Lenovo win 10 cannot be turned on after automatic repair.

1. Enter the computer BIOS, switch to the system configuration interface, and change Legacy Support to Enabled, that is, start the traditional mode. Then adjust the USB flash drive startup to the first item in the following traditional startup order, save the changes, and then restart. (Different brands of computers enter the BIOS in different ways: Lenovo computers press F 12 or F2, and HP computers press F 10. )

2. After starting in the traditional mode, enter CMD in the search to open the command prompt window, which is the black window of CMD.

3. Enter "bcdedit /set recoveryenabled NO" in the command prompt window, and then click the Enter key on the keyboard to turn off the automatic repair function of the operating system.

4. Enter the computer BIOS, switch to the system configuration interface, and change Legacy Support to Disabled, that is, close the traditional mode. Restart in UEFI mode. At this time, you will enter the system repair error prompt interface (the picture shows the network diagram, and the error file prompted by your friend's computer is C: \ Windows \ System32 \ ntkemgr.sys).

5. Record the error file path, enter the BIOS, switch to the legacy startup mode, plug in the WinPE startup USB flash drive, find the corresponding error file in the USB flash drive WinPE system, and then transfer it to other disks for backup. (Note: Some files cannot be deleted under the win 10 system environment. You need to enter the USB flash drive WinPE system to delete them. )

6. Restart the computer, enter the BIOS, switch to UEFI startup mode, save the settings, and then restart the computer.
