I own a Spectre X360... when booting, sometimes it boots normally, other times, often several times in a row, I get a black screen that says "boot device not found"  Any ideas on how to fix this issue?  Thanks!

There are lots of different Spectre 360 models -- some have NVMe SSDs -- and if yours is one of those, unfortunately, those tend to run VERY hot -- and when that happens, they become unstable and fail.  There's really nothing much you can do about this as this is a known side-effect of those SSDs.
