I took 2 screenshoots, hope it will help.
as you see I have 4 primary partitions and 1 unallocated space.
I bought my computer about a week ago, and everything was set up here my lenovo, all partitions. So, partions SYSTEM_DRV probably contains drivers
, Windows7_OS - operating system and few other programs (it had about 700GB but I shrinkaged it to Windows7_OS and unallocated), LENOVO - drivers, aplications and the last one is rescue partition probaly, with backup.
I don't have any other data on my computer yet.
I would like to create a partition from unallocated space.
Additionally, I would like to shrinkage more my Windows partition to 100GB (it has now over 300) but disk managemet doesn't allow me to do it although I use only about 40GB from 300). But let's focus on the first problem now - creating a partition from an unallocate space.
