Windows 7: Disk Management cannot detect any Primary Drives

Disk Management cannot detect any Primary Drives

Hi all,

My Disk Management detects my C: Drive as a Logical Drive instead of a Primary drive while EaseUS Partition Master detects it as a Primary drive.

The problem now is that because it because Disk Manage detects it as a Logical Drive, I am not able to delete Free Space to change it into unallocated space to install dual boot Windows 8. (Triple, including Windows 7 and Ubuntu)

Why are the two programs getting different results ?

By right, C Drive should never be a Logical Drive in the first place.

Is there a way to change it back to Primary so I can create Unallocated Space again ?

I had no problems with installing Ubuntu at all.... hope to solve this issue ASAP.

Thanks !

Regards,
Zeke

I'd probably use Partition Wizard bootable disk to see what it says. It's more reliable and flexible than Disk Management.

I'd guess Disk Management is wrong. It shows System Reserved as logical, system, and active. It's my understanding that Windows can't boot if system and active flags are on a logical partition. It's OK for C to be logical, but not System Reserved.

Can you do what you want to do in EaseUS?

In EaseUS, the free space is already marked as Unallocated. But the thing is when I run the Windows 8 setup, they follow what is shown on Disk Management, not on EaseUS so I can't install it...

What I would do is make Recovery Disks, then using only PW CD delete PQ Service, rightclick each of the other partitions to Modify>Set to Primary, OK. Then rightclick SysReserved, grab and slide it all the way to the left, click OK. Ditto Win7 partition, OK, Apply all steps.

If you keep PQ Service it needs to be converted to Primary to ever boot. This should reveal that SysReserved is indeed Primary, or you can convert it too, then install WIn8 and Linux distro to Logical partitions you create in Free Space.
