Something something Microsoft evil something something arch btw
Every lemmy comment about this
The problem of which bootloader loads first depends on who updated their bootloader last. I've had different linuxes in multiboot systems steal the bootloaders from eachother.
Also BIOS mode is not good, you don't want to run hardware access through another emulation layer (CSM) that may not support features added in UEFI
For a long time, the worst thing about having Linux was what windows would do while I was dual booted. Ditching windows completely years back has made my Linux life so much more pleasant
Sure, but that's something I regret doing. Reverting back from ext4 and BTRFS drives without losing data was a pain. I did consider installing a flip switch for separate drives, but using BIOS to select the drive was simple enough after learning the lesson of deleting the wierd files that showed up on a tertiary drive from this method.
Would it be an issue if the bootloader and instructions for dual booting were from Microsoft though? It's also kinda silly to have them on the same drive anyway as it's not like it's not a known common issue.
So, what this meme is about, is that Windows upgrades typically overwrite the bootloader.
The user has installed a bootloader with the ability to select between multiple operating systems (typically GRUB) and then Microsoft comes along and undoes this change without asking.
If the bootloader and instructions for dualbooting were from Microsoft, that would imply that they wouldn't keep overwriting GRUB, or at least that the bootloader they overwrite it with, still allows you to select your other operating system.
Microsoft has no interest in fixing this, because they're the monopolist. Continuously interfering with the use of alternative operating systems allows them to keep their competition small.
