People want to turn on their computer and have the OS boot and get out of the way. Adding a bootloader in between is just annoying. You either default it to autoboot X, and then find it frustrating that you need Y, or you set it to always pester you to choose, which is annoying in of itself. The UX experience really hasn’t improved ever and kinda can’t.
I’ve been dual booting since fedora 4, and whether it’s stock GRUB, or one of the flavours of the month GUI boot loaders, it’s the same lowsy experience. I can live with it, but I wouldn’t dare inflict it on a new user.
UEFI has somewhat changed it, as I now just default boot to Linux, but from Linux can run a script to set it to boot to Windows on next boot, and then reboot, but it’s still pretty gross to use.
USB boot is okay, but perhaps use a USB SSD, standard USBs can be very slow which will give a poor user experience. I also don’t think distro is that critical, as long as you stick to the mainstream ones. Make sure it’s one that you know well, as realistically, your gonna end up being called for support.










I was using X and Y to refer to Windows/Linux.
I do currently dual boot, using UEFI + grub2 (and also macos bootloader+asahi linux), and yes, it definitely is a personal disdain. The various bootloaders themselves don’t really change the experience that much its that you have to choose your OS during the boot process that cause the UX friction.
It may be the same as a user login screen, but it doesn’t take the place of one. So you press the on button -> wait a bit -> choose your OS -> wait a bit more -> choose your user -> wait a bit more. That extra step in there just really gets on your nerves, especially if you just want to turn on the PC and get on with something. If there was a way to set the boot choice before pressing the on button (like a physical toggle switch or something), that would be slightly better, but afaik, that doesn’t exist.
I’m not telling you to shut up, but I would suggest caution, it only takes one bad experience to irreparably damage your families opinion of linux, sometimes its better to let them come to you when their ready. But USB to demo the experience is definitely a good way to go about it. But when they are ready, I’d go all in on the distro of choice and spend some time with them to iron out all the issues. A little hand holding early on will save you a lot of headache later.
