Hello there,
I just want to buy a new gaming system, laptop, because I want to be mobile. There is only one game I cant give up that is league of legends. So I’m searching a manufactor, which can handle dual boot perfectly. I mean everytime I boot into windows and want to reboot into linux again, so my entry is gone (refind, systems and grub). Maybe there is a brand which separate two OS Hardware wise or has a BIOS espacially for such a case?
Your best bet is a secondary M2 slot, there are some laptops that allow for that. You install windows on the first, main ssd. Then you DISABLE that ssd (or you unplug it intenrally), you install linux on the second ssd, and then you enable back the first one. Then you can select using F12 during boot which ssd you want to boot from, by default it’d be windows.
I see you’re from Germany. Well, Tuxedo computers have many laptop models with two ssds in it.
