I switched from Windows to Ubuntu 4 months ago and I am really happy with it. I set up a dual-boot system (since I wasn´t sure how it will end up with me and Ubuntu).
After merging from Citavi to Zotero I need windows only for my scanner. The problem I have now is, that the windows partition is so big with lots of unused space and the Ubuntu partition are quite small - I should have though about this problem 4 months ago...
My partitions look like this:
Where sda3 is the windows partition, sda5 is Ubuntu and sda7 is a data partition. I want to shrink sda3 and free some space for sda5 and sda7.
How can this be done safely (and easily)?
