So the first thing I did was remove the HDD from my laptop and replaced it with the SSD. no cloning or anything since I already moved any important documents and files to a flash drive. I also put a Windows 10 Pro ISO on the flash drive and stuck it into my laptop and restarted it. But I get errors like bootmgr is missing, and when I take the flash drive out and restart it, the error "reboot and select proper boot device, or insert boot media in selected boot device and press a key". What should I do? Thanks. I don't have the usb attachment that connects form the ssd to computer for cloning and such.
