How to open to the BIOS setup on a Z2 G8 from Windows 10

[testlab]

It has taken me three hours of screwing around to figure out how to access the BIOS menu so I can change the device boot order.  NB: using F10 or ESC at boot time DOES NOT WORK.  The same question was asked and incorrectly answered herein: https://h30434.www3.hp.com/t5/Desktops-Archive-Read-Only/bios-access-f10-doesn-t-work/td-p/3637252. ...Also the official HP "Maintenance and Service Manual," Document Part Number: M54510-001 says to use F10. Worse than useless.

Here is what worked for me. Your mileage may vary.

With Windows running:
> Start menu, enter: advanced startup options
--"Change Advanced Start Up Options" shows
> Click "Open"
--Settings.Recovery panel displays
Under "Advanced startup"
> Click "Restart Now"
--Blue restart screen shows
--"Choose an Option" screen shows
> Click "Troubleshoot"
> Click "Advanced Options"
> Click "UEFI Firmware Settings"
--"UEFI Firmware Settings" screen shows
> Click "Restart" control (small white box)
--PC restarts from black screen
--UEFI "Start Up" Menu appears
## This is the new version of what you used to see after hitting F10, ESC, etc. as your PC booted up.
## The following steps get you to the BIOS settings - there is a lot more.
> Select and click BIOS Setup (F10)
--BIOS options display
> Click "Advanced" at the top of the screen
--BIOS Advanced options display
> Click Boot Options
## You can now change Boot options, including the order of devices to check for the Bootup code.

Thanks!  I was not aware of that functionality.   I tired it on an Area51 but did not get bios.  I got the blue screen options which is actually useful. Save the trouble of booting a windows repair USB.

Did the above show up on your HP?

FWIW, it can be very difficult to capture the BIOS on modern system with fast boot.  Depending on what key is pressed up to 6 scan codes are sent from the keyboard.  If the system is not ready to receive the codes the first ones may  be dropped and the remaining captured but not interpreted correctly.  From there on the keyboard buffer is out-of-sync. This generally is fixed only by powering the system off and back on.  On those HP systems that recognize the ESC key it is best to use

the ESC key and not F10 and wait for the keyboard led to light up before starting taping the ESC key.  Just my 0.02₵ opinion.

Yes, that's what I saw too.

Because I used ">" in my original post, It looks like the client-side code for this forum chopped off the last half of my post, which lists the rest of the steps (I'd guess this forum code is a buggy Wordpress hack.)

**bleep** - I do not see the last half of my post displayed, but it is still shows as encoded HTML for a second when I open the edit window.  How do I file a bug report for this?

I think the spam filter caused problems.

Check your messages for one from me.

Here is the procedure as an image.  You'll have to transcribe it to text as this forum will not display it as written.

It appears the elves have tweaked the forum system, as I now see all of the content I originally posted.
