Windows7 installation methods can be divided into: CD installation method, analog CD-ROM installation method, hard disk installation method, USB flash drive installation method, software boot installation method, VHD installation method. Different methods have their own advantages and disadvantages. Before installing the system, it is important to prepare the necessary emergency disk and backup of the old system. In case of installation problems, it will not be caught off guard. The following detailed below:
an optical disc mounting method:
DESCRIPTION: disc mounting method can be regarded as the most classic and best compatibility, most easy to learn the installation method. Upgradeable installation, or new installation (optional formatting of the old system partition during installation), flexible installation. Flexible to install 32/64-bit systems without the limitations of the old system.
Method:
1, download the ISO file system installation disk, alternate dials. (This step can be omitted optical disc)
2, BIOS boot into (typically by hardware DEL key F1 or F2 or into, different computer settings self-test), the priority is set to start the drive. Press F10 to save and exit.
3, into the optical disc, restart the computer, CD-ROM guide installation interface. Install by the appropriate options. When you choose to install a hard disk partition location, you can select a blank partition or an existing partition and format the partition. Others are not detailed.
Cons: In the case of flying Win7 beta version, which dials installed is undoubtedly the most extravagant, most wasteful, least environmentally friendly way to go. It is recommended only if it is not available or is not suitable for other installation methods.
Second, the CD-ROM installation simulation method :( particular case may not be successfully installed)
Description: Analog CD-ROM installation method to install the most simple, fast installation speed, but more restrictive, recommended For multi-system installation.
Method:
loading system in the existing ISO file system, the operation simulation program installed CD-ROM drive with the simulation program installation interface, when the C drive upgrade installation space to allow sufficient . Multi-system installations preferably install the new system to a new, blank partition.
disadvantages:
1, since the existing system can not be formatted on the disk during installation, it is impossible to achieve a single system a clean installation. Because the old system files take up space, it also wastes disk space. Have an old operating system.
2, because the old system can not format the partition, residual virus files may endanger the security of the new system.
3, the old 32-bit system can not install the system 64, the old 64-bit 32-bit system can not install the system.
Third, the hard disk installation method :( particular case may not be successfully installed) be divided into two
hard disk installation method:
1, the easiest hard disk installation method: Extract the system ISO file to other partitions, run the SETUP.EXE file in the decompression directory, and follow the corresponding steps, no longer detailed.
limitations and disadvantages of this method with the analog drive mounting method. It is also impossible to format old systems and 32/64-bit different systems cannot be mixed. Recommended for multi-system installations.
2, and the classic hard :( mounting method works similarly to the guide PE)
DESCRIPTION: Installation is relatively cumbersome, faster installation, a clean installation may be implemented, and different methods of 1 The old system files are not left behind, but the same 32/64-bit different systems cannot be mixed.
method: Extract the ISO file system image to another partition, according to the old system is divided into the following install the system over XP system installation and Vista.
1, the following systems and XP installation, the installation directory the following files to copy the root directory C: BOOTMGR, BOOT, EFI two folders, boot.wim under SOURCES (SOURCES directory on the C drive) , run the following command: C:? ootbootsect /nt60C:
restart the computer to boot into Win7 computer repair mode, select the DOS prompt, delete all files in the C drive, run the installation SETUP directory for installation.
install 2, more than Vista system, do not have a copy of the above documents, the resumption of direct access to computer repair mode, select the DOS prompt, delete all files in the C drive, run the installation SETUP directory for installation.
drawback:
1,32 /64 Wei different systems can not be mixed, because of different bit widths and BOOTSECT SETUP program can not run in ectopic environment.
2, abort the installation process will render your system unbootable. So be sure to reserve an emergency disk.
