Windows 10: Unable To Delete Drive Partition On Windows Setup

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

Change partition as system and to drive C

As far as I'm aware Windows is mostly used as the C drive, therefore it is unable to delete itself so to speak, I'd recommend using your Windows installation disc and reinstalling the OS of your choice onto the known C drive. and whilst using the Windows disc delete/format the other drives/partitions to what you want/need.

EDIT: just read your Win7 disc is screwed... how about cloning your Win7 installtion to the current C drive? However I don't think this will be as effective in the long term due to your drive setup and also will no doubt leave the Vista files.
