How to install win7 on a hard disk

This method is suitable for 64-bit win7 or Vista installation. If it is installed on an empty disk (without any system hard disk), we recommend that you start it with a PE disc (USB flash disk) and perform operations in comparison to this article. If the hard disk already has an XP (x86) system and a 32-bit win7 or Vista, double-click the installation file setup. EXE.
1. Prepare the hard disk space.
The partition used to install Windows 7 is generally 30 ~ 50 GB in NTFS format. Because your computer has already installed XP on drive C, you must first prepare ~ 50 gb d disk or E disk to install win7. If the space of the D and E disks does not meet the requirements, adjust it. The adjustment method is as follows: first back up the data on disk D and disk E, then download the green version of Paragon partition manager, and use it to adjust the space on disk D or disk e to 30 ~ in Windows XP ~ 50 GB. The specific method can refer to this post part of the chapter: http://softbbs.pconline.com.cn/7307078.html

Use the ultraiso software or virtual optical drive to load the Vista ISO file and copy the bootmgr file and the boot, EFI, and sources folders to the C drive (sources only needs to copy the boot. wim file, the rest do not need to be copied, so you can create a folder sources on drive C, and then copy boot. wim file ).
③ Extract the win7 Installation File. Copy the Sources folder to the E disk in the same way as ② (you can also put it on the F disk, as long as it is not on the d disk to be installed in win7 ).
