Hi, I installed Windows 10 on an m.2 ssd. It automatically decided to set that as my main boot drive and in my bios, and windows boot options, the other drive where windows 7 was installed isn't listed as a boot option. I didn't remove the other drive before installing windows 10 unfortunately. I'm starting to notice a lot of minor things on windows 10 that i don't like and i'd like to be able to boot from my other drive with windows 7 on it, the issue is that i can't find it as a boot option at all. i've seen videos of people dual booting win 10 and win 7 but it seems they're creating new partitions and doing a fresh install. is there any way to have both in boot options and choose which drive i want to use?
