I have heard that Windows tends to ‘nuke’ the EFI boot partition if it’s shared with Linux. I’m not sure if it’s valid to have two EFI partitions on the same disk, but if the box can handle a second EFI boot partition, that would be a safer option.

There is also the issue that normal windows shutdown does not mean shutdown, but “hibernate”. In this state, touching any of the partitions the windows was previously using could corrupt them if mounted in Linux. (The same applies in reverse, and would be even more dangerous.) This doesn’t prevent dual-booting, but some care should be taken that the swiched-from-OS was actually shutdown.

Be in one fraction at once. H2O consist of differerent quantum-mechanical portions: para-water and ortho-water.

And it only gets weirder.

Now, provide an example that you cannot, is impossible, to translate into French.

And I’ll accept your claim of unknowing is better than knowing.

That implements a ******* VM in which all of the byte code runs in, and rest of source is just byte code listings that the linker magically gathers into a working program.
