Reboot and Select proper Boot device

AaronH9 · 14 Apr 2020 at 15:46

Hi,

I run my OS (win7) my an SSD, but recently tried to partition an HDD so that I could boot from windows 10 off the partition. This did not work and I have not been able to use my computer properly since. I have disconnected the HDD from the motherboard to prevent it from interfering, but even with this disconnected I’m in a constant state of crash/BSOD followed by the message, “Reboot and Select proper Boot device”, I’m even unable to access boot menu and BIOS as my keyboard will not work during the boot phase (it is still lit up though). Occasionally the computer will boot only for it to crash again within a minute or so of turning on. Any help would be greatly appreciated.

Thanks

Try clearing cmos
Or take the bios battery out for 10 minutes

I’ve just tried this but my keyboard still isn’t working so I’m stuck on the screen saying the BIOS has been reset, how do I want to continue.

Thanks

Try a USB2.0 port if not already. Some gaming keyboards have a BIOS function switch on the back which should make it more compatible at boot. Failing that you may need to try another keyboard.

Thanks, I’ve used the BIOS function and managed to get the computer started however within a minute again I’ve had BSOD. However I’ve managed to get into the BIOS upon reboot, any suggestions now?

Cheers

It sounds like you may need to repair the boot sector.

Thanks, I’ve just looked and my only boot option is my disc drive, so do you think I may need to fix my MBR?

Is your SSD showing as connected in BIOS at all?

no, not at all all I’m getting is “P3: HL-DT-ST BD-RE BH10LS38”, which I believe is my disc drive.

That's correct. Right, if the BIOS can't see the SSD at all that's an issue! I would re-connect both the power and SATA cables on the drive to rule out a bad connection.

I’ve reconnected the cables and managed to get in. However I’ve got BSOD again and the SSD has disappeared from the boot options.
