I've installed different Linux distros on a variety of machines, about 30 in all, with a variety of Windows versions including 7, 8, 8.1 and several builds of 10, the latest being 10162. I've been able to have as many as four different linux distros alongside Windows 7 and 10 with no problem on the same hard drive as long as the hardware has the old BIOS system. Trying to dual boot in the UEFI environment is an absolute nightmare and varies from manufacturer to manufacturer. The only way it can be done is by disabling Fast and secure boot and enabling legacy, but some manufacturers make that almost impossible. On the other hand, UEFI and Windows 8.1 make resurrecting a corrupted Linux dual boot attempt quite easy. The Ubuntu-based distros generally work much better, (my favorites are Mint, Pearl, Chalet, Zorin, and Pinguy) but it's crucial that anyone who tries it know as much about partitioning as possible. (It's also helpful to have a copy of the boot repair disc handy.) The new Fedora file system (I gave up on Fedora 22) does not work well in a dual boot environment in my experience. I must admit, I'm very impressed with Windows 10 so far.
P.S. For simplicity and ease of use nothing beats a chromebook. That's the standard Linux needs to work toward if it ever wants to become mainstream and I like Linux but it's still only for geeks.
