I made screenshots of Gparted
Image 1 Can I get that unused space in to the root partition? Can I delete the EFI system partition to get the space? https://i.stack.imgur.com/qPBXY.jpg
Image 2 Can I delete the EFI system partition Can I delete the Microsoft Reserved partition https://i.stack.imgur.com/yt8lg.jpg
I would like to delete unnecessary partitions and get the space too the root.
This part is solved. I linked my folders in Home and moved the data to Partition 3 as suggested in the comments. The Snap folder didn't work to link and this will become big with all new apps like Gimp etc. It seems difficult to move the snap folder.
I wanted to make a clean Ubuntu install, without any windows partition. But when I started to use it I discovered that the windows partition was there with over 900GB. I deleted it and it gave me that amount of unused space.
There it says that there are 2 disks INTEL SSD 14GB with 2 partitions P1 EFI system 537 MB P2 Linux filesystem Mounted at Filesystem Root 14 GB 81% full. I have not added anything yet because of all the problems. and 1.0 TB Hard drive TOSHIBA where all this unused space is in p3 Partition 1 /dev/sda1 EFI System 105 MB Partition 2 Microsoft Reserved Partition 3 with is the biggest Really I don't want any partition
Or is it better in my case to make a new Ubuntu installation and try to wipe out all the old partitions? I wish I could, if not it is no more space in the root for more partitions.
