I. Two system installation methods:
(1) EFI + GPT
(2) legacy + MBR
GPT and MBR are in hard disk mode.
If you have installed 32-bit Win8, your hard disk partition is still in MBR mode.
Only when you have installed a 64-bit Win8, your hard disk partition may be in GPT mode.
II. Three methods for converting GTPs to MBR1. Third-party software Law
If you have a PE with the win7 Kernel on hand, you can enter the PE environment and use diskgenuis to adjust it.
Note that you must delete all hard disk partitions to complete the conversion.
2. Installation Procedure for Windows
You can delete all partitions in the win7 installer and create new partitions directly.
Generally, GPT can be directly transferred to MBR.
3. diskpart Method
If none of the above methods works, use the win7 CD. Note that the original version is required.
After the installation program is started, press shirt + F10 to Enter cmd.
