@illi@janNatan if you boot from BIOS (sometimes called legacy boot in setup menu) rather than UEFI, you can only select which disk to boot from, and the disk had to store boot details at the beginning of disk (MBR): both OSes could end up fighting over it. Linux operating systems are often careful to warn about this, but windows just assume they are the only operating system on a PC and overwrite it. (From memory, might need some checking 🤣)

I’ve not had issues since dual booting with UEFI.
