Windows 7: Trying to partition a HDD in command prompt

Trying to partition a HDD to install an OS. All was going well till I tried format the active partition - error: Parameter is incorrect

why are you doing this in a command prompt window? How are you bring up the command prompt, booting the computer to get to the command prompt.

And why not use some type of graphical UI program that you boot the computer from or the Windows install routine GUI for this.

Not really understanding why you are trying to do this from a command line interface.

Just asking, but why are you using the Command Prompt to do that?
Why not use Disk Management?

You could also use GParted from a Live Linux CD (my preferred method).

Have you used the "/?" switch to view the command help?

TWardy,

You are making a mistake.

Double-posting is very frowned upon.

You already have a thread where you have received clarification of your error.

Twardy, why have you posted another thread on the same subject?

Double-posting is not allowed and makes life difficult for those trying to help you.

Installing win 7 on formatted in old laptop

On the likelyhood you are installing Windows 7 then the DVD will allow you to do all of that prior to installing.
I have to agree that on face value there really is no need to do it from command line.

his original thread will shed light upon the matter:

Of course any further replies should be in that thread.
