Product: HP EliteDesk 800 G3 Base Model Tower PC
I would like to add a second drive with Win 10 on it to my Win 11 PC.
I would then have the option to boot into either on start up.
Having added it, My PC doesn't detect it as a bootable drive.
My Win 11 SSD is GUID and the Win 10 NTFS
I could do with some help please 🙂

Hi @WobblyRon
use the F9 key to access the boot menu, when powering up the laptop press the F9 key repeatedly. When you are in the boot menu, select the “boot disk” you wish to boot.
