If you encounter a Win7 system crash, you can't boot, enter safe mode, and you can't repair the system. In the face of this situation, I am afraid it is not a system problem, it is a hard disk damage problem. Below, the ink dye warm heart teaches you to judge what is the cause of the above phenomenon. First determine whether the hard disk is damaged, it may be hard disk necrosis, or it may be bad sectors of the hard disk. If it is not a hard disk damage problem, then you can reinstall the system. First, determine whether it is hard disk necrosis 1. Insert the U disk boot disk into the computer USB interface. PS: If there is no U disk boot disk, you need to make the U disk into a U disk boot disk on other computers that can be used normally. 2. Press the power button, quickly press the DEL button on the keyboard or the F12 button (before the computer enters the startup program), enter the BIOS setup interface, find the BOOT column, the option with the USB word or the U disk brand The option is set to the first startup item, and press F10 to save and exit (for details, please refer to the prompt on the BIOS interface) as shown in Figure 1: Figure 1 BIOS setting U disk as the first boot disk
PS: different The method of entering the BIOS of the motherboard may be different. At the same time, the options for setting the USB flash drive to the first boot disk are different for different motherboard BIOS settings. The specific BIOS setting method of the motherboard can be searched in this site. 3. After the setup is completed, the system will automatically restart, enter the pocket PE function selection interface, use the arrow keys on the keyboard to select “Start Pocket U disk Windows8PE maintenance system”, and press the Enter key, as shown in Figure 2: 2 pocket PE function selection interface
4. After entering the pocket USB flash drive Windows8PE maintenance system, double-click the “Computer” on the desktop, in the open computer window, see if the disk is reduced, that is, if the drive letter disappears. If it does not disappear, consider the problem of the bad sectors of the hard disk. If it disappears, the hard disk is necrotic. Second, determine whether it is a hard disk bad track 1. Then just step, close the computer window, double-click to open the icon named "DiskGenius" on the desktop, as shown in Figure 3: Figure 3 Open DiskGenius
2. DiskGenius window, select “hard disk”→ in the hard disk drop-down menu, select “ bad track detection and repair & rdquo;, as shown in Figure 4:
Figure 4 select “ bad track detection and repair & rdquo; Br> 3. Next, follow the DiskGenius prompt, step by step. The process of bad track detection and repair may take about 2 hours depending on the size of the hard disk. You need to wait patiently. PS: If the final test results show that the hard disk has no bad sectors, then you need to consider the problem of the installed Win7 system. It is recommended to reinstall the system. Third, reinstall the system At this time, considering the simplicity of reinstalling the system, you can only choose the two methods of disc reloading system and U disk reloading system. Tutorials for reinstalling the system can be found on this site, and each tutorial can be successful through practical operations. The system image of the reinstalled system can also be downloaded from this site.
