Windows 10: Windows 10 Pro Inaccessible_boot_device after BIOS upgrade and reset

Hi all, after upgrading my computer BIOS from F6 to F8, my computer has been experiencing a BSOD called Inaccessible_boot_device. The only thing that fixed it back then was system restore. Curiously enough, I ran that system restore with no drives plugged in except my system SSD, so when I turned off the computer and went to plug in my NVMe it was crashing again with Inaccessible_boot_device. On my F6 BIOS, when I added my NVMe there was no such BSOD. Once again I restored my computer back to a working state by using system restore.

Now my problem is that I had a power outage 2 days ago and my motherboard was having issues booting up, it would boot loop up to debug code 32 "CPU PEI Initialization". A hardware change can get it working again. For example, I had code 32 so I removed a stick of ram. Code 32 again? I add that stick of ram back in. This phenomenon only occurs on the F8 bios and when I downgrade to F6 it is gone. Clearing CMOS and unplugging everything does not solve this issue. However, I did clear the CMOS 2 days ago after I had the power outage before doing the hardware change fix.

So now my motherboard boots up again, and I have that same BSOD Inaccessible_boot_device. I thought, no problem, I will just use system restore. Unfortunately, there were no restore points :/ So I went on through trying numerous other methods to get working. Such as making sure ACHI is correctly configured in BIOS, running SFC and DISM, and rebuilding BCD. The error still persists. Curiously enough, if I try to boot the system on the F6 BIOS the BSOD does not get displayed but instead crashes on the UEFI loading screen with no explanation. I know that it is a BSOD because if I change crashcontrol autoreboot to 0 in registry, the system just stays stuck on the Gigabyte logo with no spinning circle, instead of rebooting.

Additional information would be that my system normally boots and reaches the login screen in 7 seconds, but now it takes 15 seconds just to get to the BSOD.

A person with a similar problem with me and a Gigabyte motherboard solved this problem by unplugging everything including the CMOS battery which supposedly cleared some NVRam variables which allowed him to boot again. I did the same thing and waited up to 10-15min., but it is still a no go. Also curiously enough, is that even after all this clearing CMOS stuff and unplugging the battery, some old EFI boot entries still exist. This makes me think that the NVRam is not getting cleared. I am not sure how to go about doing that.

A fix that I am almost certain would work would be restoring the registry from RegBack, however that folder is empty since Microsoft disabled automatic backup of the registry.

My system generates no ntbtlog.txt when enabling boot logging; additionally, there are no crash dumps or mini crash dumps being made.

I know a clean install would work and that is probably what I will have to do if nothing else prevails. If anything, I am very curious as to what this problem is since it is a very strange bug check considering the circumstances. If anyone has any information to what keys and values in the registry might cause this problem, I would greatly appreciate it.

How to fix INACCESSIBLE_BOOT_DEVICE - Windows 10 Pro

If you can get into safe mode, go into device manager and uninstall any hardware listed under IDE ATA/ATAPI controllers. When you uninstall the controller, check the box for delete the driver software for this device. Then try to reboot into normal mode.

 

Windows 10 upgrade problem, no input accepted

I really hate having to come here and ask for help, but I really am stumped. It hurts my geek pride. I have a PC with fairly modern hardware in it. It has a p8p67 pro in it. I have tried upgrading windows 10 on it twice now. Both times I have had the same result.

After windows finishes upgrading it goes to the log in/set up screen. I can't do anything. No keyboard or mouse input is accepted.

I will list some, or hopefully all, of the troubleshooting steps I have tried:

• Move keyboard and mouse to different USB ports.
• Try different keyboard or mouse.
• Restart computer, repeatedly.
• Google for related issues.
• Update Bios, because why not.
• Create boot media and revert to windows 7.

The windows 10 system restore boot media works fine with keyboard and mouse. All USB ports work in windows 7. I don't know what is wrong. I suspect that windows 10 is lacking a driver of some sort, but since the computer accepts no input I have no way of checking for which driver let alone installing it.

Please help me figure this out. If I have to revert back to windows 7 again, I am not going to get it upgraded to windows 10. Thank you in advanced.

 

Moving to RAID 0 - INACCESSIBLE_BOOT_DEVICE


I am converting an existing Windows 10 Pro laptop to RAID 0 - and I keep getting to the final boot where it says INACCESSIBLE_BOOT_DEVICE. What am I doing wrong? The laptop has two 1 TB Samsung 850 SSDs that are identical. Laptop is a HP Zbook 17.

Here are my steps:

1. Made a good System Image of C: drive on separate external SSD drive connected by USB. D: drive didn't have anything on it to be saved.
2. Used Win 10 Pro DVD to delete all partitions/format drives.
3. Went into BIOS and changed from AHCI to RAID, and also to turn on ability to do Control-I to get to Intel RST ROM.
4. Rebooted, did Control-I, created a RAID 0 of the two disks.
5. Rebooted, installed Windows 10 fresh. Verified it would reboot on its own.
6. Rebooted, went into Repair on Windows 10 DVD. Selected external SSD image to do image restore from.
7. Rebooted - verified on Control-I that the RAID 0 array is listed as "bootable"
8. Rebooted - get INACCESSIBLE_BOOT_DEVICE.

The place it dies - I see the little Windows 10 blue window, and the spinning circle at the bottom - then I get the blue screen with the message.

I think I listed everything I did - what am I missing?
