The nec laptop boots up with INvalid SYSTEM DISK 20

The prompt is "The system disk does not exist"!

That is: there is no system that can be used to boot!

Causes: 1The operating system is broken and the boot is not recognized: just reinstall the system!

2.Hard drive lost connection: Check the data and power cables of the hard drive and motherboard!

Instructions: 1In the first case, it is also possible that "the active partition of the hard disk has been changed, the system is good, but the partition it is in is not the active partition", you have to use partition management software (partitionmanager, etc.) to activate the partition where it is located!

In this case, ghost is useless to reinstall the system unless it is installed on the active partition.

2.Boot into the BIOS to see if the hard disk can be detected, and you can judge whether it is the first or second case.

3.If you have dual hard disks, you also need to see if your boot sequence is correct, and you need to boot from a system disk.

1.The startup file does not exist.

2.The system partition is not activated.

3.System Partitioning...

What exactly it is, let's find someone to see.

If you can't find the operating system on the hard disk, it may be that the key files of the system are corrupted, or it may be that there are bad sectors on the hard disk. There are many reasons, falls, viruses, misoperation, and the hard drive is dead. First find out if the hard disk hardware is damaged, and find a tool to check it.

1: Start XP with WinXP PE

2: Copy a normal system program file and save it as a "C: Windows System32 file."

3: Copy a normal system dll component program file and save it as a "c: windows system32 file."

4: After following the steps 1-3 above, restart the computer once and everything is repaired.

5: You can log in normally after restarting, but there are still remnants in the system.

6: After the system is repaired, use antivirus software to check and kill viruses.

If you are troublesome, reinstall the system!

Use the fn key and the power button to turn on,See if you can self-check,Or can't display is to connect an external monitor to see if it can be lit up,It is estimated that it can be lit up is a matter of the back screen line,If you can't light up, find other problems。

The display cable is broken.,It's the central axis.,Is there a Ding Dong province to turn on?。

Reboot press F2

Press F9 again to restore the factory settings.

If you don't set the priority boot in time, the hard disk can also be started, there are only 2 possibilities in this case, the hard disk data cable is damaged or not connected, or the hard disk power cable is not connected! Unpack and check quickly!! Mu sedan car!

Try it with the system disk.

This is a typical hard disk partition error caused by the fault, it is recommended that you restore the CMOS to the initial settings, turn off the motherboard CMOS virus firewall, and then use the system tool disk to re-partition the hard disk format (if there is important data, first connect to other computers for backup) should be OK, good luck!

It is recommended to use the PM program in the PE tool disk to delete the C drive partition, rebuild the C drive partition, and activate the C drive partition.

Then install the system using a one-click CD-ROM type, or install the system in the normal way.

C disk boot needs to be rewritten,The easiest way,You go to find an installation disc (not ghost),Install it,Rewrite the boot on it。

Are the boot options in your BIOS not set up?

Check it out, what is the boot sequence 1st. cd rom? disk? floppy disk? usd ? network?

Next, look up your disks

It should be a hard disk problem, maybe the hard disk is broken, or the computer can't be connected to the hard disk, probably the interface is aging, etc., it is recommended to disassemble it to see how the interface of the hard disk is, or go directly to the repair shop.

It may be that the hard disk interface is loose, I have encountered such a situation, and I tried it again with a different interface, okay!

That's because your own hardware is malfunctioning! I can't start my computer properly.

When you boot up, it will prompt what kind of hardware failure it is, in English, you send it to see, just press F2 enter BIOS setup on the above sentence or two.

The BIOS displays information. Normal. It is estimated that you adjusted your BIOS more when installing the system. You can set the BIOS to block out the boot display.

Obviously, your system can't start normally.,Reinstall the system.,The prompt message is to put you into the system disk.,Press F2 to enter the installation interface.。

After entering the BIOS, turn off the floppy drive, and select the hard disk as the first boot item.

Locate First Boot Device -- First Boot Item -- Second Boot Device -- Second Boot Item ---Third Boot Item) under Advanced BIOS Features

What you do: Do nothing. Wait a while and the machine will enter the system on its own. In other words, this is the way the computer must go before it enters the system. ok！！

Why do you want to press it? If you don't press it, won't you go straight to the system?

Whether it is slow to boot or boot to detect the disk.
