I don’t remember if Windows updates would cause it but installing Windows second definitely would. Likewise, I think upgrading (from say Windows 7 to 10) might. Basically Windows is just like “this MBR? It’s actually mine, thanks.” With no option to not erase it.
EFI systems don’t use the MBR. Windows will default to using the whole disk if you don’t use the “advanced” button, but so will most linux distro installers.
It tends to happen if you are not using the windows bootloader (GRUB for example) but if you use the windows bootloader it should be fine
Oh it just changes the bootloader? That’s not a big deal. Easy to fix from any live usb.
Also, for any distro hoppers out there… Do yourself a favour and put Ventoy on a USB. You can thank me later
With EFI systems this doesn’t matter. It was an issue with the legacy BIOS bootloader systems about a decade ago though.

I’m talking about BIOS, yeah, sorry if it was unclear. My 2009 CPU is still hanging on. Barely.
Pretty sure it happened to me on UEFI as well
