Install the original Win7 three-class method

The first method:
Native U disk installation, the U disk boot menu created by this tool contains Windows 7 operating system installation function, use this function to transplant Win7 system to your U disk perfectly. in. This function does not need to enter the PE without a virtual CD-ROM drive. It is not restricted by the FAT32 and NTFS file systems. It is not necessary to format the U disk again. The speed is much faster than the CD-ROM installation. It is a pure USB disk installation. Since the disk order has been exchanged in the startup command, there is no case where the first disk is a USB disk during the installation (the real machine test passes, do not test the installation method under the virtual machine).
Specific steps:
1, first use the old peach U disk boot production tool to make the U disk boot.
2, find the iso image of Windows7, open the iso image of Win7 with UltraISO or WinRAR, and then extract /extract all the files to the root directory of your U disk.
3, finally found a file named bootmgr in your U disk, rename bootmgr to win7mgr.
4, start the computer with a U disk, select menu 11, and then select menu 2 to directly install the Win7 original operating system.
The following steps are not much different from installing with a CD. When the installation process is automatically restarted, the U disk can be removed and the installation can continue.
