The Absolute Minimum

  • You need to make sure your system meets the performance and free disk space requirements of a particular operating system before you install it.

  • You can install an operating system on an empty disk (clean install), as a replacement (upgrade), or as an additional boot option (dual boot).

  • Upgrades keep existing programs and data, whereas clean installs wipe out existing data and programs. Dual-boot installs don't affect existing programs and data, but can't run programs until they're reinstalled.

  • Windows 9x/Me use Setup.exe to start the setup process. Windows 2000 and XP also use setup.exe . Windows NT uses winnt32.exe or winnt.exe .

  • NTFS is the preferred file system for Windows NT/2000/XP installations, whereas FAT32 is the preferred file system for Windows 9x/Me installations except for early Windows 95.

  • Windows 9x/Me installations require the user to run Fdisk and Format first, whereas Windows NT/2000/XP installations can perform partitioning and formatting during installation.

  • Windows NT 4.0 and 2000 can create setup floppy disks if the CD can't be used for booting, but Windows XP requires the user to download bootable floppies if the CD can't be used for booting.

  • After a dual-boot installation, you must install the programs you want to use with the new version of Windows.

  • You can install Windows NT/2000/XP from a disk image onto multiple PCs, but you must change the SID (Security Identifier Number) to avoid duplication.

  • Detlog , netlog , setuplog , and bootlog (all .txt files) track activity and changes to a Windows 9x/Me computer during installation and startup. They are useful for troubleshooting.

  • Windows NT uses the $winnt.log , ntbtlog.txt , and setupapi.log files to track installation, setup, and startup activity. Windows 2000/XP use setuperr.log , setuplog.txt , setupapi.log , setupact.log , winnt32.log/winnt.log , and ntbtlog.txt to perform these tasks . They are useful for troubleshooting.
