I have Windows 7 and Ubuntu 11.10 installed on same hard drive on different partitions. Windows has about 550GB and Ubuntu only 50GB.
I had installed Ubuntu just to test for first so I chose this quite limited partition size.
I tried on Windows shrinking the partition of Windows, no problems with that.
But, if I expand the Ubuntu partition for instance with GParted, will it cause data loss? Does it just smoothly increase the size of Ubuntu partition or corrupt all the files?
