For decades you could only clone one Windows install to another PC if the models were IDENTICAL which a laptop and desktop would never be.
But there is some good news here. Microsoft has a tool at https://support.microsoft.com/en-us/help/15088/windows-10-create-installation-media to download a small tool to create your choice of USB or DVD Windows 10 install media if you ever need to start over. Since W10's license is digital you no longer have to locate your product keys.
I've been trying for about a week to boot up my desktop PC. It's a Windows 10 Home edition 64-bit. Fortunately, I have a laptop with the same configuration. I changed my BIOS to boot from my USB stick, and tried to copy my laptop's system using AOMEI Backupper, then plugged the USB drive into the desktop and turned it on. I got AOMEI up and it asked me to find the .adi or .afi file AOMEI created on the USB drive. There's no way to search that drive's directories in AOMEI Backupper, so I put the USB drive back into my laptop and searched the drive for a .adi or .afi file. Neither was on the drive.
I've also tried to use Microsoft's method to back up my laptop's Win 10 system and copy it to my desktop. Every third time I try to boot up the desktop, a set of help screens appears. But in them, when I say to use the USB drive to start Windows, it tries to reboot, but unsuccessfully.
Is there an application designed to restart Win 10? Most of the apps I've seen are basically designed to create a backup of a functioning Windows computer, not to boot up a dead one. Is it just not possible to repair an unbootable PC?
