Causes of Hard Disk – (3F0) Error
• Incorrect BIOS Settings – There’re are various BIOS settings that are very crucial for the system to boot into an Operating System. For example when the Hard Disk is missing from the boot devices or it is not set as the primary device.
Another setting is about the partition style the computer expects on the Hard Disk. There’re two partitioning styles i.e MBR and GPT. When a computer expects MBR and it finds GPT, it won’t be able to read the data on the partition which is the same for the other way round.
• Damaged Boot Loader – A Boot Loader is a program that’s responsible for identifying any Operating Systems on the Hard Disk as well as allow booting into the available Operating Systems. Any slightest misconfiguration in the program can prevent the computer from booting into an Operating System.
• Corrupt Partition – Any partition on the Hard Disk can be corrupt for a number of reasons for example misconfiguration from the user, or as an effect from another program for example malware.
• Loose Hard Disk connection – If the Hard Disk is not connected well to the motherboard, the computer won’t be able to detect it and find an Operating System. This results in the BootDevice Not Found error.
• Faulty Hard Disk – Sometimes the Hard Disk lifetime is just over. If the Hard Disk is faulty it won’t be able to be detected by the computer thus the error.
Solutions 1: Fix BIOS Settings
The most straightforward way to fix this is to reset the BIOS settings to their default state with the following steps:
1. Boot up the computer and press the key that allows you to open the BIOS settings. For most HP models it’s the F10 key but different manufacturers set different keys, for example, Esc, F2, F9, F12. That said, find the BIOS key for your specific computer model.
2. Look through the various sections to find the option for Reset to defaults. The label varies between different models. On some computers, it is Restore defaults/Factory reset or something similar. Select the option, confirm to load the defaults then exit after saving the settings. Reset BIOS Settings to default
3. If this doesn’t fix the error, try the next BIOS fixes.
Another fix for the BIOS Settings is to set the Hard Disk to the primary boot device.
1. Open the BIOS Settings as we did earlier in the first BIOS fix
2. Navigate to the section with Boot Options
3. Navigate to the section with the order of the boot devices and set the Hard Disk as the first device in the sequence. Change Boot Order to make Hard Disk first
4. Exit while saving the settings and check if the error is fixed.
One more fix for the BIOS Settings is to make the System be able to access data on the Hard Disk despite its partitioning style (MBR/GPT). BIOS Settings configure the computer to boot in either UEFI mode or Legacy mode. MBR partition style can be accessed if the computer boots from the Legacy mode whereas the GPT partition style can be accessed if the computer boots from UEFI mode. Some computers provide options for booting with both UEFI mode and Legacy mode while others provide only one option.
PRO TIP: If the issue is with your computer or a laptop/notebook you should try using Restoro Repair which can scan the repositories and replace corrupt and missing files. This works in most cases, where the issue is originated due to a system corruption. You can download Restoro by Clicking Here
1. Open the BIOS Settings as we did earlier in the first BIOS fix
2. Move to the boot settings tab and navigate the section with the Boot mode which has options like Legacy or UEFI. Change Boot Mode
3. Change this boot mode through the various options available while saving the settings and booting up again to check if the error is fixed.
If these BIOS Settings tweaks don’t solve the error, try the next solutions

Solution 4: Replace the Hard Disk
This should be the last option since it has the most negative effect in terms of the cost as well as the data loss. Before buying a new Hard Disk, you can try using this Hard Disk as an external drive and see if you can access it and if you can then you probably won’t have to throw it away.
