Can't from the hard drive of system analysis and solving start-up

Fault phenomena

PartitionMagic software will be used by the partition C FA32 converted to NTFS format after, restart your computer HP Laptop Battery, found the system cannot from hard drive in BIOS program, launched from floppy disks and set up systems respectively cd-rom start and equally, the whole system in self-inspection entered crash state after completion of the top of the screen, in addition, without any start the cursor signs of hard drive, and long bright lights.

Failure analysis

Judging from the fault phenomena, preliminary concluded that hard disk problems, heavy department off your computer HP Pavilion DV1000 Series Battery, enter BIOS setup program testing this hard disk parameters, find BIOS can correctly identify the hard disk parameters, will be hard disk parameter is set to "None", then set the system from cd-rom start, the computer can from cd-rom start, enter DOS state.

Shielding hard disk will start smoothly system, thus caused computers HP Pavilion dv2000 Series Battery can conclude disk is why cannot be started because of a malfunction in transforming division format appear after that in use, and preliminary partitionMagic software conversion process of division format, hard disk boot sector master boot record goods partition table destroyed, and system in start is needed to obtain hard disk of relevant information, read out if there will be a circular read, this probably dull hard disk lamp long bright.

troubleshooting

Solve times two kinds of the most simple fault is respectively: low-level format disk drives and use related software restore master boot record. If the data in the hard drive without reserve, can use DM software low-level format disk; If there are important hard disk data is need to use hp pavilion dv2000t battery the Lord direct giant deer recovery software restore master boot record. Below DisGen software restoring drivers use master boot record, specific operation procedure is as follows:

1, use USBoot software will U plate making as DOS startup disk, then will DiskGen software stored in making good DOS startup U plate.

7, press the ESC key, pop-up "information" dialog box, and then click "reboot" button can be successful repair master boot record.

8, after rebooting can from hard drive off your computer hp pavilion dv5000 series battery into the system.
