Part 1: What Causes the 'Inaccessible Boot Device Windows 11 After Clone’ Issue?

The inaccessible boot device Windows 11 after clone error can be attributed to various factors, each requiring careful consideration to pinpoint and resolve. Understanding the root causes of this issue is crucial for implementing effective solutions. Here are some common factors contributing to the inaccessible boot device after clone macrium problem:

  • Driver Incompatibility: When a system is cloned to another hardware configuration, driver discrepancies may arise. The absence or incompatibility of crucial storage or chipset drivers necessary for the new hardware can lead to an inaccessible boot device after clone to NVMe.
  • Incorrect Boot Configuration: The boot configuration may need to be appropriately adjusted during cloning. The cloned system might attempt to boot from an incorrect device or partition, preventing access to the required boot files.
  • Cloning Software Limitations: The choice of cloning software plays a significant role. Some applications may need to handle the cloning process more smoothly, leading to errors in transferring crucial system files. Compatibility issues and limitations of specific cloning tools can contribute to inaccessible boot device Windows 11 after clone problem.
  • UEFI/BIOS Settings Mismatch: Differences in UEFI (Unified Extensible Firmware Interface) or BIOS (Basic Input/Output System) settings between the source and target systems can lead to boot failures. Inconsistent configurations may cause the cloned system to be unable to locate the necessary boot files.
  • Partition Alignment Issues: Improper alignment of partitions during the cloning process can result in data corruption or loss of accessibility. Misaligned partitions may cause the operating system to be unable to locate critical boot files, triggering the Windows 10 inaccessible boot device after clone error.

Part 2: How to Fix the 'Inaccessible Boot Device After Clone’ Issue?

Encountering the inaccessible boot device after clone error can be a frustrating experience, but several solutions can help address the issue. Follow the below solutions:

Fix 1: Make the Cloned Drive as the Primary Boot Option

Making the cloned drive the primary boot option is fundamental in resolving boot-related issues after cloning. Follow the below steps to fix the inaccessible boot device Windows 10 after clone:

  • Firstly, you should restart your computer. When the startup screen appears, repeatedly press a specific key (usually F2, F8, F12, Del) to enter BIOS Setup.
  • Choose Boot and make the cloned hard drive the first boot option.
  • To save and exit the BIOS, press F10. Then, restart the computer to see if it can start successfully.

Fix 2: Verify if You Have Cloned the Incorrect Disk

By carefully verifying the source and target disks during the cloning process, you can eliminate the possibility of unintentionally cloning the wrong disk. This straightforward check can save time and prevent unnecessary troubleshooting steps, ensuring a more accurate and successful cloning process.

Here are the steps to check:

  • You must install the cloned hard drive on your PC.
  • Start your computer again using the original disk.
  • Launch Windows File Explorer and navigate to the cloned drive.
  • You should look for the "Windows" folder on the cloned drive. If you locate it, the inaccessible boot device after the clone error is due to another reason. If not, you most likely cloned the incorrect disk. Additionally, you must clone again to the hard drive.

Fix 3: Run SFC Command

System File Checker (SFC) is a built-in Windows utility that helps repair corrupted or missing system files. Running the SFC command can address issues related to system file integrity, potentially resolving the inaccessible boot device after clone problem. Follow the below steps:

  • Please wait until the computer restarts itself before using it. It will try to fix itself and pop up the screen below. Next, select "Advanced options."

    Advanced Option
  • Choose Command Prompt under Advanced Options > Troubleshoot.

    Command Prompt
  • To launch it, type sfc /sannow into the command prompt and hit Enter.

Fix 4: Run the CHKDSK Utility to Repair Bad Sectors

The CHKDSK (Check Disk) utility is another built-in Windows tool that can help address disk-related issues, including bad sectors that might contribute to the inaccessible boot device after clone problem. Follow the below steps:

  • You must start your system using the original disk.
  • In the search box, type cmd. Then, right-click and choose "Run as administrator."
  • After that, type "chkdsk c: /f /r" and hit "Enter."

    CMD Command
  • The next time the system restarts, you will be prompted to choose whether you want the CHKDSK tool to rerun the scan. To answer "yes," just type y, then hit Enter.
  • It might take some time to finish after you restart your computer.
  • Once the process is complete, you must re-clone Windows 10 to the hard drive.
  • Restart your computer using the cloned hard drive after that. Verify whether the inaccessible boot device after clone error has been resolved.
