The easiest way to install Win7 with a mobile hard disk is

The speed of installing Windows 7 with a mobile hard disk is super fast. I usually install it for no more than 10 minutes.

A friend who has a usb mobile hard disk in hand can use it.

1. In vista or win7, go to Control Panel - Administrative Tools - Computer Management - Disk Management, right click on the partition of the usb mobile hard disk, click "Mark partition as active partition".

2. Copy all the files and folders in the windows7 installation disk (or the iso file directly, or use the virtual CD-ROM drive) directly to the usb mobile hard disk.

ok, can boot the usb hard disk installation disk is completed, set up the usb hard disk in the bios boot, directly start the installation program, it is so simple.

No third party software is needed at all. There is also no need to engrave.

The principle is very simple, the first step is to write the startup information. Activate the partition under vista/win7, then write bootmgr, if you activate the partition under xp, it is written to ntldr.

U disk can also be done, but copying small files is too slow, can not stand ~

The advantage of using an external device installation is that you can freely partition the hard disk in the computer ~
