Hello! I have problem with my computer for pretty long time but it wasn't annoying at start but now after a year it is becoming annoying. First I need to say that all cables are connected properly because I checked it 5 times in past few months. So my problem is that 60% of boots end up with "Reboot and select proper boot device" and 40% Windows 7 starts up normally. When error pops up i just reboot again till I get my Win7 running. Error shows up more often than getting to windows but after about 20 minutes of continous rebooting it usualy gets to windows. I changed SATA cables in all discs. Changed sata ports that discs are connected to. Cleared BIOS. Even changed motherboard's battery. I'm sure that proper disc is set to boot from it because windows sometimes boot up well.

CPU: i7 4790
Motherboard: Z87M Msi
GPU: Gigabyte Gtx 660
Ram: 24GB
PSU: Chieftec GPS-600A8, 600W
OS: Microsoft Windows 7 64-bit
 
Solution
Sounds like a "Lazy" drive, it takes some time to spin up and do it's P.O.S.T. Some older MBs had option to delay startup enough for HDDs to catch up.

It didn't happen 2 years ago with the same disc and motherboard but i will look into bios with delaying startup
