Ubuntu: allot more space to ubuntu on laptop dual booted with windows 10 pro


My lenovo p50 laptop has 64gb dd4ram and 1TB SSD.
I don't remember how but I allocated 500gb to ubuntu and 500gb to win10.
However, my ubuntu is complaining that it is running out of space. It shows only 75GB is available when in reality I have 500gb.

I looked at : Give more Hard disk space to Ubuntu and Add more disk space for linux from windows in a dual bootable machine ; but didn't quite follow the solutions.

Please tell me to allot all the 500gb for usage safely without breaking anything.

Update: looks like somehow something is taking up all my space :(

Windows 10Pro partition has no personal data whatsoever, is there a safe way to allot ubuntu another 250 gb without harming ubuntu or win10 in any way. I have really important stuff on my ubuntu


  1. Backup your data, and test your backup.
  2. Find what is using space, for the GUI:baobab, for the command line: ncdu and decide if you can save some space by deleting files, or going further.
  3. Boot Ubuntu from a DVD or USB, and use gparted to resize your partitions. (There is absolutely no risk of losing any data, since you've folowed step 1).
