Hi All,
Inside Desktop Win7 x64, I add a new harddisk 2TB and just make 7 partitions like this:

All NTFS:
E = Active, Primary part. 150 GB
F = Logical Drive 400 GB
G = Logical Drive 400 GB
H = Logical Drive 120 GB
I = Logical Drive 400 GB
J = Logical Drive 130 GB
K = Logical Drive 263 GB

I want to change H drive as Primary, but it can't.. no menus supported!
But strangely, it supports for F and K drives only that can make partition Primary.

I'm confused, please give me suggestions on how to change the H drive into Primary?
Thanks in advance.
