 all the way right
If it looks correct, hit the Apply button.
