in a new hp dm4 laptop, i tried to created some partitions as it had only one drive of 500GB. but there were some other primary partitions like 'recovery','hp tools'... etc so the partition manager software didn't allow any new creation. then i created a virtual disk (VHD) file of 400GB and created some partitions in it. but it doesn't feel safe to keep all the data is C drive. so i decided to remove those 'recovery', 'hp tools' partitions and create some logical drives on the disk. So, is there any way or software that i can convert that VHD fiile into physical drives? or do i have to backup all my data and then delete the VHD file.
