Fromat or delete

If your refering to the hard drive that had the OS on it then a format would be quicker and easier.

yes i was referring to the hard drive with the old os on it. so i just tryed to format the drive and it say windows can not format the system partition on that drive

that where i was trying it from



im trying to fromat d drive

its still you system drive, are you sure you are booting from the right one?

Could be wrong. But i believe where your running into an issue is it's a *system* partition. So it's not allowing you to format from there trying to prevent you from messing up an os. Unplug your ssd. (as to not accidentally format it) Boot to your windows disk format the drive and be done   (prolly be a good idea to unplug your other drivers u have on there too so you make sure u get the right one.)

That OR could be that you need to be opening computer management as an administrator.

Hope it helps. But inzone was correct that's the best / easiest way to go about it.

Just noticed that his SSD isn't marked as system. Good call, probably still booting from the hdd

ive had just the ssd plug in and it boots fine how would i get my comp to put the system on the ssd befor i format the hdd

You can't format a system drive or a Windows folder , that's why I told you to go to the disk management and delete the partition , not format it , delete the partition.

sorry inzone i didn't see that post i just tried it but it comes up with the same message as before just saying i cant deleted it because of the active system partition

Run windows install,when prompted for where to install windows select the HDD and an option to format it will appear.

thanks for your input guys but i fixed it my hdd was still disk 0 when i swapped the plugs around and made the ssd disk 0 it made it the system drive and i was able to delete the old partition and make a new one
