i recently purchased an HP mini 110. but then i was accidentally able to compressed the drive C which has the OS. and when i started using my product, theres this bootmgr. i was told my files are dead but it can be restore if i can uncompress the drive C. can i really restore it back? what will happen to the OEM of my product? can i just install another OS and use the product key seen below my notebook? will that still make my OS original?
