? There are three reasons: (Before doing this, it is best to plug in the serial data cable and power cable of the hard disk again, and then plug them back, which can eliminate the phenomenon that the hard disk is not recognized due to poor contact) (The notebook skips this step)
(1) The first reason: If the first startup item of the motherboard BIOS is set incorrectly (generally set to CD-ROM and hard disk), the system will not start, so there is a cursor jump in the upper left corner:
Solution: Generally speaking, this is the way to deal with it, because there are two types of motherboards.
The first is the motherboard of Award 6.0: the setting is as follows: when the computer is just turned on, press the "DEL" key or "Delete" key and don't let go (of course, some computers are also an ESC, F 1, F2. F4, F 1 1, but most computers have been deleted. ) until the BIOS setup window appears, and then use the arrow keys. You find that "Advanced BIOS Function-Boot Device Priority-1ST Boot Device (1ST floppy drive stands for floppy disk SATA:SM-WDC WD5000 stands for hard disk CD/ DVD :PS-ATAPI IH stands for optical drive). Just press Enter here to select CD/ DVD or SATA, and then press F 10, it will appear. Generally, this setting can enter the system.
The setting of the second AMI 8.0 motherboard is as follows: when the computer is just turned on, press and hold the DEL key (some computers press F 1, F2, F4, F1,ESC, but DELETE is the most used one) until the BIOS setting window appears, and then use the arrow keys. You find Boot-Boot Settings-Boot Device Priority-Enter (OK)-1ST Boot Device-DVD/CD ROM (SATA: SM-WDCWD5000)-Enter (OK)) and press F 10 to select a good boot mode. Press F 10 to open an English dialog box. Select the "OK" key (it can be omitted) and press Enter. The computer will automatically restart, which proves that the changed settings are effective. Generally, this setting can enter the system.
(2) The second reason: The main reason for this phenomenon is that the master boot record (MBR) of the hard disk is wrong or damaged, so you should start with the reconstruction of the master boot record (MBR):
First of all, you should prepare the latest installation CD of GHOST version with PE, whether it is XP or WIN7 (general software stores or computer stores buy 5-8 copies) or prepare a USB flash drive with PE, then press F 12 or DEL to enter the BIOS, set the first startup item as CD-ROM drive (or USB flash drive), put it in (or insert a USB flash drive) and enter the CD-ROM drive. Enter WINPE, find a software called diskgenius, open this software, find your "hard disk", select your hard disk, right click, and a drop-down box will pop up, which reads "Rebuild Master Boot Record (MBR)". Click this "Rebuild Master Boot Record (MBR)" and a dialog box will pop up. Click "Yes" and it will pop up. Then restart the computer, your computer can reinstall the system, 95% can solve the problem.
(3) The third reason: If the above two methods can't be solved, it means that your operating system is damaged or poisoned, which makes it impossible to start the operating system, so you can only restore or reinstall the system with one click.
