The computer cannot start up. The English prompt is reboot and select proper boot device or insert boot media in selected boot.

When we start the computer, when it fails to start up, no matter what key you press is useless, it is the same prompt, as shown below:

Reboot and select proper boot device or insert boot media in selected boot device and press a key

Select an appropriate start device, or insert the start media in the selected start device, press the next key

Solution:

Unplug the USB flash drive from your computer and check whether your optical drive has a disk. If yes, restart the drive !!


Your computer may not be able to detect the hard disk (symptoms of the hard disk are not detected: Hard Disk information is not displayed in the IDE detection at startup) in this way, the system displays "reboot and select proper boot device or insert boot media in selected boot device and press a key"


The system can be accessed after the hard disk is detected.

Causes of failure in hard disk Detection:


1) if the motherboard BIOS is not powered, you cannot remember the hard disk information. If your system date is incorrect, this may be the reason.


Solution: Replace the BIOS battery and re-enter the hard disk for BIOS detection.


2) The ide quality is poor or cannot be properly inserted.


Solution: change the idea line or insert the idea line in another IDE slot on the motherboard. Do not connect the hard drive line to other ide devices, such as a optical drive, and separate the two idewires, correctly set the Master/Slave disk.


3) hard disk failure, which may need to be replaced.


4) if your computer can detect the hard disk and cannot enter the system, reformat the hard disk and reinstall the system.

Solution:

1. Go to BIOS settings, view the Startup Device List, and check whether the settings are correct. The options are HDD-disk, CDROM, and other device;

2. If the boot device is correct, your hard disk Boot Record is incorrect and you need to reinstall the system.

If the CDROM is in the front of the boot device, check whether there is a CD in the optical drive and it is not the boot disk.

Your prompt about failure in hard disk detection is in English.

The following problems may occur:

Causes of failure in hard disk Detection:

1) No power on the motherboard BIOS-replacing the BIOS battery

2) The ide cannot be firmly inserted.

3) motherboard driver damaged --- reinstall the motherboard driver

4) The boot sequence is changed to the boot sequence of the disc, but the optical drive does not have the relevant disk-you need to change the hard disk boot back.

5) The ntldr boot file is lost and repaired with the system disk.

6) Try to reinstall the system or change the hard disk.


Ntldr is an important boot file when Windows XP is started. The above prompt indicates that the file has been lost on your computer, you can directly copy one of the C disks from other systems of the same version or extract one from the Windows XP installation disc and store it in your c disk. If you are in trouble, installing Windows XP can also solve the problem.

Take 2000 as an Example

1. Start the computer with the installation disk of Windows 2000 and enter the installation interface of windows;

2. The page prompts "to fix Windows installation, press R" and press R to continue;

3. The page prompts the "use the fault recovery console to repair Windows installation" option, and press the C key to continue;

4. The error recovery console prompts "C: \ WINNT. Which Windows 2000 installation do you want to log on )?", Enter "1" here, and then press Enter;

5. Enter the administrator password and press Enter;

6. Type copy F: \ simpchin \

Windows2000 \ Server \ i386 \ ntldr C :\, press enter (Note: I use a three-in-one Windows 2000 CD, if it is another installation disk, you can use the search command to find the location of the ntldr file, which is generally in the i386 directory. "F:" is the drive letter of my CD );

7. Type copy F: \ simpchin \

Windows2000 \ Server \ i386 \ ntldr C :\, press Enter. The system prompts you to overwrite the file, Type Y, and press Enter.

Restart the computer

Take XP as an example: 1. Start the computer in any other way.

2. Run the Dir ntldr/s command to find this file from the backup file. The path is long. Copy it to the C root directory.

3. The key is to write data to the hard disk. If you cannot copy data, you must run the debug ntldr command. Execute the W command to write data in the command line, and exit the Q command. In this way, the data can be written to the hard disk.

4. Restart. How is it? The image I am waiting for is coming back immediately. Is it a little tearful. Ha, don't thank me. It's the same thing that Tianya has fallen into person, but I am unlucky before you, find a solution to it. Don't forget if you have any good stuff to share with me

Ii. Fixed Windows XP startup system

1. Start the computer with a CD drive in BIOS settings

2. Place the Windows XP disc and start the computer in the drive.

3. after the CD is automatically executed until it is stopped, there will be three options. Press [R] to select the computer to repair, and you will be asked which system to enter. Please select the Windows XP code, enter the administrator password (the same as the administrator password entered during installation). If you do not have a password, press Enter.

