    I suspect the problem lies with the three month old Samsung drive or with the Windows boot file being corrupted or not recognized for some reason much of the time. I can literally run 25 starts that fail, and then leave the computer off for awhile and it starts up on first or second try. A strange thing is when I run "bootrec /rebuildbcd" (from Windows install media), it usually recognizes one Windows installation and gives me the option to "Add installation to boot list? Yes/No/All." When I answer Yes, the response is "the element can't be found" or something to that effect. Not sure what to make of it, except either the SSD is bad or the cloning of the old SSD wasn't successful. Thanks,
    You are mixing up different things. You are wasting your efforts repairing the BCD Store without repairing the MBR, the boot loader and/or partitions structure (see: diskpart) among other things to do prior to repair the bcd store for that matter.
    There is good guides on the net to do that. Your googlefu skills you have to practice if you absolutely want to clone your drive that was installed in Legacy (MBR) mode.

    I suggest you find a UEFI GOP vBIOS for your graphic HD7750 card and re-install Win 8.1 in UEFI mode. That way you will be able to play with your favorite features (it seems) like ultra-fastboot and secure boot.
    Regards

    Running "bootrec /rebuildbcd" is part of the MBR repair! Have also run diskpart a couple of times and it likewise failed at some point. For cloning, I use Todo Backup. As far as I can find, one person developed a UEFI/GOP bios patch for the Sapphire 7750, but that is for the low profile version. Not sure yet if it would work with the Ultimate. Sapphire Radeon HD7750 - Low Profile Edition UEFI/GOP VBIOS

    One thing catches my attention about the failed starts is that it's much more likely to occur, or occur continuously rather than just once, is on restarts or while the computer/Samsung SSD is still warm, than first thing in the morning or after sitting awhile.

    See above
    Fix also the Win file system (sfc /scannow)

    That being said:
    Samsung support/toubleshooting page indicates some solutions for your problem including setting your SSD as "Dynamic Disk" in Windows "Disk management"

    It seems to be that your Samsung 850 pro might have a firmware problem and it seems to be quite common. Contact Samsung support or browse internet. There are solutions posted here and there on the net.

    Regarding your HD7750, there is some ways to do a GOP hybrid vBIOS. I did it with my HD 6850. I went the manual way and with "HD7xxx Series UEFI Patch Tool BETA" with same result.

    Teddybehr, Thanks for your post!! I've just put a question up on the Anandtech Samsung 850 beware of the firmware thread, and done the same on overclock.net "Do you want UEFI Gop on your 7950/7970? I can add it to your bios!!" thread. If it is a Samsung firmware issue, that would take pressure off having to do a clean install real soon.

    So far no one has responded on the Anandtech firmware thread about the Samsung firmware, but I also filed a support ticket with Samsung that will probably see a response after the weekend. Nothing on the overclock graphics card firmware thread either, tho the guy that wrote the UEFI patch for the Sapphire HD7750 low profile version warned me off trying it for my (Ultimate) version of that card.

    Hopefully you will have some support from Samsung soon

    As a follow up to this thread, after experiencing lots of good startups and frustrating ones, I decided 48 hours ago to do a clean reinstall with a UEFI version of Win 8.1 Pro. Obviously, there were a lot of restarts in the process of setting up again. Ironically, in the first six or seven restarts, I got three with an MBR error. Fortunately, on restart with cntl-alt-del, the startup ran through each time. Since then, each has been clean. So, at this point I'd say cloning the former SSD was the source of the problem.
