Follow the procedure to remove the author’s update files.

Step 1: First, boot your computer with “USB Flash Drive“.

Note – If you are having trouble booting through a USB boot device, you should first try changing your BIOS settings so that you can boot directly and successfully from USB. The BIOS setup can be accessed by powering up the compatible PC and pressing any function keys. We recommend that you follow the manufacturer’s cooperation to avoid further mistakes.

Step 3: Proceeding, click on the Troubleshoot option in the Advanced Startup panel.

Step 4: Click / tap the prompt command with different options on the next screen.

Step 5: The next task is to remove the SessionPending registry key. To do this, type the given series of commands on the blinking cursor and press Enter after each one.

reg load HKLMtemp c: \ windows \ system32 \ config \ software

Reg Delete “HKLM tempMicrosoftWindow CurrentVersion Component Based ServicingSessionsPending” / v Exclusive

dism / image: c: / remove-package / packagename: PACKAGE-IDENTITY-NAME / scratchdir: c: temp packages

After successfully removing the update, restart your computer and the error will not appear on the screen. The computer should now boot normally.

Solution 2: Scan SFC to check system files.

Windows 10 has a default system file checker to fix inaccessible boot device errors. It actually repairs broken system files as well as restores damaged files. The steps are as follows:

Step 1: Type cmd in the search box on the taskbar. While the command prompt appears at the top of the search results, right-click it and select Run as administrator.

Step 2: On the black panel, type the following command on the flickering cursor and press Enter.

Solution 3: Check for faulty hard drives.

A faulty hard drive often causes a “0x000000007b blue screen of death” or alternatively an inaccessible boot device malfunction. If it is possible to log in to the PC, follow the instructions below to resolve the error:

Solution 4: Enable AHCI mode in BIOS.

Today’s modern PCs have a BIOS for booting as well as checking the hardware components of the system. It also loads the alternative operating system boot loader from the mass memory device. However, if you enable AHCI (Advanced Host Controller Interface) mode in the BIOS, the error can be fixed. To do this, you need to follow the steps below:

Step 1: Enter the BIOS by pressing F2 or delete the function keys while the computer is booting.

Step 2: After entering BIOS, go to the Advanced section. Now turn the configured AHCI mode option on.

Note – As an option, you can change the AHCI mode control to auto.

Step 3: Press the Save button and restart your computer.

Therefore, cross check of all connections and strict connection can also solve the problem. Sometimes using different ports on the motherboard to connect a hard drive fixes the same thing. You can do the following.

Step 1: Shut down the computer by going to the Start menu and clicking on the Power icon.

Step 2: Turn off the power supply to the computer.

Step 3: Disconnect all cables and accessories. Replace the port connecting the hard drive with the motherboard.

Step 4: Plug all the cables after the same scheme as before.

Step 5: Re-open the power supply and turn on the PC.
