Hello TH Crew,

I have an external Hard drive where I backup some installation files and my personal data in case of a PC crash.

I some times help people in the re-installation of Windows using Windows disk. Sometimes I get issues of worn out CDs.

Sometimes I just copy the files from the CD into the drive and boot from the drive on the PC to be fixed!

I want to know if I can use the same drive as backup and still have a Bootable OS on it.
 
Thank you V1ctor89

Is there a way I can hide the Bootable files so it doesn't even show up when plugged in a PC so it is not tampered with? And it would still be detected incase I need to boot from it?
