Problem three: "Resolving partitions cannot be partitioned, there are two more partitions in front of partitions"

Solution:

1. The partition mode used by machines pre-installed with Windows 8 is GUID mode (GUID reference: http://www.diskgenius.cn/function/guid.asp), in which the partition defaults to more than two partitions. However, this mode cannot be used when installing Win7, so it is necessary to change the mode to MBR mode to properly partition, as follows:

Use the partitioning tool first (take diskgenius4.0 here for example), all partitions are deleted (before the user must be prompted to save the data), then click "Save", save the left mouse click on the right side of the software, in the middle of the pop-up menu, there is a "conversion partition table type for MBR mode" as shown:

After this four-step operation can be normal partitions, it is recommended to use the fast partitioning function.

Question four: "Automatic restart of machines with Windows 8 Systems pre-installed"

A G480 factory with Windows 8 system machine, users said they do not want to use the Windows 8 system, their own use of ghost, installed a Win7 system will appear after the automatic restart phenomenon, and press F2 can not enable the BIOS phenomenon, appears as follows diagram interface, Continue to cycle and restart.

This prompt appears, because can not enter the system, but by the previous machine, even if unable to enter the system will not appear constantly automatic restart, and at most is to stay in the interface, and restart can press F2 into the BIOS; but this machine is not, is constantly restarted and press F2 and F12 have no reaction;

Solution:

Press the button to restore the machine, the machine will automatically boot, the following image will appear:

From that box can enter the BIOS, and then according to the above "on the Windows 8 to change the system" method set, you can use a U disk to boot PE, need to reinstall the system can be solved.
