"Not a fixed MBR disk" after format

[Vader]

So I reinstalled windows 7 ultimate 64 bit yesterday, and when i tried to make my HDD active, It wont let me. I tried doing it through the disk manager and through the command prompt. I have reinstalled ~4 times in 2 days trying to activate windows and making my disk active. Any way i can get my disk active without formatting again? 

 

Edit: "Not  a fixed MBR disk" is the error message i get.

I think you may have to format.

I have formatted 3 times and kept getting the same error.

So the OS is installed on the HDD?

Yeah the OS is installed to the HDD. Ive tried making different partitions and installing in on there. Still wont work. But i can make other partitions active that dont have the OS on it

So you've never successfully installed the OS on the HDD before?

Wait so you're trying to make a mounted HDD partition active, while in the disk manager?

I am assuming you have another HDD running Windows (so you can run Windows>Disk Manager), and you're trying to activate it?

I am guessing you've tried the top 2 options in this link. Have you tried the 3rd?

use your windows 7 disk to boot into repair console, and go into command prompt and type the following

 

Fdisk /mbr

I just tried this and I get the error "fdisk is not recognized as an internal or external command, operable program, or batch file"

Sounds like windows repair isn't seeing your HDD either....

 

might be time to do a format and re-install of windows.....try it this way, make a 90gb partition for windows install on to that, then if windows boots, create a partition with the rest of the drive, don't fuck about with making the partition active, you don't need to do that.
