Hello! I hope this is in the right place.

I have a KVM switch hooked up to my laptop and home PC. When the KVM is directed to the PC and I am trying to boot up, but it wont boot up. It does not get past the Bios. In fact, it doesn't even get to the Bios. I have to set the KVM to the laptop and wait for the PC to get to the windows logon screen before I am able to switch the KVM back to the PC. I knows the reason this is happening is because the PC doesn't recognize the KVM device. How do you make the PC boot up normally, without having to direct the KVM switch to the laptop?
