cannot expand main partition

[tech_splitter]

so i had windows 10 on a 650GB partition and win 8.1 in a 300GB parition and i decided to delete windows 10 and use just 8.1 and that worked fine

however when i deleted the win 10 parition it left unallocated space which i can format into an empty partition but not merge to the main boot partition, even after rebooting

can anybody suggest a way to do this?

which software are you using to manage partitions?

[Guest]

Boot into a GParted Live Environment.

Force all partition editing.

Well, to be honest I remember that disk management was good enough for the task. One thing you might want to do is to run the application as administrator: run computer management right clicking on it and selecting run as administrator, then go for the disk management tool.

 

If that doesn't work you might need something more powerful as MagnesiumPC suggested, GParted can be run from a bootable usb drive easily.
