UEFI won’t boot from MBR drives unless it’s in BIOS compatibility mode. What format the drive is in isn’t determined by a firmware setting, though it can affect the boot process. I don’t think you actually understand what you are talking about here. The easiest way to install OSes both Windows and Linux is by wiping the drive, which would have solved this issue. Dual boot on single drive configurations normally have issues and will always be more complicated. It’s better to use two drives where possible in most cases. I suggest you read up on BIOS vs UEFI and how partition tables work if you want to do a complex setup like that.
Mint is known for having older kernels and therefore not supporting the latest hardware. They have a different edition for newer computers called Linux Mint Edge edition. Something Arch derived like CachyOS or another distro using recent kernels will always have the best support for bleeding edge hardware. The CachyOS installer is also pretty friendly, though maybe not as much as Mint.
Yeah it’s not always that simple. You haven’t been around long enough to see the stuff that can go wrong with installing Windows. For example I recently had Windows refuse to see both SSDs in a machine. All because of something called Intel VMD. Took me a handful of attempts before I found the problem.
When Windows installs work they are fairly simple if long, but when they don’t work oh boy.
Also they disabled that for Windows Home.
Some Lemmy users are actually just wankers. I would like it if you all stopped. It’s especially great when I have people like you who probably aren’t even experienced in tech.
