My computer reinstalled the system, and the following prompt appeared at boot MISSING OPERATIEN SYST

The best way to do this is to repartition it. Could it be that your primary partition boot is faulty, or it is not activated, do you have more than 2 primary partitions?

There is no problem with the optical drive,I just encountered such a problem,I said my problem,My 80 disk I was poisoned by the computer,Then I installed the system I didn't expect my xp system disk to be broken,I then used the 98 boot disk to install,Because I can't understand English accidentally deleted the disk partition,So I bought an XP disk to install because I began to use the 98 disk to delete the partition,So the system with XP to partition,I divided the area to install the XP system boot on the missing operating system,I didn't know why at the time,So I used the partition tool to delete the C drive in the system that was packed with XP, and the result was even more depressed!

After booting, not only did there not appear error loading operating system, after many times of installation I finally knew that it was a partition problem, because I have important files in the partition so I can't fully divide, because my computer main partition has more than 50g, can not be divided into logical partitions (hint - because there are important files) I can only divide the main partition into 3 and then install the system on the main partition The result is ok,

I'm sure to tell you, it's not a hardware issue.

It's because you don't have a good partition, for example, as mentioned above, you don't activate the main partition, only after activation, the computer can recognize some partitions as system disks. The boot partition and files will be created.

Therefore. If you don't have important files, it is recommended that you repartition and reinstall the system with a tool disk.

If you have important files, you can simply remove the hard drive, copy the files on another machine, and reinstall them!

In general, there will be no problems with the hardware.

It is recommended to change the system disk and install all the drivers.

Try to install it on a new system disk, if it doesn't work, it may be a motherboard failure.

Hello, according to your prompt, your computer system files are missing, and this can be solved by reinstalling the computer system.

This is due to the fact that the operating system cannot be loaded, it may be that the hard disk hardware is damaged, or it may be the operating system software is damaged, if it is only software corruption, reinstalling the system is fine.

This is a system failure, you can fix the boot first, if it doesn't work then you can only reinstall the system.

This English means system loss.

Some key files of the system are lost, resulting in system corruption, and basically have to be reinstalled.
