Windows server unable to extend the C driver even with free space on the disk

 Issue: In my case i have 8GB of  space on my windows OS disk 0 But when i trued to extend the C driver from disk manager, the extend option is greyed out. Solution: 1.Open "Command manager" (run->cmd) 2.Type "diskpart" 3.Type "list disk" 4.Type: "select disk 0" -> if your disk is different change the # 5.Type: "List partition" 6. Note down the "Recovery partition #" having size of ~500MB 7.Type "Select partition 3" 8.Type " delete partition override" 9.Tyep "select partition 2"  ->partition # from step3, our Cdriver partition 10.Type "extend" Done
