Press the bios boot button for your motherboard while powering up and then change the order in the bios.

do motherboards still have reset jumpers?

What's the motherboard model number?

Boot drive change would not lead to no output, it would show an error for no bootable media found. Did he unplug monitor? Check if its in gfx card and not the mobo hdmi port if so. You will always be able to get to bios if your mobo is alive.

Just an fyi. Mobo swaps can be a pita sometimes. I had to modify windows registry files via command line from bios on the new board to get it to boot for the first time when keeping everything else the same swapping all parts over. Cant remember if that was windows 7 or 10 though but i hope they made that better.

You can get in the bios even if you don't have a hard drive installed.

When you first power it up, watch for a message at the bottom of the screen that will tell you which key to press, sometimes F1 or Delete, but have seen F8 as well.

Bios boot order messup is no big deal, it will still POST it just will tell you NO BOOTABLE Hard Drive found.

CTRl - ALT - DEL, let it reboot, go back into BIOS, fix boot order, then Save, Restart and it should boot your OS.

If you don't have output to the monitor you have something else going on like a loose or unplugged monitor cord, monitor power cord or loose video card.

BIOS boot order is just choosing which HD, USB, CD Disk to boot for primary and secondary, has no correlation to the No Output which is the monitor telling you, that you have no incoming video signal...

And changing the MB, will most likely mean a new Windows install...

You don't need a new motherboard. Don't complicate your issue by doing that.

Do as the others said - get into bios as step one.

Also I've hand funkiness trying to get into bios when my monitor was plugged into a graphics card. If that's the case plug the monitor straight into the mobo and unplug the graphics card.
