  • Basically: Allocate + format that remaining 411GB; move files from D, E and/or F there; remove D, E and/or F partitions; remove the 600 MB partition; extend C. There may be tools that do it for you though.

  • It is SO much vastly easier just to let Windows 11 assign the partitions.

What:

Create adjacent free space to extend into.

Why:

You can only extend partitions into directly adjacent space. If you wanted to extend the C: partition by 100GB, you need an adjacent 100GB block (unallocated or empty).

Windows prevents system partitions being moved around while the system is on, including the 600MB one that's in the way, so you may need to use additional software.

How:

There's a few different ones but for this example I'll use GParted (GPartedLive mounted to a USB) since it's the one I'm most familiar with.

Booting into GParted, you could move each partition to the right by 100GB, starting with the rightmost partition and continuing backwards (F:, then E:, then D:, then the 600MB). This will leave 100GB unallocated space adjacent to the C: partition which can then be extended into. After extending it, that 600MB system partion will be directly adjacent to the C: drive.

optional: (before you do any of this) run chkdsk then defrag each partition to reduce potential file corruption headaches.

  • What using gparted to move the partitions should be safe, it is advisable to backup all partitions to an external hard drive in case something goes wrong along the way. I would use dd within Ubuntu Live to accomplish such backups.
