How to escape INACESSABLE_BOOT_DEVICE bsod loop.

Hi, I just tried to set up dual windows boot on 2 internal ssds and now my laptop is stuck in a bsod loop.

I got a new 1 tb ssd and wanted to move windows on that one. I decided to do a fresh install to get a Clean c drive so I installed windows 11 to a partition in the new ssd planning to remove the pld one later and rearranging some files. Then I tried to boot from that ssd and it gave the error: iNACESSABEL_BOOT_DEVICE

Now it's stuck in this bsod loop and I can only access bios.

Attempts to fix:

  1. Reset bios to defaults
  2. Tried to enter WinRE through all methods but none worked
  3. Made a bootable USB but it only reads its own partitions and not the ssds in the process of installation and revocery attempts through cmd
  4. Removed each disk one by one:

Remove oem ssd: no boot device found

Remove new ssd: doesn't go beyond POST and BIOS, just restarts before attempting to start windows.

  1. Disabled fast boot and VDM

I have checked the bios and it doesn't have the option to select the drive to boot from but just USB and windows boot manager which leads to the problem. If there is some setting that can reset the configurations of WBM please help me identify them in the bios.

Due to the fact that I can only enter the recovery mode in the USB and it only uses that drive, many troubleshooting command line tools are unavailable.

Device specs:

Acer PHN16-71

OS: Windows 11 24H2 (last working one)

BIOS: v1.18

Edit: Update

Tried to install windows to the new ssd after loading the storage controller driver(irst).Got into self repair and formatted the new ssd(lexar nm790) to gpt ntfs and made a simple partition. Windows installation Works till the end and says that an error occurred, need to restart. After restart there is another windows boot manager option in bios but it results in the same error.

Now that I can atheist access my ssds from the command line and see the working windows files if anyone knows the commands needed to change the boot drive or load windows from a specific drive please help.

Update solution:

Make a bootbale USB with Windows using rufus

Choose it as the primary boot device

Navigate through the installation until asked to select drive

Click load drivers and load your storage controller drivers from providers website

Delete all partitions on the drive number to install to

Complete installation process

I don't know what caused the initial corruption installation to begin with.

Windows for home | Windows 11 | Windows update

    Well yes I wouldn't be here if it was that simple. Due to the working windows installation not working at all, the storage controller drivers are also not installed( Intel irst) I installed them and formatted my new ssd using diskpart to install windows. I set it to gpt, ntsf, made a regular partition and tried to install windows to it but it stops right at the end saying it failed and I need to restart into this again.

    After these steps another windows boot manager shows up in the bios but it gives the same error I get from the installation. The new ssd is lexar nm790

    hi,

    What is the manufacturer of your device? I had that issue with my Asus laptop. I changed the Intel VMD Controller settings to off or disable it in bios. That fixed my issue. Please try that first.

    Hello,

    Thank you for posting in Microsoft Community forum.

    Based on the description, I understand your question is related to bsod.

    Check that the boot order is set correctly in the BIOS and that the new SSD is selected as the primary boot device. Ensure that all hardware components, including the SSDs, are properly connected and seated in their respective slots.

    You can try boot from a Windows installation media and select the "Startup Repair" option to automatically fix any startup issues. If you have a restore point created before the issue occurred, you can use System Restore to revert your system to that point.

    If none of the above steps work, you may need to reinstall Windows on the new SSD.

    Have a nice day. 

    Best Regards,

    Molly
