Reboot and select proper device

[Dekuuz]

I just upgraded my cpu and mobo and when using my old hard drive I can't get into my computer anymore. I tried booting from Windows Boot Manager and it says Getting Devices and immediately blue screens. I try SATA1 and it just does the Reboot and select proper device. I am worried. Any help?

 

I'm using a i5-9600k with a Z390-A pro MOBO.

When you change the motherboard you effectively change the computer.  Windows is looking for the old stuff.  Will it post?

What do you mean by post?

Post means get into bios.  You’ll need to hold down or spam some keyboard key right after hitting the power button. It’s often delete, f11, or something like that.  Generally varies from mobo to mobo.  You can actually do it without a hard drive.  The “os” on the end of bios stands for operating system.

I can get into the BIOS but I can't get past the Reboot error or the blue screen.

Welp, sometimes you can boot an existing install of Windows on an entirely different PC, but I guess it isn't playing nicely here. Your best bet is to either reinstall Windows on another drive than grab all your stuff from the old one, or go back to at least your old board, then backup your stuff and reinstall Windows with your new motherboard.

I guess I'll have to do that then
