High troubleshooting for Stop error 7B or Inaccessible_Boot_Device

1] Verify that the boot disk is connected and accessible.

Boot into Modern Recovery, and then open Program line Prompt. Here we will figure out if iron heel disk is adjacent, and accessible.

Microsoft recommends that you accomplish diskpart, and then runlist diskcommand. This command will reveal the list of physical drives that are attached to the computer. If they are connected, you should receive details just ilk the image below:

Diskpart List Disk Command

Note:

UEFI port will suffer an star () in the **GPT* column.
BIOS port will not own an asterisk in theDyn column.

If the list disk overlook lists the OS disks right, die hard the list vol command in diskpart. It should generate an output similar to the adjacent see.

list vol diskpart results

The image above displays Volume 1 as iron boot disk. If on that point is no similar listing, you may have to either repair the iron boot partition on your own or connect with the service center of the OEM.

2] Verify the unity of the Boot Configuration Database

Boot Configuration Database, a refilling of Boot.ini file, contains boot configuration parameters and controls how the operational system is booted. If there is any corruption or misconfiguration, we will have to fix it. Before that, let's diagnose if there is a trouble.

Boot into Advanced Recovery, and so staring Command Prompt. Type bcdedit and smash Enter. You should results like in the fancy below. UEFI and BIOS rich person their slight differences.

In the results, notice if the identifier is set to default, and the device & way of life, point to the correct partition. It can lonesome ensure that the "winload" file away loads correctly. If this is not what you see, we will have to desexualize BCD.

The BIOS interface testament not have whatever way, simply the drive. But the UEFI interface volition show a rank course in the gimmick divider parameter.

a] Circle default device divider

Take the backup of BCD using the commandbcdedit /exportation C:\temp\bcdbackup.To restore at a later stage, you fire replace /export with /import.
If the device under {default} is wrong surgery missing, move the bcedit command with the set choice bcdedit /arrange {default} device division=C:

b] Re-create the BCD totally

If you receive an error message which saysThe boot constellation information salt away could not be wide, The system could not find the Indian file nominative, then executebootrec /rebuildbcd along the Command Propel.

c] Verify Placement of winload and bootmgr

Bootmgr(Windows Boot Coach) and Winload (Windows Osmium Loader) are part of boot phases. PreBoot loads Boot manager, which in turn loads Winload. If the files are not in their correct places, the boot process will be cragfast. Here are the locations of the files-

bootmgr: %SystemDrive%\bootmgr
winload: %SystemRoot%\system32\winload.exe

Before going up, make sure to make a backup of all the contents low theSYSTEM partition to other location. Information technology will come in handy if something goes wrong. Use the Command Ready to sail to the System drive, and produce a folder where you can back dormy everything.

Pilot to these directories, and unhide files usingAttrib -s -h -r command. If they are not in their place, let's reconstruct IT.

Bcdboot <**OSDrive* >:\windows /s <**SYSTEMdrive* >: /f ALL

Where "OSDrive" is where Windows is available, and the system drive is where the bootmgr resides.

Reboot and see if this has helped.
