Windows server 2016 repair loop

a company that we use for back up installed their software, after a reboot our HPE gen 10 server will not boot back into Windows.  The boot cycle eventually ends up with the Choose an Option (continue/troubleshoot/turn off) screen.  ALL choices lead to a reboot.

the server has a raid 10. Looks like it is configured correctly.  When I look in the Marvel Bios utility, there is no indications of disk failure.

When I put  a bootable windows server usb and try to boot/install/repair it takes me back to the choose an option screen/reboot.

I was called into this office tonight.  There is no backup.  They have important data on the server. They need to be open for business on Monday.

Can someone give me suggestions?

Hello ThereSystem AdministratorCommented:
Just a few suggestions:

It might be caused by third party application... Have you installed any recently? If yes, uninstall it and see if the issue persists.

I suggest you to enter Safe Mode with minimal requirments. Also use Diagnostic startup and then Selective startup with no option selected when booting. (msconfig option...) If the issue disappears, it's a sign that OS, software or drivers are corrupted.

Faulty HDD might cause this too. I suggest you to test your RAM na HDD (quick scan and then deep scan). I you see any errors you should consider replacing it.

Also disable "Fast Startup" in the shutdown options of the Power Options menu.
Start -> Settings -> System then select Power & Sleep and scroll to the bottom and pick Additional Power settings, this opens the Power Options menu. Now select "Choose what the power buttons do" and then "Change settings that are currently unavailable". Scroll to the bottom and under Shutdown Settings untick "Turn on fast startup (recommended)".

Update BIOS or reset BIOS to its defaults.

Run CMD as admin:
>DISM.exe /Online /Cleanup-image /Scanhealth
>DISM.exe /online /cleanup-image /restorehealth
>sfc /scannow
If this will not help...

Press shift +  Restart.  After your PC restarts to the Choose an option screen, select "Advanced options" and then "Troubleshoot". Select "Advanced options" and then select "Command Prompt". Then type:
bootrec /fixMBR
bootrec /Fixboot
bootrec /rebuildBCD

Update your HDD drivers + all drivers for sure.

Turn off your AV or graphics adapter.

If you enter Safe Mode... does it happen too?
If yes, bootrec repair commands might help you.
Have you reinstalled the OS recently?

I can't boot into safe mode by pressing f8.  Is there any other way I can run HW diagnostics? (ram, hdd, etc)

Also, another tid bit of info:  before this happened there was a slight issue (?) with the server.  It fully functioned so I wasn't worried about it.  The server would try to boot would try to boot from Ethernet adapters, then hang up on "press any key".  To resolve (the 2 times I saw it) I would simply reboot,  wait until hp slpash screen/select f11,  select boot device/marvel raid and it would boot into windows fine.

Should I try to update the bios? I am grasping at straws here.  It is really unfortunate the office manager waited until the last possible moment to back up! :/  But nows not the time to blame, its the time to fix!

Yes... we use Hiren's Boot Live CD (make one) to test all hardware.

Are you able to run CMD?
What apps are running on this server?
If your server won’t boot (hence the need for F8) then you can boot off of a Windows Server install DVD and select REPAIR YOUR COMPUTER option, the Troubleshooting, then Command Prompt.

You don't seem to have experience with that kind of situation. It will be hard if not impossible for you to follow steps that you see here and time is not on your side. You have some options:

-backup your data and reinstall ->find out how to boot a setup on your machine
-seize the error and (eventually) deactivate the service that causes it ->find out how to see and interpret a bluescreen of death and how to manipulate the windows registry of unbooted systems)
-try and activate a restore point (if restore points were in use) ->find that out and also how to revert to a previous R.P.
