I created a recovery DVD that boots to Windows PE and automatically DiskPart the needed partitions and then installs the syspreped O/S found in a WIM image.
The recovery disk works great, everything happens without human interaction.
I want to add another feature to the recovery DVD where it scans the hard-drive and checks if an O/S is already installed before wiping and re-partitioning the hard-drive.. I will then add an optional action which I already know how to do, however I don't know how to make Windows PE scan and detect another O/S..
Is that possible?
