Not able to boot on any device

[Johan7311]

Hi

My sons computer booted during play and restart stopped at "No boot device found".

I suspected HDD failure but both quick and full diagnostic test passed.

I've tried to boot on multiple devices (a working HDD from other computer, 2 different Win11 install USBs, a BIOS update USB but no...I start with F9 and is able the choose boot device but just end up with blank screen and cursor blinking in upper left corner.

Any tips on how to proceed is much appreciated.

Hi @Johan7311 

Welcome to the HP Forum.

The PC has power, you have video and USB support, and you can get to the HP UEFI Startup Menu. But the PC chokes when trying to boot to a W11 system disk or W11 USB boot media.

And all HP Diagnostics tests passed. Have you run extensive tests?

There is something wonky going on if you can access the HP Startup menu but the Boot Menu is useless.

Try "F10". Reset the BIOS to defaults if possible. Or you could also try removing the CR2032 MB battery to reset CMOS.

Disconnect all unnecessary peripherals to eliminate this variable.

This is a strange scenario.

It sounds like a BIOS issue or you have a MB problem. It could also be something else.

Thank you so much Bill_To!

I have replaced the CMOS-battery, removed/switched RAM-modules (multiple restarts with different setups) but problem persists. I feel I get a bit further though sinc it "tries" to boot, at least that's how it "feel". (see video)

It smells like hardware issue. I think I have a spare GPU...is that next thing to try to replace? Or should I just accept that it is a motherboard issue?

Hi @Johan7311 

My pleasure.

Good idea to install a new MB battery. This would reset CMOS.

Thanks for the video. It looks like the PC attempts to start Windows (spinning wheel) but you get a blue screen. I see a blue screen Machine Check Exception error which is similar to a WHEA error.

A WHEA error usually points to a heat or a hardware problem. It could be a Windows driver problem but this would be unusual. The PC will not boot to any media. This appears to suggest a hardware issue vs a Windows problem.

You may have look at each component to find the cause. Any component connected to the MB could be failing or has failed. Trying a different graphics card would be a starting point. Try onboard graphics if the CPU supports this.

The system drive or power and data connections to this drive could be involved. Disconnect this drive. Try to boot to other media now.

You should methodically reduce the PC in minimum config, check for a change in behavior as you go. Eventually you will be down to the CPU, one stick of RAM, and onboard or discrete graphics.

You may have to swap in many replacement components down to the CPU or MB to find the bad part.

It is sometimes cost effective to have a local PC Tech diagnose the problem.

Hi again...

Just wanted to give some feedback. I'm a bit ashamed but I came to notice that the failed disk was a NVMe...so it was installed ON the motherboard. I  can't explain why I didn't notice this before but of course THAT was the failing hardware.

So when I removed it I was able to boot to Windows installation and reinstall computer. 

My bad... 🙂 

Thanks for the help!
