What should I do if the computer cannot boot when ntldr is missing appears?

Solution: 1. Check whether there are external devices connected to the computer, such as USB flash drives, CDs, etc. If so, please disconnect it and restart the computer; 2. Check the boot sequence setting of the hard drive. Enter the BIOS setup interface, find the boot options, make sure the hard drive is set as the first boot device, etc.

When the "NTLDR is missing" error message appears on the computer, it may be due to the following reasons:

1. NTLDR file is missing or corrupted.

2. The hard drive's boot sequence is set incorrectly.

3. The system boot file has been illegally modified.

Here are some possible solutions:

1. Check if there are any external devices connected to the computer, such as USB flash drives, optical discs, etc. If so, disconnect it and restart your computer.

2. Check the hard drive's boot order settings. Enter the BIOS setup interface (usually press the power button followed by the DEL or F2 key), find the boot options, and make sure the hard drive is set as the first boot device.

3. If the NTLDR file is indeed missing or damaged, you can try to repair it by the following methods:

• Use a Windows installation CD or Start the computer from the system recovery disk, select the Repair your computer option, and follow the system prompts.

• If you do not have an installation CD or system recovery disk, you can try to copy the NTLDR file from another working computer to the root directory of the system disk of the problematic computer.

1. If none of the above methods solve the problem, you may need to consider reinstalling the operating system. Before reinstalling, be sure to back up important data.

Note: Before performing any repair operations, please ensure that you have sufficient computer knowledge and understand the risks that may result in data loss. If you are not sure how to proceed, it is recommended to seek professional help.
