Re: [gentoo-user] Dual booting with Windows 10

Install it in a VM!

If your system supports IOMMU for graphics devices here is something 
special you can do:

I would instead consider purchasing an additional PCI-e graphics device 
and a PCI-e usb card then installing Windows in a VM with IOMMU-GFX, 
this way you can have your cake and eat it too.

I play my games in a windows VM on my libre coreboot workstation, it 
works great and I highly recommend it
Another reason a VM is much better is that windows doesn't get access to 
your bare metal hardware unless you forward a device so it can't send 
serial numbers back to MS for their spying/marketing database, such as 
your HDD serial number or NIC mac address, and one can avoid a bad virus 
as you can simply restore a previous VM snapshot.

controller onboard)
