A hard disk boot failure usually occurs when the machine is started. This failure may be caused by the system itself or by a virus. The fault caused by the virus can be solved by checking the antivirus, so the following analysis of the fault other than the virus for your reference:
This article refers to the address: http://
1, HDD controller failure (hard drive control failure)
This is a timeout error that occurs when the POST program issues a seek command to the drive and the drive does not complete the operation within the specified time. With this error, it is possible that your hard drive has been damaged.
2, C: drive failure (hard disk C drive failed)
RUN SETUP UTTLITY (run setting function)
Press to Resume (button restart)
This type of failure is generally caused by the type setting parameters of the hard disk not matching the parameters used during formatting. Since the setting parameters of the IDE hard disk are logical parameters, most of the cases are started by the floppy disk, and the C disk can be read and written normally, but it cannot be started.
3, Invalid Drive Specification (invalid drive letter)
If a partition or logical drive does not exist in the partition table, then the partition or logical drive does not exist for the operating system, so this problem is usually in the partition table. The easiest way to fix such a fault is to back up the partition table in advance. For example, Pctools9.0 and Kv3000 have this function.
4, Error Loading Operation System (adjust operating system error)
This type of failure is prompted when an error occurs in the read partition boot area (BOOT area). The reason may be that the partition starting physical address indicated by the partition table is incorrect. For example, due to misoperation, the starting sector number (in the third byte) of the partition table entry is changed from 1 to 0, so after the INT 13H fails to read the disc, the error is reported; the second is the track of the track where the partition boot sector is located. The flag and sector ID are corrupted, the specified sector cannot be found; the third is the drive read circuit failure.
5, the hard disk can not boot the system, if there is a floppy drive, it is booted by the A drive, showing: DRIVE NOT READY ERROR (device not ready)
Insert Boot Diskette in A: (insert boot disk to drive A)
Press any key when ready (press any key when you are ready)
This is because the hard disk boot system, it is necessary to read the hard disk 0 side 0 channel 1 sector through the BIOS INT 19H, looking for the main boot program and partition table. The reasons for the failure of the INT 19H to read the main boot sector are: first, the hard disk read circuit is faulty, causing the read operation to fail, which is a hardware failure; second, the 0-side 0-track format and the sector ID are logically or physically damaged, and cannot be found. To the specified sector; third, there is no error in reading the disc, but the read MBR tail is not "55AA", the system thinks that the MBR is incorrect, which is a soft fault.
6, Non-System Disk or Disk Error
Replace And Press any key when ready (non-system disk or disk error, press any key after re-changing)
After the boot program in the DOS BOOT area is executed, an error is found and this information is reported. The possible reasons are: the first sector address of the hard disk root directory area is out of bounds (after 540M), and the disk read error. Most of these faults are software faults. If the BPB table is damaged, the hard disk cannot be read and written normally after booting with a floppy disk. It can be repaired with NDD. If the BPB table is intact, only the simple SYS C: transfer system can boot.
7, NO ROM BASIC (without curing BASIC)
SYSTEM HALT (system shutdown)
This type of error often occurs on 486 and previous machines, and is a reminder of quite old machines. The role of the main boot program is to find an active partition (bootable partition) among the four entries in the partition table. If none of the four entries is the active partition, the system does not know where to boot the operating system, can only execute INT 188H, call the solidified BASIC program, if it does not solidify BASIC, it will cause a crash. So the easiest way to fix it is to use FDISK to set up an active partition on your hard drive.
8, showing "Starting Windows...", then crash
In general, this is because the executable file in CONFIG.SYS and AUTOEXC.BAT itself is corrupted, causing the system to crash when it executes this file. This fault is very simple, but because there is no fault information, the average person is prone to misjudgment. When this happens and you are sure that the system files are intact, you can remove the two files, or when the above information appears on the screen, quickly press the F8 key, then select single step to find the damaged file. .
9, Invalid Partition table (invalid partition table)
After finding the active partition, the main boot program will also determine whether the "partition boot flag" byte (first byte) of the remaining three entries is 0, that is, whether there is only a unique active partition, if one is not 0, the system will report an error and crash.
10, Invalid Media Type Reading Drive X (X drive media type is invalid)
Abort, Retry, Fail?
This message is prompted for an invalid BPB table in the DOS BOOT area. The BPB table is a bridge for converting the logical address used by DOS to read and write the hard disk into a physical address. If the BPB table is damaged, the operation of the DOS on the disk cannot be discussed.
11, HDC controller fail (hard disk controller control failure)
This kind of fault is a hardware fault. After the POST program issues a reset command to the controller, it does not get the interrupt response of the controller within the specified time. It may be that the controller is damaged or the cable is not connected. In addition, the controller control fails and the hard disk parameters. Whether the settings are correct or not is also relevant.
