I have only C drive in my laptop. can i partition my c drive without losing my operating system (windows 7) and data?
Following jsc's reply, but for free alternatives, check:
Clonezilla for backups (which, as jsc said, is a good idea to do before
messing with partitions)
http://clonezilla.org/
Gparted for resizing/creating partitions
http://gparted.sourceforge.net/
I have used both products without any problems but I had to do a
small amount of reading on their webpages before (nothing too
hard though).
Both programs have to either be burned on a live CD (a cd that will
run on boot time, just like a windows installation cd) or installed on
a usb stick.
