Normally, system reinstalling refers to computer operating system reinstalling. It has to be reinstalled due to improper operation, virus attack, Trojans which lead to file damage or system crash.

What is system reinstalling?
System reinstalling refers to, fundamentally, format disk that system exists (usually disk C), then copy new system into formatted disk. When installing operating system, user always encounters various installing ways like clean installation, upgrade installation, install under Windows or DOS, definitions are as follows:

  • Clean installation refers to install another operating system beyond previous operating system, namely, multiple operating system coexistence. Clean installation is the ideal option for those users who still want to use previous system or feel worries about new operating system and merely like to try the new system. Clean installation is of high safety and harmless to previous system, such as Windows 98/2000/XP.
  • Upgrade installation refers to upgrade previous operating system, for example, upgrade Windows 98 up to Windows 2000 or Windows XP which bears advantages of retaining original programs, data, settings and of few compatible problems, disadvantage of difficult to recover once upgraded.
  • Installation under Windows is the simplest installing method which merely requires inserting installing CD and running installing program, familiar in interface and simple in operation.
  • Installation under DOS is an installing way for computer masters, which is performed under a heap of DOS prompts. Generally, user only need to set it as CD driver steering in BIOS and start system with Windows installing CD, then installing program would run automatically; or user could manually run Setup.exe program under Windows.
