Windows 10: Unable to create C Drive partition via Diskpart

I just had a nasty virus attack which wiped out my C Drive.

Hence I am wanting to keep my other partitions and just create my C Drive and repair install my Windows.

But Diskpart for some reason is not allowing me to create the C Drive.

Can someone please tell me where I am going wrong ?






Can someone tell me what the offset will be for a partition of 198 GB ?

:)

 

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that
