I recently used clonezilla to migrate my os to a bigger drive. However, my new drives total size is the same as the one i replaced. Using mini partition wizard i can see the unallocated space but i cant allocate it. doesnt even 'show up' until i select the option to change drive to MBR. is there another tool i can use to allocate this space? or do i need to do a complete clean install? i hope not as i used an oem key and cant remember where i wrote it down!!
