What to do if the BIOS does not recognize the hard drive

What to do if the BIOS does not recognize the hard drive:

In the first case, the most likely data cable is not plugged in or there is a problem with the data cable. Or the power supply problem, the hard drive is supplied directly from the power supply interface to obtain power.

The white is the traditional IDE hard drive and the power supply interface of the optical drive, black is the power supply interface of SATA hard drive, ensure the power supply has sufficient output.

The second scenario is that the BIOS setup incorrectly causes the hard drive to issue (more rarely)

This type of problem is generally not the responsibility of users, because the current motherboard is used to automatically detect the type of hard disk and brand model features, so we usually do not make changes, but because some of the motherboard in the runtime may identify the type of hard drive errors in the situation, This happens in the same way that the system will not boot from the hard disk. In addition, the motherboard in the BIOS can also set the hard drive normal, LBA and large work mode, which must be based on the hard disk situation to set up, otherwise it is very likely that there will be other errors. The solution to this type of situation is not difficult, as long as the BIOS instructions for the motherboard and the hard disk itself are correct settings can be resolved.

The third scenario is a master boot program that fails to start the hard drive (the old hard drive, or a hard drive that originally had a system installed) that might have a similar problem. )

As we all know, the hard drive has a primary boot area, where the master bootstrapper is present, and if the main bootstrapper has a problem, then the system cannot be booted from the hard drive, which is a normal thing. This is not a very complicated thing to do, as long as you enter the FDISK/MBR command in DOS mode, which is largely due to the fact that the main boot of a hard disk is already included in the Fdisk command file, and now that Microsoft has thought about it, why not? From the current situation, the system is not able to properly boot the system there are many, but most of the common is mentioned in this article.

Computer does not recognize the hard drive solution:

First check the hard drive master and subordinate line settings are set wrong, the master-slave line set incorrectly will cause the system can not be correctly identified.

Test if the system can boot from the optical drive, if the optical drive does not boot the system, it is most likely the motherboard and power failure.

3 If the system still does not recognize the hard drive, you can use another computer to check the hard drive, to confirm that it is a hard drive failure, such as a hard drive failure, you should replace or repair the hard drive.
