My harddisk has 4 partitions
1st - bootloader
2nd - win7
3rd - win7 ghost image from 2nd win7 (logical disk)
4th - recovery

After using easybcd to add 3rd partition win7 and boot in
I find that the system drive for this win7 is D: & using user profile in C:
and basically if i install a new win7 on 3rd partition and boot the system drive in it still display c:

so now i would like to change the system drive from d: to c:, i tried in windows management but it displays parameter errors, is there any way to do that? thanks

There is a way of changing this but it involves editing the system registry.

Editing the system registry should be done only by (very) advanced users as unrecoverable errors can be introduced in the system - the only solution later is format and reinstall.

Having two installations of Windows 7 on same computer also needs two separate licences.

If you want to have two copies of the same Windows 7 installation - one as base and one for testing it is best to have you testing copy installed (transferred) to VHD.

Post a full picture of your Disk Management and we will have a look. If it is what I think, it can be changed easily.
