No display after changing boot mode to UEFI boot. What happened?

I was having trouble installing Windows 10 onto a hard drive that I was going to use with my robotics team’s Dell Desktop.

I noticed in the boot settings that the boot mode was set to Legacy and I figured in the moment that the Legacy boot mode was preventing me from installing Windows 10 successfully.

Right after setting the boot mode to UEFI the computer shut down completely. I powered the computer back on and to my surprise there was no display whatsoever on the monitor. However, all of the internal components appear to be running as the system’s fans are running and it is generating heat.

What happened? Did switching to UEFI boot mode break this poor computer?

System info:

Dell Precision T3610

32 GB RAM

500 GB HDD

Intel Core Xeon

Update (10/26/2018)

@alecm @jayeff I tried doing both your suggestions without any luck. The fans will run and the unit will generate heat, but there will be no video. I skunked on this one.

There's also usually a small jumper on the motherboard labeled "reset" or "CMOS reset" that will do the exact same thing, even when there's a battery in the PC. All you have to do is short the two pins with some metal object like a screwdriver when the computer isn't on.

Hi @ajcooke01 ,

Have you got a Win 10 USB recovery disc?

If so try to boot using it.

I know that you cannot see BIOS to alter boot options but try anyway with the HDD disconnected and see if it "finds" the USB recovery disc to boot from by default

If this works (desperate times call for desperate measures)in the WRE go to Troubleshoot > Advanced > UEFI settings and see if you can alter the setting back to Legacy mode and then go from there.

Again this is only a wild attempt to try and get it going as I think that you may have "bricked" it.

Hi @ajcooke01

Try removing the CR2032 battery... do your workstation has add on graphic card? test with another known working one... if there is multiple RAM installed, remove them and boot it with ONE stick at a time

@salmonjapan I tried removing the CR2032 battery and a new graphics card. I’ll try the RAM suggestion though.

There can be issues that exist between particular UEFI display output configs and certain monitors.

I've had issues in trading floor support with HP Z workstations and both basic Dell 22" screens and large Samsung ultrawide 34". Something again recently with a Z series workstation and big 2x 48" screens (Dell I think).

I don't know the specifics of what this is but the solutions are:

A) Run in legacy mode

B) Boot up with the display cable removed and then put it back in once the system has reached the OS so that it doesn't run into the UEFI conflict

C) If you have onboard graphics, add in another graphics card. This isn't helping the issue, what you'll still see is a blank screen during POST and inside the UEFI settings screens (so you need another monitor if you ever actually need to access these things), but it might be enough to stop machine from calling a POST/boot failure and freezing.
