Nowadays, it is not difficult for users to reinstall the system. However, many users complain that the system cannot start after reinstallation. It is a strange situation that the system cannot start after reinstallation. If you can't start after reinstalling, do you feel too blue, thin, and too mushroomy? How to deal with it? The following editor will tell you the solutions to the reasons why you can't start after reinstalling.

Solution to the problem of not starting after reinstallation:

After ghost is completed, the system cannot be started. If the system fails to start, it is caused by a problem with the MBR (Master Boot Record). After installing the system, the MBR is still old. If you want to get it right in one step, it is best to rebuild it before installing the new system. Take the MBR.

　

To rebuild the MBR, use a bootable USB disk to enter PE, start the hard disk partition tool, Diskgenius, and double-click to open it.

Open the hard disk menu of the software

Find the Rebuild Master Boot Record MBR option and click it.

If you do not rebuild the MBR before installation, it is likely that it will not start after the installation is completed. It is no problem. Use the above method to rebuild the MBR first, and then use the Windows repair program to repair it (if it is a GHOST system, GHOST After completion, a black screen appears and cannot be started. You only need to boot with a USB flash drive or CD, and then use DiskGenius to rebuild the MBR to start). MBR generally occupies one sector. It is determined when the disk is partitioned. It records the size, nature, starting point and end point of each partition. The MBR will not be changed even if it is formatted, and MBR has nothing to do with the operating system. In addition to repairing startup failures, rebuilding the MBR can also clear the system's main boot area Trojans, which cannot be underestimated.
