Select the last correct configuration.

In fact, there are many reasons why it can't be turned on, such as no power and memory sticks, which need to be checked one by one, if there are no problems, you need to take it to the repair shop to check.

Look at the hard drive and install it on a different system.

Do you see if the hard drive cable is loose?

POST for disk boot test. This screen appears because the hard disk file was damaged due to the last improper shutdown, and the system is now detecting and repairing it.

1. The only thing you need to do is: wait patiently for it to finish, and it will automatically restart when it is done. If you can't get into the system after restarting, you need to reinstall the system.

2. If you need to enter the system in a hurry, you can also press the ESC key to skip the automatic repair and enter the system directly when the automatic repair screen appears, but the next boot will still need to be automatically repaired, and often skipping the automatic repair is easy to cause damage to the hard disk.

There are two reasons for this.

1. It may be a virus in the computer, resulting in system file corruption.

2. Hard disk failure.

2. If the above steps can be performed, then reinstall the system.

Reboot and select proper boot device or insert boot media in select boot should be due to the boot sequence being tampered with in the CMOS, which becomes a disc boot, and it cannot be automatically changed back to hard disk boot when the disc drive is not available.

Try if you can use other hotkeys to enter the BIOS, such as F2, if you can get in, you can manually modify the boot order, if you can't get in, it will be very troublesome, it is very likely that the motherboard has been invaded by a virus.

Of course, if you don't rule out the fault caused by other channels, you can try to change the optical drive.

Another: There is a problem with the boot part of your system, which means: reboot, then select the boot disk, or insert the bootable disk into the boot device of your choice.

Check whether the hard disk boot is set in CMOS, if it is, it is likely that there is a problem with the hard disk, check it after booting with the CD.

There are two main categories of BIOS: Award BIOS and AMI BIOS

1. Award BIOS settings the hard disk to boot.

After entering the BIOS, use the arrow keys to select Advance BIOS Features, then press Enter to enter the menu, use the arrow keys to select First Boot Device, click Enter to enter, use the arrow keys to select HDD-0, and then press F10 to save and exit. The boot mode was changed to hard disk boot. Everything!

2. AMI BIOS settings the hard disk to boot.

Go to BIOS, use the arrow keys to select Boot, select a Boot Device Priority, select 1st Boot Device in the submenu, and change this item to the corresponding hard disk.

The above is the introduction of the solution to reboot and select proper boot device when booting up, I hope it will help you!
