The computer problem is very serious, and the master solves it with gratitude 15

Launch Disk Genius, press the Alt key to activate the function menu, and select the "Tools Rebuild Partition Table" menu command. At this point, the program will appear "It is recommended to back up the partition table first" prompt, after clicking the "Continue" button, Disk Genius provides two ways to rebuild the partition table, namely "Automatic" and "Interactive". The automatic method retains every partition found when searching for partitions, which is suitable for most cases; The interactive mode prompts each partition discovered, and the user chooses whether to keep it or not.

Based on the system message, it is inferred that the DOS partition table is wrong. A computer's hard disk allows multiple partitions, but only one active partition with a boot flag of "80h". When the main boot record cannot find the flag or finds more than one flag, the invalid partition table prompt appears.

You can use programs such as KV300 to check whether the active partition flag (1be is 80h) and the end of partition flag of the hard disk partition record are missing, and if they are missing, you can use diskedit to correct them. If the fault persists, start the disk with the boot disk and then repartition it with the fdisk command.

Note: Repartitioning with the fdisk command will lose all the data on the hard drive, so you need to make a backup of your data before proceeding, and it is best to be guided by an experienced person.

It may be that the DOS partition table is wrong. You can take a look below.

There are multiple ways to solve this.

The screen displays: The hard disk allocation table is wrong.

That's a challenging question!

I've encountered this problem before, I installed a shadow system, and then protected the hard disk, and then restarted it and couldn't enter the system, and finally formatted all the disks of the hard disk and reinstalled it.

1.Did you format all your hard drives? Or only format the C drive, if the format C disk can't get in, I suggest formatting all the disks, in the installation of the system, that is, the data in the hard disk will be a pity.

2.And the way you install the system is right?

3.If it doesn't work, the hard disk is broken, and the hard disk is replaced.

4.If the processor, memory module, and other hardware are damaged, you should check them carefully.

Most of the time it is a hardware failure, take a look at the prompts, check the memory, graphics card, if it is a desktop, see if there are still those cards inserted, except for the graphics card, unplug them all, and try again.

Good luck!

Check the memory, unplug the memory and plug it in.
