How to partition a Windows disk while saving data?

Question

linux

I want to install Linux on a laptop, but I would like to try it first so that the ability to boot Windu is preserved. The trick with disk compression gives only 6 GB, this is clearly not enough. Whereas there are 57 gigs of free disk space. Is it possible somehow from under Windows or from under Linux installed on a USB flash drive - bite off a piece of hard to install Linux? Or, again, from under Linux, save the disk image to a third-party screw, so that later it could be restored, in case I decide to return to Windows?
Tell me, pliz, the corresponding free software.

Answer 4

AOMEI Partition Assistant from free.
Naturally, before such operations, it does not hurt to have a backup of the system disk on external media, the easiest way is in the form of an image, and a recovery flash drive. Especially if you are still going to experiment with dualboot. The image can again be made free by AOMEI Backupper.
