At present, the market share of win 7 is about to become the first system by XP. Many people have used win 7, are you still embarrassed? Is it because XP is used to it, or is it not installed win7? Win7 installation is actually no trouble, no matter what system, the installation method is similar. There are also many ways to install win7. It is more convenient to use the hard disk to install win7. It is installed directly on the hard disk, does not require an optical drive, and does not require a hard disk. The following describes in detail the method and steps of installing Win7 from the hard disk under the old peach WIN7 PE. Follow the steps to do it, and it will succeed. Friendly tips: 1, hard disk space preparation. The partition on which the Win7 system is installed generally has a size of 30 to 50 G and is in the NTFS format. Format the C drive under PE, section: http://softbbs.pconline.com.cn/7307078.htmlParagon Partition Manager 7 green version can be downloaded here: WINPM.rar http://img.pconline.com.cn /images/bbs4/attachment/20092/12/1234426021995.rar 2, Win7 file preparation. 1 Download the ISO file of Win7 to the local hard disk. 2 Extract the Win7 startup file. Load Vista ISO file with UltraISO software or virtual CD-ROM drive, copy bootmgr file and boot, efi, sources folder to C drive (source only need to copy boot.wim file, the rest do not have to copy, so you can create a new one in C drive in advance) Folder sources, then copy the boot.wim file into it). 3 Extract the Win7 installation files. Copy the sources folder to the D drive in the same way as 2 (you can also put it on the E, F drive, etc., as long as it is not placed on the C drive to be installed on Win7). 3. Win7 startup format preparation. Open the command line window in XP system (method: start → run, fill in CMD and then press Enter), type the command in the command line window and press Enter: c:\\boot\\bootsect.exe /nt60 c: Note: If Install 64-bit Win7/Vista because the bootsect.exe in the system image is 64-bit and cannot be run on a 32-bit system (if it is installed on an existing 32-bit system). Here is a 32-bit download for everyone, so you don't have to look around. Please install 64-bit system users to download and use, after unpacking, overwrite the 64-bit bootsect.exe in the boot folder.

After the startup is completed, the Win7 installation interface will pop up. Click “Next” & rdquo;→“Repair the computer”→“No”→“Next”→&ldquo ; command prompt & rdquo;, pop-up command line window. 5. Clean up the startup files. (Do not do this step is not big) You must delete the bootmgr file and the boot, efi, and sources folders that were originally copied to the C drive, so as to avoid the startup file confusion when installing Win7. Type the command in the command line window and press Enter: del c:\\bootmgrrd /s c:\\bootrd /s c:\\efird /s c:\\sources 6. Format the C drive. (It is better to format the C drive after starting the system installation program, so this step can also be skipped.) Type the following command and press Enter: format d: /q /fs:ntfs If the D drive is already in NTFS format, You can not add /fs:ntfs this parameter. If the D drive is empty, you don't have to format it, skip this step. 7. Run the win7 installation command. Type the following command and press Enter: D:\\SOURCES\\setup.exe (only the SOURCES folder is required in the D drive) 8. Complete the installation. Follow the prompts to complete the win7 installation step by step, the process is the same as the CD installation. Author jaychang
