All of a sudden, the computer is like this! Who knows how

Set to boot from the hard disk, if it doesn't work, reinstall. Please don't ask, everything that should be said has been said, and typing is tired.

Just follow the methods and steps inside, and it's very detailed. (More powerful, there are a lot of tools in PE, including formatting, partitioning, backup, boot recovery, etc.) Reminder: Before restarting after installing the system, please pull out the USB flash drive.

3. Disc installation method: Keep pressing the del key when booting up, enter the BIOS, set it to start from the optical drive, exit after saving, put in the disc and restart the machine, select the installation system option after entering the installation screen, after installation, before restarting, use the previously mentioned method to change the boot mode to start from the hard disk, and restart the machine.

Special note: If there is an accident in the installation process or the installation of individual machines is not ideal or ideal, or some hard disks have reserved or hidden partitions (left by the system with win7 or better version, usually 100-hundreds of megabytes), please enter the PE system to format them and repartition them before installation.

I just didn't find the hard disk, I can't start the system, it is estimated that the power cord or data cable of the hard disk is loose, it is recommended to check the power cord of the hard disk and the data cable of the hard disk, and try to plug the cable back in and out again after the power is off.

If the system is installed in an SSD drive, plug and unplug the SSD drive.

If none of the above solves the problem, check whether the motherboard BIOS settings are set to network card boot, and if so, restore the default settings of the BIOS directly.

If it hasn't been resolved, it may be that your system boot file is corrupted and you need to repair the boot file or reinstall the system.

This is a problem with the disks, please fix it (fix it for each disk or just fix c).

Built-in disk repair method:

The specific steps are as follows: select the drive letter in my computer, right-click to select the properties, select "Tools Start Checking" in the pop-up drive properties window, and select "Automatically repair file system errors" and "Scan and recover bad sectors", and then click Start, the scanning time will vary depending on the disk capacity and scanning options (after doing it according to the above method, a box will pop up, the point is, repair after automatic shutdown at boot, win7 select the disk check button according to the plan).

Bad sectors on the hard drive will lead to corruption or loss of computer system files, computer failure to boot or freeze. Hard disk bad sectors can be repaired using NDD Disk Utility or Scandisk.

If the fault persists, please restore the system or reinstall it (it is still not possible to format the hard disk and repartition and reinstall it, if it doesn't work, you will have to replace the hard disk, or overhaul it).
