I'm the archetypical hacker but I'd seldom hazard describing my abilities as 'super'... In the grand scheme of things most of us in the hacker world recognize the major pitfalls of domain & network exploits, so we stick to playing around with devices and working or studying for tech industry jobs, as I'm *kind of* doing now. Geophysics homework is much easier with anime & beer.
@dcj: I imagine there should be a config script prefix for grub that supports that configuration as long as you're decided on using 7; 10 has an adjunct bootloader that supercedes grub on my friend's thinkpad. I just use dedicated machines for 10 & Fedora 24 as I've avoided multibooting since I came from a mid-grade i5 machine (Dell) with tons of Ubuntu-related partitioning issues, granted that was several years back so I think you might either find things easier because you're on Arch or as a result of new bootloaders, either GRUB forks or some new code - I just use GRUB since it ships with my chosen distro. A somewhat distracted glance @ google suggests GRUB 2 might be in order.