4. Type fixboot in C: \ Windows> and press [y] to confirm

5. In C: \ Windows>, type the CD \

6. Type attrib-H ntldr under c: \>

7. Type attrib-s ntldr under C: \>

8. Type attrib-r ntldr under C: \>

9. Type attrib-H ntdetect. com under c: \>

10. Type attrib-s ntdetect. com under c: \>

11. Type attrib-r ntdetect. com under c: \>.

12. Type copy X: \ i386 \ ntldr c: \ Note: X: The same as the code of the drive.

13. Under c :\>, type copy X: \ i386 \ ntdetect. com c :\

14. After the operation is complete, retrieve the Win XP disc and type [exit] to restart the computer.

15. Enable the computer after selecting and using the hard disk in BIOS.

16. if the Chinese version of Windows XP is garbled during startup, you can enter the bootfont in the i386 directory of Windows XP. copy bin to the root directory of drive C. bin can be deleted from the root directory of drive C.


Recently, a problem has occurred on a friend's computer. The system prompts "reboot and select proper boot device or insert boot media in selected boot device and press a key" when starting the system. I believe many people have encountered this problem. The system disk is actually wiped in. Even if you set it to boot from the disc in Bois, this prompt is displayed.


The following describes how to solve this problem.


1. Remove the hard disk and take it to another computer for partitioning. After dividing it, insert it back to the computer. At this time, set the optical drive to start.


2. Insert the system disk. If the installation screen of the system disk is displayed, a micro-system is installed on the system disk. You can start the system on the system disk and then click ghost to install the system disk to drive C, generally, you can use this method to start the CD system, which means that your hard disk and other hardware are okay.


3. after the system is installed, after you take out the disc, you will be prompted to boot it. You only need to enter Bois and set the first boot to hard disk boot. Do not set it to disc boot. The system can be started. Generally, this problem is caused by bad sectors on the hard disk.


"Reboot and select proper boot device or insert boot media in selected boot device and press a key" means to restart and select the correct boot device or insert the boot media to choose start.

The system can be accessed after the hard disk is detected.

Method 1:


Causes of failure in hard disk Detection:

A: The motherboard BIOS is not powered, or the BIOS settings are incorrect. You cannot remember the hard disk information. If your system date is incorrect, this is probably the reason.

Solution: Replace the BIOS battery and re-enter the hard disk for BIOS detection. Open the chassis, remove the bright battery on the motherboard, and try again in a few minutes. Unplug the power cord of the chassis first.

B: The quality of the IDE/SATA cables is poor or cannot be properly inserted.

Solution: Change the IDE/SATA line or insert the IDE/SATA line into another IDE/SATA slot on the motherboard. Do not connect the hard drive line with other ide devices, such as the optical drive, separate Two idex connections and correctly set the Master/Slave disk.

C: hard disk failure, which may need to be replaced.

D: The Boot Sector of the hard disk is faulty.

You can check in the BIOS to see if the hard disk can be found in the BIOS. If no hard disk is found in the bios, the hard disk may be broken. If you can find the hard disk in the bios, set the optical drive to start, put the system disk in the optical drive, and reinstall the system.


The last method is the original method used to solve the problem: plug the motherboard and the hard disk multiple times, and try to plug the power cord several times, the system is started successfully!


Method 2:


Press "F8", Press enter, press enter, and enter "safe mode ",

Find: "Last correct Settings", click Next, and try!

2. Alternatively, find the "normal startup" Mode in "security mode", click Next, and try again.


Method 3:


After the computer is turned on, (the computer can be operated only after the "brand" is obtained )!

Press the "+" on the rightmost keyboard ("+" on the keypad) "one-click Rescue" shortcut key

(For laptops, press F2 or F11 ),

Wait and press "one-click deep restoration" or "one-click Ghost ",

Wait for the system to "save and copy" all disk files. Note: After the disk is restored, do not shut down or restart the computer. You should "Enter the main platform" immediately ",


That is, "desktop". Otherwise, "Success is all done" and "restoration is invalid "! The computer immediately returns to the "factory status "!

Start downloading "360 security guard" and "360 anti-virus dual-engine version ",

Start scanning viruses and Trojans in full,

Fix computer vulnerabilities! "Factory status": it is the status when you just bought it,

All the software is there, so you don't have to "reload the system". It's a lot easier to install than to worry about it!

Or, take out the "Instruction" for buying a computer and compare it with "restoring the system "!
