An inaccessible Boot Device is a BSOD error that can be caused by a number of things, including faulty system files, a bad hard drive, and so on. You can fix it by adopting a few options for resolving the Inaccessible Boot Device issue in Windows 10.
The Inaccessible Boot Device error is a blue screen of death (BSOD) that appears when Windows starts up. The error code 0x0000007b is displayed. During startup, Windows lost access to the system partition, as indicated by the error message. This issue can be caused by a variety of factors, including corrupt system files, incompatible device drivers, malware attacks, malfunctioning hard drives, and so on. If this issue occurs after copying, you will be unable to boot Windows normally from the cloned disc and will also be unable to access the saved data. We’ve discussed various troubleshooting options for the inaccessible boot device problem and hard drive recovery.
Methods to Restore Access to an Inaccessible Boot Device after a Clone
To fix the Inaccessible Boot Device problem in Windows 10, use the methods listed below.
Method 1: Change the Boot Sequence
When you choose the wrong drive to boot from, you may get the Inaccessible Boot Device error. If your computer has more than one hard drive, go to the BIOS configuration and change the boot Sequence to begin with the cloned hard disc. The steps are as follows:
- Restart your Laptop/PC.
- To enter BIOS Setup, hit any of these keys (F2, F8, F12, or Del) repeatedly when the startup screen appears.
- Choose Boot and select the cloned hard disc as the first boot option.
- Additionally, hit F10 to save and leave the BIOS.
- Now restart the computer to verify if it boots up normally.
Method 2: Double-check to see whether you’ve cloned the wrong disk.
Another cause of the Windows 10 Inaccessible Boot Device problem could be that you copied the wrong drive. As a result, you’ll need to re-clone the hard drive. Follow the procedures below to see if you’ve cloned the wrong drive:
- The cloned hard drive must first be installed on your computer.
- Then, from the original drive, restart your computer.
- Open the copied drive in Windows File Explorer.
- Look for the “Windows” folder on the cloned drive as well:
a). If you see one, it means your hard drive has an operating system installed. As a result, the Inaccessible Boot Device problem is caused by something else.
b). If you couldn’t, it’s possible that you cloned the wrong drive. As a result, you’ll have to re-clone the hard drive.
Method 3: Use the CHKDSK utility to check for errors.
When a hard drive contains bad sectors or is compromised with malware, problems such as the Inaccessible Boot Device error can occur. You can use the CHKDSK utility to resolve this.
Note: The CHKDSK tool stops Windows from accessing and storing information from bad sectors. You may lose all data saved in bad sectors if you execute the CHKDSK tool. As a result, build a data backup before proceeding.
To launch the CHKDSK program on Windows 10, follow the steps below:
- In the Search Box, type cmd and choose Run as administrator.
- Then, in the text area, type the command “chkdsk f: /f” and press the Enter key.
- It’s possible that the procedure will take some time to complete.
- Close the window and restart your computer after you’re finished. After that, see if it fixed the Inaccessible Boot Device problem.
Method 4: Run a scan with System File Checker (SFC).
System File Checker is a built-in Windows application that checks for corruption of system files. It analyses all protected system files for corruption and replaces them with the right versions. Follow the steps below to do an SFC scan:
- Select Run as administrator from the Command Prompt menu.
- Type SFC/scannow into the text area and hit the Enter key.
- Close the window and restart your computer to see whether the Inaccessible Boot Device error has been resolved.
Method 5: Update Windows 10 Device Drivers
Defective, inappropriate, old, or faulty device drivers are one of the most common causes of the Inaccessible Boot Device issue in Windows 10. As a result, you can update your drivers by following the procedures below:
- Open Device Manager and choose the device category for which the driver needs to be updated.
- Right-click the driver you want to upgrade and select Update Driver.
- Additionally, select Search automatically for drivers. Windows will begin looking for updated drivers.
- If Windows is unable to locate any, use the Windows Update option to search for updated drivers. It will show you all of the updates that are available.
- Finally, click ‘Install Now’ to upgrade your Windows 10 system with the newest updates and driver software.
