Summarizing.
Plugin that windows 10 installation media flash dive (that I already created).
Start the laptop with cloned drive.
At startup press F12 and choose the USB flash drive to boot from.
At language selection press Shift+F10 keys, then run 'bootrec /rebuildbcd' command.
Correct?
Oops, again I replied you before you edited your message.
As I mentioned earlier, my ultimate objective is NOT moving from HDD to SSD. I have 2 Acer laptops, one with 500GB HDD, other with 256GB SSD. My objective is to move from 256GB SSD to 512GB SSD (that I bought), but keeping Alt+F10 capability. I currently jumped to 500GB HDD one to just experiment see if I can achieve the objective (I also have an extra 500GB HDD to use as a clone drive). If I succeed with it, I'll do the same steps for 256GB SSD laptop.
