Windows 10: "No boot device found" message on boot, but SSD can be booted from through the boot menu

Hi,


I'm assisting with trying to resolve a problem on a computer running Windows 10. The problem appeared on first boot after the graphics card was upgraded.


After showing POST on the first boot it started showing the Windows 7 startup logo, before soon after reporting an that needed to be fixed. chkdsk started running, and once done the computer loaded into Windows 7.

The computer was apparently upgraded with a SSD drive at one point. Windows 10 was installed on this SSD, and the old HHD with Windows 7 installed was kept in the computer without being formatted.


Seeing that it booted to the wrong OS, the computer was rebooted. The same thing happening again. The computer was rebooted once more to enter BIOS to check boot order. There all turned out to be fine, with the SSD marked with Windows Boot Manager having the highest priority. All other options looked fine too.

To try to force the computer to boot from the SSD, the HDD was disconnected. After POST the following, well known message appeared:

"Reboot and select proper boot device or insert boot media

or Insert Boot Media in selected Boot device"


Seeing it didn't find a drive to boot from, the computer was rebooted to enter the boot menu F8. Here the SSD shows up, with Windows 10 booting and running without problem after choosing the drive from the menu.

But for every reboot, the same message appears, requiring the boot menu to be used. I've tried reconnecting the SSD, but nothing changes.


Once booted into Windows 10 everything works perfectly fine. The computer can run for hours and hours without problem, and the new graphics card did wonders in games. In the Disk Management tool in Windows the SSD looks all fine, with the EFI System Partition showing up as it should.


Not having to enter the boot menu every time the computer is started and being able to reconnect the old HDD preferably using it as a normal drive without an old OS installed on it this time would be preferable. The fact that the Corsair gaming keyboard isn't recognized at boot aswell, but only starts functioning sometime into the OS startup, which requires the use of a "simpler" keyboard only to enter the boot menu, adds to theinconvenience. For the latter problem I've tried using BIOS mode on the keyboard, but that didn't help.


To fix the main problem I tried running the Startup repair tool from the Windows installation media. The tool reports that all is working fine once it's done. But nothing has changed when the computer is rebooted, the error message above appears again.


I know I can run the repair commands manually from the command line from the repair tool to fix things like a broken Windows boot manager, but I haven't tried it before. I don't want to head into this before seeking some guidance, especially since it's not my computer and there is no backup of the SSD yet, since a backup can be done now that we can boot to the drive. I've found different guides using differenent command line programs, like Diskpart and BCDBoot, but few talk about whether there are any risks involved with running those commands or not.

What are your suggestions to fix this problem?


Thanks in advance, it will be highly appreciated of the owner of the computer.

Can't boot from DVD drive

Is your controller in RAID/AHCI modes? If so, the DVD drive will be listed as a separate device in the list of available boot devices, not as "CDROM". Remember that when setting boot device priority. Otherwise, read the manual to see which hotkey during POST brings up the boot menu that lets you select which device to boot from. Even here, the drive will be listed separately, and not as "CDROM".

Bios will not boot from SSD

So it's been a LONG time since ive been on these forums, but I ran into a little problem that's got me stumped.

I just bought a 240GB PATRIOT Pyro SD to put my OS on.
So I backed up all my important info to an External HDD. Formatted my current 1TB WD Caviar Black that I had my current Windows 7 on. And went ahead and installed Windows 7 on my new SSD.
All was fine and dandy till I began installing drivers on Win7 and would need to reboot, it would come up with a message to Reboot and select proper boot device. So I went I to my boot options set my DVD drive as 1st boot and my SSD as 2nd boot, same message came up.
So just for laughs I only set 1 boot device as my DVD and had my Win7 install disc in the drive, it would come up with the message to press any key to boot from the DVD drive. But I waited it out, and for some reason it would boot straight into windows. Problem Solved? No
I just recently had to restart again, and now it won't boot into Windows anymore. I tried setting the SSD as first boot, nothing. Tried the DVD drive as first and the SSD as second, nothing. I just can't figure this mess out.
I'm running an ASUS M4A78-E mobo, and trying to get my 240GB Patriot Pyro SD to boot. Just so confused as why it worked, and now it doesn't.
