It s been like this since the computer restarts.,It s useless to restart.,What to do?,Solve 20.

This boot can't go in is generally because the memory is loose.,No problem with the connection.,Remove it and wipe it.,Reinstall.,It should be OK.。

In order to avoid the loss of data, it is recommended to back up your data in advance.

In the actual work environment, there are several main reasons for this phenomenon:

1) Hard disk failure (such as: hard disk bad sector, hard disk circuit failure, etc.).

2) The boot information of the hard disk MBR is incorrect (note: relative to the host, the hard disk does not have any system installed).

3) The boot file or configuration file of the operating system is incorrect.

4) The current host has multiple hard disks, but the boot disk cannot be effectively identified due to the incorrect boot sequence setting.

5) There is a floppy disk in the current floppy drive.

For this problem, it can be traced back to the last time when it was used normally, whether tools such as changing the boot menu and partition adjustment were used. If there is, you can basically rule out the possibility caused by hardware, and you only need to operate according to the repair and restoration methods provided by the tool.

1. Check whether the hard disk under the BIOS is recognized.

If you don't recognize the hard drive model, you can check whether the hard drive data cable and power cable are loose under the guidance of an experienced person, and try to reconnect the test if necessary. In the case that it is still not recognized after operation, it is recommended to contact the official after-sales service for testing.

2. Choose the right boot device.

The first boot item of the BIOS is set to boot on the hard disk with a boot disk.

3. Use the System Recovery Console to repair.

Boot to WinRE (Windows Recovery Environment), which can be understood as recovery mode.

You can press and hold the power on button until the machine is powered off, then turn it on again, and then power off again, repeat 3-5 times until you enter the recovery mode as shown below.

From the Select options screen, tap or click Troubleshoot.

Tap or click Advanced options, and then tap or click Automatic repair.

4. Restore factory state test.

5. Contact the official after-sales inspection.

If the above operations still do not solve or improve the problem, we recommend that you bring the main unit and purchase invoice and send it to the nearest Lenovo service outlet for further testing.

In this case, I have also encountered a power outage, open the chassis and change the SATA cable of the hard disk on the motherboard, but if the replacement fault is still possible, the hard disk is not normal, at this time, it is best to ask a professional to check it.

Look at what you sent**,This is a problem with your hard drive.,Change it!
