I was thinking of dual booting and relegating Windows to gaming, have you had any trouble with your setup? Especially with Windows updates messing up the boot settings or wiping partitions that they shouldn't?
Seems particularly risky now that MS is pushing out regular "major updates" like the anniversary update, which get handled like a system reinstall.
The only issue I had so far was that Mint wouldn't boot because Windows didn't actually shut down as instructed but went into default quick-boot mode, which made the Windows partition unmountable, which by default causes the Mint boot to fail. No other problems so far.
I had some issues with UEFI during install as well, but it worked out somehow.
Also, it seems that you can still feed the Windows 10 installer a Windows 7 key. I wanted Windows 7 initially, but the computer wouldn't have it.
Did you set the Windows partition to automount in `/etc/fstab` in Mint?
That would make Mint think that that mount is part of the system, and since the system isn't entirely available, the boot cannot proceed.
I suggest you add `nofail` to the mount options, and `nobootwait` on older that Ubuntu-16.04-derived Mint (doesn't run systemd) and `x-systemd.device-timeout=1` on Ubuntu-16.04+-derived Mint (should run systemd)
I haven't had any issues at all. The only minor inconvenience I have is needing to hit Esc immediately when my laptop is booting up so I can change what I want to boot into, the default being Windows. Now I'm running all this from an HP laptop that came with UEFI and not BIOS so I had to jump through a few hoops before it worked out.
