An inaccessible boot device error is an issue that can occur on Windows computers when the computer fails to recognize and use the device it is set to boot from. This can be a very frustrating issue as it can cause your computer to not boot or even crash. The most common causes of this issue are misconfigured BIOS settings, corrupt system files, a corrupted or damaged hard drive, virus or malware infection, and a faulty device driver.
In order to fix this issue, you will need to access your computer’s BIOS settings. To do this, restart your computer and press the key that is designated for entering the BIOS. The exact key may vary depending on your computer’s make, model, and BIOS setup, but it is usually F2, Del, or Esc among other keys.
Once you are in the BIOS settings, you will need to check the settings for the boot order. Here you should ensure that the device you are trying to boot from is listed first. After saving the BIOS settings, restart your computer and try to boot again. If the issue persists, go back into the BIOS settings to double-check that the boot order is correct and save the settings again before restarting your computer.
If the issue still persists after following this step, then it may indicate that the issue is caused by a corrupt system file, virus or malware infection, or damaged and faulty device drivers. To fix these issues, you will need to run a full system scan with your antivirus or anti-malware software to detect any malicious files or programs. If any malware is detected, it is important to remove them. You should also update the device drivers on your computer to ensure that they are not causing the issue.
In some cases, the issue may be caused by a damaged or corrupted hard drive or other storage media. If this is the case, you might try to use a data recovery tool to recover the lost or corrupted data. However, if the data cannot be recovered, then you may have to replace the hard drive to fix the issue.
Finally, if none of the above methods work, then you may need to reinstall your operating system. Before doing so, it is important to back up all important data as a reinstall will delete any existing data on your computer.
Overall, an inaccessible boot device error can be a frustrating issue to deal with as it can cause your computer to not boot or even crash. In order to fix this issue, you will need to access your computer’s BIOS settings, check the boot order, and ensure that the device you are trying to boot from is listed first. Additionally, you will need to run a full system scan to detect any malicious files or programs, update the device drivers on your computer, and possibly replace the hard drive or reinstall the OS.
