Laptop Suddenly couldn't recognize Boot Drive

So, I was idling on the computer when I something very strange happened. I was using chrome and just opened the friends tab on steam (although it was derpy and just showed a black screen). I pressed ctrl+shift+esc to open task manager to close steam, but nothing happened. I then pressed ctrl+alt+esc but it caused the windows start up menu to suddenly freeze and grayed-out. After holding it for about 3 seconds, my computer suddenly had a screen that basically said, "Boot device not found" and "Please install an operating system" or something like that. Strangely, I just rebooted my system and everything worked perfectly fine.

Does anyone know what might have caused this? I should note, I have an MX100 512GB SSD and its been working perfectly fine to the best of my knowledge. Crucial Storage Executive reports the drive is in good health. Is there anything I should be worried about, or is this a strange coincidence of some sort?

 

As far as worry about, well all errors could be flukes or could be a major issue you never know until it is too late. if you have important data be sure it is backed up, BTW you should be doing this anyway. It could be once of several reasons the primary drive lost it. you may never know unless it starts becoming a recurring issue that can be tracked and repeated.

Other issue is if the drive gets lost then the event causing it may never have recorded to the drive. the fact is these can be the hardest issues to track down or the easiest as in a keystroke combo shutting the drive down that you had not previously known of.

 

to me it looks like program corruption generating random error messages since boot drive not found is message you would expect during boot, not during normal operation, unless, I don't know, some virus trying to install itself into boot sequence, but that's pure speculation.
