Hi again, the journey to finish my new PC setup is proceeding.

I’d like to “migrate” my old Windows 10 SSD + storage HDD to make it accessible from the new build, which uses Debian as a primary OS.

I have tried following the first part of this wiki but when accessing the GRUB page at startup the only boot option is Debian.

I have never dual booted, but is this option feasible? How can I detect the other SSD and add its Windows 10 to the GRUB startup boot menu?

Thank you!
