Reasons and solutions for Win7 pure system not being able to boot after reinstalling

1. The motherboard has a fault

The main problem is that the hard disk controller on the motherboard has a problem, causing the data transmission to be unstable and the error rate to be too high, which will result in the failure to boot.

Solution: You can check the motherboard manual for CMOS jumper information and clear CMOS, but here you should pay attention: when clearing the CMOS settings, you must unplug the host power cord or set the host power switch to off or 0.

2, caused by hardware replacement or change

When the hardware configuration of the host changes, the POST function will be used after the system is reinstalled, but the system will not recognize the newly added hardware. It will still start according to the old configuration, so there will be a failure to boot properly. (It may also be that the newly added hardware is not compatible.)

Solution: Restore the state before the hardware change and check if the system can start normally.

3, the data in the main boot area is corrupted

When the content of the main boot area is corrupted by viruses or tampered with by other programs, it will cause the crash to fail to boot.

Solution: For the boot program of the hard disk's main boot area is destroyed, we can use the Fdisk/MBR command to repair, or use the KV3000 disk editing function to find the other 62 sectors on the 0-side 0 side. There is a backup main boot area program, which can be restored to 0 0 0 area 0.

4, BIOS setup error

When the BIOS setting error, the hard disk mode setting is wrong, the memory read and write parameter settings have errors, etc. will cause the failure to start the boot normally.

Solution: You can try to reconfigure the BIOS to "PNP/PCI configuration" and "Reset Configuration Data", the option settings are “YES” and “Enabled”. You can also set the BIOS option of “Force Update ESCD” to “ld”; Enabled”, you can try these two settings, then save and exit, and then try to see if it can start normally.
