Easily enter safe mode under dual system

Dual systems have become popular in the era. Many friends like to install dual systems or multiple systems on their computers. The small series of computers originally installed Win7 and XP systems, but the XP system is about to launch the stage of history, so it is replaced by Win8 and Win7 dual system. After using it for a while, I found that the computer is booting by pressing F8 or shift. +F8 can't enter safe mode. How should this go in?

1. First use the combination shortcut: window +R to bring up the run box, enter “msconfig”, then press Enter to run, as shown below:

2, you can enter the system configuration dialog box, then we click on the boot option, then select the boot item of the win7 system, put the security mode on the OK. Note: Which system is selected for which security mode to enter. As shown below:

3, after we restart the system, you can choose to enter the safe mode system, then the system will automatically enter the safe mode. As shown below:

Note here that after the safe mode is finished, remember to modify the boot item back, otherwise your computer will remain in safe mode. The steps are the same as the above operation, just cancel the check of the safe mode.
