Will 2 operating systems on 2 different drives interfere with each other?

manpreet Best Answer 3 years ago

I want to install Windows and Linux on 1 system. However, according to this resource, Windows will overwrite the Grub (of Linux) during updates and Linux will overwrite the boot sector (of Windows) during updates. Will installing the 2 operating systems on different HDD's/SSD's make sure that they just can live in peace instead of constantly wrecking each other's boot partition?

You are simply not going to find a "set it and forget" solution here. If you do what you suggest you are still going to have to fiddle with BIOS boot device priority and I would not be surprised if you still got the boot loader hosed every now and then when updating.

You could also unhook the hard drive you are not using but again very fiddly.

As the question you linked states there is a fairly simple way to recover grub. If you are going to be doing dual booting it is a useful skill to acquire as grub getting hosed will happen. It is only a matter of time.
