upgrading HDD failed

ok, i use norton ghost 14 to upgrade my 160Gb to 320Gb one..

now my 160 Gb got 2 partition C(sys) and D(data).

i insert the 320Gb HDD inside the computer and initialize it, ok that work..

then i make partition via disk management for this new drive F and G where F i want as sys drive

then i started use copy disk option to copy D to my G, which i want to store data there..

after that i copy C to F with the option set active and MBR i enable, then i took the 160 out and boot the 320, but now i able to login to windows, but it auto logoff, why?

can guyide me a proper way to do this? thanks
