I just installed an m2 ssd in my Dell 7559 laptop. I went the route of fresh windows 10 install on the ssd. The ssd install works fine except that I have to boot via legacy mode and manually select the ssd every time. How do I make it automatically boot to the correct drive?
I figured it out myself. I had somehow set the partition to MBR rather than GPT when I initially installed windows. Formatted the SSD, set partition to GPT and now the laptop is able to boot via UEFI and go straight to the SSD. If you use MBR you have to set boot mode to legacy mode.
