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

How to extend C partition

Hi Kevin,

Thank you for the information provided.

Please to inform you that you need to have an “unallocated disk space” to the right of the Partition\Volume you wish to extend on the same drive. Only when “unallocated disk space” is available “extend” option is highlighted.

I suggest you to try these steps and check if they helps.

Step1: Press Windows + R and Diskmgmt.msc and try the following

a. Right click the basic volume want to extend.

b. Click extend volume.

c. Follow the instruction on the screen.

Step2: Open a command prompt and type diskpart.

At the DISKPART prompt, type list volume. Make note of the basic volume you want to extend.

At the DISKPART prompt, type select volume <volumenumber>. This selects the basic volume volumenumber that you want to extend into contiguous, empty space on the same disk.

At the DISKPART prompt, type extend [size=<size>]. This extends the selected volume by size megabytes (MB).

Hope this helps. If the issue remains unresolved, please get back to us and we would be happy to help.
