The reasons why Win7 cannot boot may be as follows:
First of all, we accidentally touched the files on the system disk before shutting down, resulting in the inability to load files normally when booting up. As a result, the computer kept restarting to try to load files.
At the same time, when we use cleaning software to clean the registry, if we accidentally clean up the registration information of the startup software, the software will not be loaded when booting.
There is also the problem of driver loading. We installed an incompatible driver before shutting down. However, the system prompted that it was incompatible and we still chose to continue running, which resulted in the inability to boot.
The worst case scenario is that the system is infected with a virus. The anti-virus software deletes the virus-infected system files during anti-virus, so the system files are lost and the computer cannot be booted.
Solution
Principle: Important files in our system will be stored in a hidden disk, which can be automatically repaired when there is a problem with the system.
1. When turning on the computer, the system will display the following prompt because it cannot be turned on many times:
Start windows normally
Enable Windows automatic repair function
2. At this time, you need to select the automatic repair option. After selecting, the next thing to do is to enter the administrator account password. Only after entering the password can the automatic repair be performed normally.
3. After entering the password, the interface that pops up has an automatic repair option. Click Automatic Repair and wait for the automatic repair to complete.
During the repair process, a prompt box will appear, asking us whether to perform a restore operation. At this time, we must click Restore. Only by clicking Restore can the repair be performed normally. Restore is not to restore the system to its original state, but to restore the last correct operation.
4. After clicking the restore button, you can wait for your system to restart. After automatic repair, you can usually enter the system. It should be noted that this process may take a long time and requires patience.
5. If it cannot be completed, you can try the following operations.
(1)Enter safe mode
Press f8 when booting to enter safe mode. Under normal circumstances, as long as you successfully enter safe mode, you don’t need to do anything. Just restart the computer in safe mode and it will be OK.
(2) If you have installed some incompatible software or drivers, you need to enter safe mode to delete them.
