Win7 avoids MB of hidden space

In fact, it is very easy to avoid the M hidden space problem in win7, that is, do not perform partition operations during the installation process. That is to say, before installation, you should use WinPE, if you still want to use other systems, you should first plan the capacity of the partitions that need to be installed with Win7, format the partitions (NTFS), and install them directly in the partitions you have divided. This will be okay. If you use the Win7 installer to perform partition operations (delete, create, and format) during installation, the M hidden partition will be installed on the new hard disk Windows 7, by default, the built-in de partition tool creates a new MDE hidden partition de. Is it true that de will use the xp partition and then come back to install Windows 7? In fact, you don't have to. Just use these commands. Start the CD, install Windows 7, and go to "Install Windows There" de, now we can see deshi a non-allocated de disk. Press the shortcut key "Shift + F10" to open the CMD command line, enter "diskpart", and enter the diskpart command window. Run the following command: www.2cto.com> list disk -- view the hard disk number and size. If you have a USB flash drive, identify the disk. > Select disk 0 -- select the hard disk number so that it is in the focus state, just as if you left the mouse to select the target. > Create partition primary size = 20481 -- create a primary partition. The size of the number shi after the primary partition is in MB. > Format fs = ntfs quick -- format the primary partition in ntfs format. > Create partition extended -- create an extended partition. > Exit -- exit the program.
Close the CMD command window and refresh the selected installation partition. Install the command in the first primary partition to avoid MB of hidden space and create the extended partition. 20G should be 20 19.9 MB before shi de is correct, but this integer will be displayed as 20.0G after entering Windows, and as long as more than 1 m will be displayed as G. After the experiment, whether you are creating a 10Gde partition or a shi100Gde partition, adding this 1 m can avoid the x9.9M problem. This is very different from the de formula 1024n + 4 (n-1) in Windows XP and shi.
