    Does this answer your question? How to resize partitions? – mook765 Apr 23 at 12:13
  • Do not make your NTFS too small. Windows NTFS likes 30% free to run well. At 10%, your defrag may take forever as no working room to move parts of files around. Only use Windows tools to shrink NTFS partitions & reboot immediately, so it can run chkdsk. Best to houseclean or get larger drive or have your data on another drive. You have to use Ubuntu live installer which has gparted or gparted ISO. And move partition left & expand right. Little lock icons mean you are using gparted from inside your install, so you cannot unmount it and it has to be unmounted to edit it. – oldfred Apr 23 at 13:48
