I've a system partition of 740GB which is way more than needed, I just need less than 64GB but I don't know how to unmount the system's partition since Ubuntu always needs it.

Number Start  End    Size   File system    Name                 Flags
1      1049kB 256GB  256GB  ntfs           Basic data partition msftdata
2      256GB  256GB  256MB  fat32                               boot, esp
3      256GB  260GB  4096MB linux-swap(v1) 
4      260GB  1000GB 740GB  ext4

I just want to shrink the system's partition (the ext4 one) to add another data partition, because, Ubuntu won't need a lot of space, 64GB is enougth for me.

Actually when I tried to resize with the Live Key, it crashed and the system's partition got corrupted, in fact the Live Key I used ran into issues so I needed another key, if you got the same issue, here is how I did:

  • I formatted another working key with a .iso file of Ubuntu (I had on another computer)
  • Then I re-installed Ubuntu (and resized the partitions in the same time), yay!

Really I'm really surprised and it works better than before, I'm not mad at all.
