Repartition my Disk

[sotnik]

Hello
I have the following partitions:
https://drive.google.com/file/d/1Og7fkKjrSsEUhhwnstRDlXvwqTpjxhmE/view?usp=sharing
I would like to remove all the windows partitions and I will run windows for some applications from VM.
Also I would like to increase  root and home partitions
What is the best way to proceed, if there is any, without destroying my siduction installation?
Thank you in advance

Well, first a complete backup of the disk/partitions. Maybe with clonezilla.
Then you could do some planning about what you want to change and what you need to keep (i.e. EFI-partition and what (and where) is needed for the BIOS) and then reconfigure/resize your partitions carefully (best via a Live-DVD/-Stick) with gparted.
