Windows 10: can't enter bios menu after system image restore

I have an Asus UEFI mobo on my custom-built desktop, a few months old.
B150M-K D3
It has American Megatrends firmware

Today I restored my system from a macrium reflect system image. I went back only 2-3 hours in time.
After rebooting, windows started up fine.
But the bios reverted to its default settings, although I had previously tweaked it a bit.
What's more, I can't get to the bios menu at all. I mash the delete key at startup, and I just see a blank screen. Even an hour later, just a blank screen.

This happened to me not so long ago, but that time, the bios screen did eventually appear, and with a little patience I was able to tweak the bios again. But this time it is more stubborn.

I also feel that the boot process is slow. I see the asus advert, and it coughs a couple times and drags on until I get to the windows boot menu where I choose if I want windows 10 or macrium reflect recovery environment.

I very often restore from a system image, and every time, it makes a new bios boot entry. I have dozens of boot entries by now in the bios boot menu. Maybe that's causing a problem?

edit: the fan is unusually loud, although cpu usage is low, just 0-2 %

Update Install, "Green Screen", Windows 10, lock

Do you have a system image and system repair disk? Perhaps you have some kind of system recovery option in your bios? My HP is F11 and it will give me several options to try from restore from a point to restoring an image and reset. It should be there
in your bios menu. I assume all pc makers do this not just HP.

Access to System image backup folder blocked when trying to re-image my Windows 10 PC

That worked, and I was able to access my Buffalo Tech NAS and the system image I was trying to use. When I try to do the restore, I now get the error message "Windows cannot restore a system image to a computer that has different firmware. The system image
was created on a computer using BIOS and the computer is using EFI." I got the same error when I copied the system image folder over to my data drive. In fact, I created the image on the same computer (UEFI) I'm trying to restore back to. I guess the SW erroneously
thinks the Buffalo Tech NAS BIOS is the operative creation BIOS. Any ideas? Even though Win 7 backup is designed to save (as a valid option) system images to an NAS over a local (wired) network, the backup images are useless because they can't be used for
a system restore.

 

Try holding down shift key when clicking Restart from the power icon. Go through the advance troubleshooting menu until you get the option to change UEFI bios settins (or something like that). Click that and it is supposed to restart into bios without you pressing any keys.

 

right. I tried that, but I still get the same blank screen staring at me.

 

You can also try holding down shift key when you click Shutdown from the power icon. That will override Windows 10 fast startup procedure. After the computer shuts down either remove the CMOS battery from the motherboard or short the pins for CMOS reset on the motherboard. Then restart and try to get into bios.

 

last time this happened, I tried the battery trick, but it didn't improve the situation. It still took forever to get to the bios screen.

 

Sounds like you have a motherboard/bios hardware problem not related to Windows 10. If/when you can get into bios, I would reflash it.

There should be a way to make a bios flash USB drive. I would do that. Then disconnect all the hard drives/SSDs from the motherboard and boot it with the bios flash USB drive inserted. ASUS should have instructions for that on their website.

 

sounds like a plan. Instructions say: Download the latest BIOS file and BIOS Updater from ASUS website and save them on the USB flash drive.
Okay, I got the bios file, but I can't find the bios updater. I see a utility called ASUS Boot Setting V1.00.22 for Windows win8.1 64bit&win10 64bit.
Do you think that's it?

 

This might provide more detailed instructions:

This file says it contains the EZ Update Utility:

the ALSuite you linked to does indeed have such a utility, but it works from desktop, not from flash drive. I looks to me like they don't have a bootable flash drive utility for my mobo.

 

Then I guess the best you can hope for is to reflash the BIOS from Windows.

 

any advice how to minimize risks?

 

A biggy, ALWAYS connect the computer to a UPS/Battery backup to assure a power failure or fluctuation doesn't interrupt the process which could result in a dead motherboard. If it's on a Notebook have a fully charged battery and leave plugged into the AC source.

 

then I'm okay, because I have UPS. I will try to turn off all security software, too, so nothing tries to get in the way.
