sorry for maybe stupid and newbie question but how can i install win10 using vhdx files? The thing is that some time ago i backuped my perfect working win10 (created WindowsImageBackup folder), it contained some xml and vhdx files, after that i tried to install other system on the same laptop and the installation process failed and master boot record was overwritten. From that time i cannot access any system and theres only a message - 'no bootable device was detected' (but i can access xml and vhdx files from live boot). How can i rollback this change? If somebody could write me like for a newbie what should i do, i will be very grateful.
