Dear Brian, For these matters, the debian-user mailing list is the right place to go. Indeed, the Community Team is a team which is here to handle interactions between members of the Debian Community that go wrong, and tries to have the Debian Code of Conduct followed by the members of the community in their interactions. For convenience, I cc-ed the list here. As for your specific matter, Windows 10 being an UEFI system, Debian installation has to accomodate for this, and if you used the basic installer, it did indeed attempt to install grub and create the specific entry. Probably something went south there. If you indeed tried to boot "Debian", and it failed, I'd guess it's because, while the grub binary is on the uefi part of your main disk along with the windows bootloader and other potential stuff, the grub configuration is on your external drive which is not yet seen properly when you hit the "debian" entry choice (which is the one you should use, as grub will also allow you to boot windows 10), but it's a wild guess. I'll let some users to chime in, as I admit I'm not the best to help people debug such issues over mail. :/ But I'll keep an eye. Bests, -- Pierre-Elliott Bécue GPG: 9AE0 4D98 6400 E3B6 7528 F493 0D44 2664 1949 74E2 It's far easier to fight for one's principles than to live up to them.
