I installed a WD 1TB Blue Edition 3.5" SATA3 Internal HDD as a second hard drive in my PC (Windows 7).
I formatted and partitioned it and it worked fine.
But when I restarted my computer a few days later, I received a “Reboot and select proper boot device” error.
I went into BIOS and made sure the boot devices were in the correct order (with Windows Boot Manager as first). They were. I also tried disabling every boot device except WIndows Boot Manager. I kept getting the error though.
My power supply is 400W which I think is adequate. I have also tried removing the drive and re-installing, but keep getting the same error.
Any ideas appreciated.
