This Page Is Going To Be about troubleshooting windows problems
so few hours ago i faced a problems which i shirked a 39 GB From The Disk But I Was Not Able To Extend The Disk Again
So what I Did is The Following
Run CMD As Admin
Run This Command : diskpart
Run This Command : list disk
then you will choose the disk number you are targeting
Run This Command : select disk <disk #> ( Usually 0 )
Run : list partition
select partition < number of the partition you wanna delete >
delete partition override
Done ! ..... I Hope this was useful
