The list has been separated based on the most popular remedies reported by users who have encountered this issue. Let’s get started.

Following are the methods to fix inaccessible boot device BSOD error in Windows 11:

Method 1: Look for the loose cables

If you’re a desktop user, this method might be useful. If you’re familiar with PC hardware, you can examine the inside of your computer’s cabinet to see if all of your cables and RAM modules are correctly attached. Just to be sure, unlatch the wires and reattach them where they were. Keep an eye out for dust while reconnecting the cables and try to blow it out if any has accumulated on the connection ports.

Later, restart your computer to verify if the INACCESSIBLE_BOOT_DEVICE problem still exists.

Method 2: Run DISM (Deployment Image Servicing and Management)

Step 1: Using the manner outlined above, open Command Prompt.

Step 2: In cmd, type the following command and press enter:

DISM.exe /Online /Cleanup-Image /RestoreHealth

Dism /Image:C:\offline /Cleanup-Image /RestoreHealth /Source:c:\test\mount\windows

Dism /Online /Cleanup-Image /RestoreHealth /Source:c:\test\mount\windows /LimitAccess

Note: Replace C:RepairSourceWindows with your repair source’s location (Windows Installation or Recovery Disc).

Step 4: When the DISM operation is finished, type sfc /scannow in the cmd prompt and press Enter.

Note: In the above command, C: is the drive on which we want to run check disc, /f is a flag that tells chkdsk to rectify any faults on the drive, /r tells chkdsk to look for damaged sectors and perform recovery, and /x tells check disc to dismount the drive before starting the procedure.

Step 3: When it asks if you want to schedule the scan for the next system reboot, select Y and press Enter.

Step 4: Restart your computer after exiting the command prompt.

Method 4: Disconnect External Hard Drives

In the event that an external hard drive is connected to the computer at the time of boot, the Inaccessible Boot Device error can occur. This may result in a conflict in the order of boot preferences, causing the main boot disc to lose precedence. In order to solve this problem:

Step 1: Disconnect every external storage device from the PC.

Step 2: Restart your computer now.

Method 5: Connect Drives Properly

One more thing to keep in mind is that connections might loosen over time as a result of usage, heating, shocks, or poor wiring. The connectors may be defective in some cases, resulting in inaccessible boot device problems.
