Okay, what are the specs of both PCs? Usually you cannot just move a OS to a new PC without clean installing it.

 

The way it's sounding though, it sounds like PC 2 is in UEFI mode and the Windows 7 drive is configured to run in BIOS (Just my guess).

 

I would heavily recommend cleaning installing Windows 7 onto PC 2.

Okay, what are the specs of both PCs?

the first one is a  cpu Q9300 6gigs ram and a HD7870ghz edition  mobo g41MT S2P

 the second pc IS cpu G2020 2gigs ram no gpu and mobo H61 MLV3 

 

I would heavily recommend cleaning installing Windows 7 onto PC 2.

a clean install would be easy but i have so much things in the drive "programs " that i need and reinstalling all of them is a pain in ... a pain 

 

ok thanks for your help !
