hoho..that way cannotla my fren...copy & paste not same with Norton Ghost or Acronis, u just copy the things inside c:, not all including the registry, and some others, can't simply just copy and paste to run the OS, that's why u need CD to install OS, Norton Ghost is use if u have do some installing and setting of the OS (in previous installation), and u want it become like what u hv set after in new installation, there where the Norton@Acronis become useful....correct me if i'm wrong

oo..i see, thanks, u r rite, the registry file is inside the c:, i'm just thinking if u just copy entire c:, then paste inside new clean hdisk, then run the new hdisk, the OS can run perfectly???regarding the issue of registry or other system files??the regedit will be exactly the same from what your copy???
