'Cannot format or delete system partition on this disk'

[waytoosexy]

So I bought a new laptop that didn't have SSD or OS preinstalled. Before thinking too long I inserted SSD from my old laptop intro Disk1 slot and installed Windows 10 on it. The HDD that the laptop came with remained in Disk0.

When I booted Win 10 I noticed that only a 13.4 GB partition of my 1TB HDD was visible in My Computer. So I went to disk manager to figure out what's up.
I guess a screenshot could give a better explanation.

The screenshot was made after I switched the HDD with SSD in Disk0. That didn't solve the problem.
Any ideas on how to make my HDD usable? I suppose it still has FreeDOS installed on it. I'm somewhat scared of using third party disk managers, as I feel I might not be able to boot at all.

active it in cmd.

cmd -> disk part -> list disk -> select disk 1 -> active.

or you can format it using also cmd.

cmd -> diskpart -> list disk -> select disk 1 -> clean -> create partition primary -> active -> format fs=ntfs quick -> exit

You (and everyone else) should create a bootable USB stick with a PXE environment and tools, the best one still (IMO) to date is
Hiren's Boot Disc.

Follow any online guide on creating a bootable USB stick, and have at it! Tons of HDD tools alone. Not to mention a ~100 other tools. Including a miniXP/Live linux desktop environments. Good stuff

Bad advice, I almost followed it before I realized that my boot record was on the HDD. Fixed it easily by changing boot drive in EasyBCD.

I would still recommend an OS re-install you may run into NTFS permission issues and application issues, and if the original MBR bootstrapped the the new OS install..which from what I gather is what happened...their can also be system ID conflicts.

I have also seen it where the storage controller will get confused and it will keep switching the active partition flag and break EasyBCD....

Just a heads up. And the diskpart advice would work fine -if you had had your bootloader under control/working properly.
