U disk reload Windows system after the failure to run the problem of several reasons

1, the main boot zone data is corrupted

When the contents of the primary boot area are corrupted by a virus or tampered with by another program, the panic will not boot.

Solution: For the boot of the hard drive's boot zone to be compromised, we can fix it using the FDISK/MBR command, or use the KV3000 disk editing feature to find out if the other 62 sectors on the 0 0 side have a backup master boot program, restore it to 0 0-side 0.

　　2, the motherboard has failed

Mainly on the motherboard of the hard disk controller has problems, resulting in data transmission instability, error rate is too high, will lead to the phenomenon of no boot.

Workaround: You can check the motherboard manual for CMOS jumper information and clear the CMOS, but note here: You must unplug the host power cable when you clear the CMOS settings or set the power switch on the host to off or 0.

　3, hardware replacement or change caused by

When the host hardware configuration changes, after reloading the system will use the post function, but the system can not recognize the newly added hardware, or will be in accordance with the old configuration to start, so there will be no normal boot failure. (It may also be that the newly added hardware is not compatible)

WORKAROUND: Restore the state of the hardware before it changes and check to see if the system starts properly.

　4, BIOS setup Error

When the BIOS setup error, the hard disk mode settings when the error, the memory of the read and write parameters set error, etc. will cause the failure of the normal boot boot.

Workaround: You can try reconfiguring the "Pnp/pci Configuration" and "Reset Configuration Data" in the BIOS, with the option set to Yes and Enabled respectively. You can also make the BIOS option for the "Force Update ESCD" set to "Enabled", which can be tried in 2 settings, then save and then try to see if it starts properly.

Based on the above understanding, we can know that the U disk reload Windows system can not boot after a few reasons.
