Happy New Year one and all,

My first task is to up-grade the hdd on my XP desktop. Currently have three internal hdd, the first one having five partitions, inc, the os, C:

I am recreating the partitions on a new 1tb hdd currently housed in a desktop caddy and all is going well in copying X gb of data across. However, obviously, the current, installed hdd has a C: partition, and the new one has the same (albeit larger) partition, set at the moment as M: I have restored an image of C: to M: but when I get around to installing it in drive bay ), I assume the computer will see it as M: and not boot from M:.

As I cannot create two C: partitions, how do I change M: to C:? Or will that happen automatically because the BIOS will recognise that M: is a boot partition and it is Disk 0?

Toodle pip and thanks
