What happens when the computer turns on like this? How to deal with it?

Fault cause: ntldr is missing is generally caused by netizens mistakenly deleting ntldr files, and the current Trojans and viruses have not seen the behavior of deleting ntldr. So what should we do when we encounter ntldr is missing, here we need to use the installation disc of the operating system, see the following figure.

1. ntldr is missing when you upgrade from win9x to winxp.

ntldr is missing。

Of course, the following requirements must be met for this to occur:

a) The system boot partition is FAT32 file system.

b) The computer was started using the int-13 interrupt extension start. Generally, today's mainstream computers use this method.

c) Because at the time of clone, the burned system is stored in the value of the FAT32 BIOS Parameter Block (BPD) and the physical drive.

Shows the workaround for ntldr is missing.

First of all, enter the BIOS settings to boot from the disc, then insert the disc to reboot, after the "Welcome to the installer" interface appears, we select "To repair Windows XP installation using the recovery console, press R".

After entering the system fault recovery console, go to drive C, 3

Then enter "copy x:i386ntldr c:":" (x represents the drive letter) to copy the NTLDR in the CD to the root directory of the system disk, 4

Then enter "exit" to exit the console, take out the disc and reboot, if the reboot is not ntldr is missing, then it means that the copy is successful.

end Notes:

If it is not the loss of NTLDR caused by the artificial deletion of NTLDR and the computer cannot be turned on, then it is recommended that netizens use antivirus software and Trojan killing tools to conduct a full scan to check whether the system is poisoned.

Selecting all options and not responding? What system does the landlord have?

Computer boot hard drive self-test:

1. Improper shutdown, such as directly pressing the power button to turn off, or directly pulling the power plug;

Second, caused by sudden power failure;

Third, the program is suddenly forcibly interrupted when running, or several large programs are run at the same time, so that the CPU runs at full load, it is easy to report the disk read and write error, which will cause the damage or loss of the system file directory, in such a situation, it will often prompt in the lower right corner of the screen "The file or directory is damaged and unreadable, please run the chkdsk tool";

Fourth, the physical bad sectors that appear after the natural aging of the disk;

If it is the fourth case, if the bad sectors of the disk are not serious, you can use the isolation bad sector method to reluctantly use it, but it will not take long, if it is more serious, quickly back up the data and replace the hard disk.

If it is the first or second case, get rid of the habit of incorrect shutdown and try to avoid sudden power failure.

Disk self-test, just wait, caused by abnormal shutdown.

The last shutdown was not normal, the next time you boot up Windows will automatically run chkdisk to check the file system error, wait patiently for it to be completed, no problem the next boot will not appear again.

This condition is caused by a malfunctioning hard drive or system damage.

The solution to the computer blue screen is software first and then hardware, and there are generally more software problems.

1. The last correct configuration: Before booting and starting the system without entering the chain blocking, we keep pressing the F8 key, select "Last correct configuration" and then press Enter.

2. Safe mode: If the "last correct configuration" does not solve the problem, press F8 when you boot up, enter the safe mode, use software such as 360 to repair the system files, and check for viruses.

3. If it can't be repaired, we can enter the safe mode for system restoration.

4. None of the above methods work, and it is recommended to do the following:

Desktop host: 1) Power off, open the chassis, plug in and unplug the memory, wipe the gold finger part with an eraser, and plug it back in (don't reverse it).

2) Plug and unplug the graphics card, wipe the gold finger part with an eraser, and re-insert it tightly (the buckle should be buckled).

3) Unplug the power cord, cut off the button cell battery of the motherboard, wait for three minutes, and then reinstall the motherboard.

Laptop:

Unplug the power cord, remove the battery, open the back cover of the memory, plug in and unplug the memory, wipe the gold finger part with an eraser, and replug it in (don't do it the other way around).

Unplug the power cord, remove the battery, and press and hold the power button for 30 seconds without letting go.

If the fault persists, the system can only be reinstalled.

This is a system failure, the fundamental solution is to try the heavy mass mountain liquid touch system in the collapse, there is no other better way, satisfied with mine, this is the motivation for me to answer the question, thank you.

1. The computer battery is out of power, and it will return to normal after replacement. Or press F5 Enter and then press F10 Enter to try.

2. Enter the boot item in advanced mode, and select the "first" and "secend" items in order as hard disk and optical drive.

3. There may be some differences in the methods of different BIOS settings. Press F10 to press enter.

4. If the computer hard disk is faulty, plug and unplug the hard disk in the host, or replace the data cable, and then the hard disk will hang.

Press the Esc key, select Yes, and press Enter.

Reboot, f8 selects the last correct configuration. If it still doesn't work, you have to reinstall the system. Back up your data first.

This is the blue screen of the computer, and here's how to fix it:

1. Try the recommended to use the last correct configuration to restore, or enter the safe mode to uninstall the recently installed software.

2. If it doesn't work, you can only try to restore the system or reinstall the system.

There is a lot of garbage in the computer, the system performance is not strong, and there may be some software that is not compatible with the system, mine is to go to the maintenance office to find someone to optimize the system, which is cheaper than the heavy installation system, and the data will not be lost.

The blue screen is over, it is recommended to 1 restart 2 hit him 3 upgrade the system to kill and kill 4 buy a new computer.

Blue screen, installed some incompatible software, or has a virus, redo the system.
