Methods to Fix Inaccessible Boot Device after Clone

Proceed with the below-given methods to Fix the Inaccessible Boot Device error in Windows 10.

Method 1: Change the Boot Order

The Inaccessible Boot Device error may occur if you set the wrong drive to boot from. If you have more than one hard drive on your computer, then go to the BIOS setup and change the boot order to start from the cloned hard drive. Here are the steps:

• Restart your computer.
• When the startup screen appears, press any of these keys (F2, F8, F12, or Del) continuously to enter BIOS Setup.
• Select Boot and choose the cloned hard drive as the first boot option.
• Further, press the F10 key to save and exit the BIOS.
• Now, restart the PC and see if it starts without any issue.

Method 2: Check if you have Cloned the Wrong Disk

Another reason behind the Windows 10 Inaccessible Boot Device error is that you might have cloned the wrong disk. Thus, you have to re-clone the hard drive. To check if you have cloned the wrong disk, follow the below steps:

• Firstly, you have to install the cloned hard drive on your computer.
• Then, restart your computer from the original disk.
• Open Windows File Explorer and the cloned drive.
• Further, search for the “Windows” folder on the cloned drive:

1. If you get one, it signifies that you have an operating system installed on the drive. Hence, something else is causing the Inaccessible Boot Device error.
2. If you couldn’t, then it means you have cloned the wrong disk. Thus, you need to re-clone the hard drive.

Method 3: Run the CHKDSK Utility

When the hard drive consists of bad sectors or is infected with the virus, it can result in issues, such as Inaccessible Boot Device error. To fix this, you can run the CHKDSK utility.

Note: The CHKDSK utility prevents Windows from reading and storing data stored in the bad sectors. On running the CHKDSK utility, you may lose all the data stored in the bad sectors. Thus, make sure to create data backup before proceeding.

Follow the below-given steps to run the CHKDSK utility on Windows 10:

• Type cmd in the Search Box and select Run as administrator.
• Then, type in the command “chkdsk f: /f” in the text field and press the Enter key.
• The process may take some time to complete.
• Once done, close the window and reboot your system. Then, check if it helped you fix the Inaccessible Boot Device error.

Method 4: Run System File Checker (SFC) Scan

System File Checker is an in-built Windows utility that checks for system file corruption. It scans all protected system files and replaces the corrupted files with the correct ones. To run an SFC scan, follow the below-given steps:

• Open Command Prompt and select Run as administrator.
• In the text field, type SFC/scannow and press the Enter key.
• Once finished, close the window and restart your PC to check if the Inaccessible Boot Device error is fixed.

Method 5: Update Device Drivers in Windows 10
