Comparison of several methods for installing Win7 system

　　I. CD installation method

Brief description: The CD-ROM installation method can be regarded as the most classic, compatibility best, easiest to learn the installation method. You can upgrade the installation, or you can install a new installation (you can choose to format the old system partition at the time of installation), and the installation method is flexible. Flexible installation of 32/64-bit systems without the limitations of the old system.

Method:

1, download the relevant system installation disk of the ISO file, carved plate standby. (There is a disc to omit this step)

2, the boot into the BIOS (general hardware self-test when the Del or F2 or F1 key into, different computer settings), set to the CD-ROM priority to start. Press F10 to save the exit.

3, put in the CD-ROM, restart the computer, CD-ROM guide into the installation interface. Follow the appropriate options for installation. When you choose to install a hard disk partition location, you can select a blank partition or an existing partition, and you can format the partition. Others are no longer detailed.

Disadvantage: In the WIN7 test version of the situation, this type of plate installation is undoubtedly the most extravagant, most wasteful, the most environmentally-friendly method. Recommended only if you do not have or are not competent for other installation methods.

　Second, analog optical Drive installation method (in specific cases may not be successful installation)

Introduction: Analog Optical Drive Installation method installation is the simplest, faster installation, but more restrictive, recommended for the installation of multiple systems.

Method:

Under the existing system with the analog optical drive program to load the system ISO file, run analog optical drive installation program, into the installation interface, upgrade the installation of C disk to leave enough space. Multi-system installation It is best to install the new system into a new, blank partition.

Disadvantages:

1, because the installation can not be installed on the existing system disk format, it is not possible to achieve a single system clean installation. It is also a waste of disk space because old system files occupy space. Have an old operating system.

2, due to the inability to format the old system partition, the residual virus files may endanger the security of the new system.

3, the old 32-bit system can not install 64-bit system, the old 64-bit system can not install 32-bit system.

　Third, the hard disk installation method (under specific circumstances may not be successful installation)

Hard disk installation method can be divided into two types:

1, the simplest hard disk installation method: The system to extract the ISO file to other partitions, the operation of decompression directory SETUP.EXE files, according to the corresponding steps, no longer detailed.

This method restricts and disadvantages the same analog optical drive installation method. The same cannot be formatted with the old system and 32/64-bit different systems can not be mixed. Recommended for multiple system installations.

2. Classic hard Disk Installation method: (similar to PE guiding principle)

Brief introduction: Installation is relatively troublesome, installation speed, can achieve clean installation, and Method 1 is different from the old system files, but the same 32/64-bit different systems can not be mixed.

Methods: The system image ISO files were extracted to other partitions, according to the old system is divided into the following XP system installation and Vista above the installation of the system.

1, XP and the following system installation, copy installation directory of the following files to C packing directory: bootmgr,boot, EFI Two folder, sources under the Boot.wim (placed in the C disk sources directory), run the following command: C:bootbootsect/ Nt60 C:

Reboot the computer to boot into WIN7 computer Repair mode, select the DOS prompt, delete all files under C disk, and run Setup under the installation directory.

2, Vista above the installation of the system, do not need to copy the above files, direct restart into the computer Repair mode, select a DOS prompt, delete all the files under C disk, run installation directory of the setup installation.

Disadvantages:

1, 32/64-bit different systems can not be mixed, because the different bit width of the setup and Bootsect programs in a heterogeneous environment can not run.

　　Four, the USB disk installation method (not volume production flash drive, strongly recommended!)

Brief Introduction: U disk installation method and CD-ROM installation advantages similar, but do not need to dial. More benefits than other installation methods:

1, not affected by the 32/64-bit system environment. If you install 64-bit WIN7 on a 32-bit old system, or 64-bit 32-bit WIN7, you will find that Setup is not running because 32-bit systems cannot run 64-digit programs. This method can solve all kinds of incompatible problems, and the installation speed is faster than the CD.

2, USB can be used as a first aid disk: In case the system crashes due to a variety of reasons can not start the system, then your USB drive is your first aid disk:

3. Easy to carry, one preparation, multiple installation. No, you can delete it at any time. There is a new version of the file can be updated.

4, this method also applies to the card reader and mobile hard disk, especially the mobile hard drive can greatly improve the installation speed.

5, can realize dual system, can also be a single system clean installation (format of the installation of C disk). This is determined by the option to install. As long as the computer can be USB boot, installation compatibility is best (similar to the CD installation).

Method:

1, under the vista/win7/2008 format USB drive, and the U disk partition set as the boot partition (this is the key to successful boot installation!), methods: "Computer"-> "Management"-> "Disk Management"-> point USB Drive partition, right key-> "format" and " Set as active partition. Disk Management does not operate with disk utility software adjustments. The traditional DiskPart method is not a necessary method and is not applicable to most people because of the command prompt operation.

2, the WIN7 of the ISO image file into the U disk, the simplest is to use WinRAR directly extract into the USB drive. or the virtual CD-ROM loaded after the copy into the USB drive. The USB drive installation disk is finished.

3, the computer set for USB drive (old computer USB-HDD set as the first guide, the new computer from the boot hard disk selected USB priority, depending on the BIOS), press F10 Save exit, restart the computer prompts step-by-step normal installation can be.

4, only for the capacity of the USB flash drive only the situation: You can only extract the key boot files (refer to the hard disk installation method, including Bootmgr,boot, EFI Two folder, sources under the Boot.wim, a total of 200MB), and the image of all the files extracted to the hard disk on other partitions, Boot successfully with a USB drive, select the computer Repair mode, into the DOS, run the hard disk WIN7 installation directory under the setup to install, but the installation will be more trouble point.

Disadvantages:

1, the biggest drawback is the need for a USB drive or mobile hard disk (believe this is not a problem for most people).

2, a very small number of computers can not be led by the USB (anyway I have not encountered), this situation had to be honest with other installation method.

　　V. Software-guided installation method (may not be successful in specific cases)

Brief introduction: Need external software to guide (see Attachment), no 32-bit/64-bit limit, can be single system or multiple systems, pure system clean installation, simple installation process.

Method:

1, with virtual CD-ROM loading system ISO image copy installation files or directly with WinRAR to the hard disk system partition root directory (not folder!)

2, download the attachment and run, according to the old system environment selection mode 1 or 2 (hint: If the final installation of multiple systems after the uninstall NT6 HDD installer boot menu preferably in the old system uninstall operation).

3, restart Select NT6 HDD Installer automatically enter the installation interface, no longer detailed. Mounted on the other partitions into a dual system, format C disk for a single system.

Disadvantages:

1, need external software.

2. A specific system environment/boot environment may cause the boot to fail.
