1 Review last lecture Pre-installation checks

2 Post Installation Identify installation problems Install patches, upgrades, service packs MS announces patches for individual patches, bundle many patches together into service pack, patches and service packs can be downloaded and installed as updates Install or upgrade to the latest device drivers Restore user data files if necessary

3 Installing/Upgrading Win 9x/Me

4 Pre-Installation Must follow checklist of items before installing O/S (refer to previous lecture) Follow this checklist for Win 9x/Me

5 Minimum Hardware Requirements MS gives very low hardware requirements for Win 9x/Me Different MS documentation (online, printed) give different values Refer to official values in handout (left column) Compare them to more realistic values in the right column

6 Setup Disk Win9x/Me can only be installed on a partitioned, formatted hard drive All Win9x come with setup boot disk Boot disk detects unpartitioned/unformatted drive, asks if you want to partition and format

7 Setup continued Win Me CD is itself bootable, allows you to prepare the hard drive Both Win9x and Me can be installed on a pre-existing FAT partition Refer to figure 14-3 start up screen for win 98

8 Setup cont. Instead of using setup disk, boot directly from CD-ROM Your pc must be able to boot from CD drive (check CMOS) Note: Win 98 and Me CD-ROMs are bootable, Win 95 installation CD-ROMs are not-must use bootable floppy

9 File System: FAT16 vs FAT32 Always use FAT32 for clean install and upgrade 2 main reasons for keeping 1 FAT16 partition: –Use a previous version of MS-DOS to run old DOS programs –Your version of Wn95 might not support FAT32

10 Installation Process Clean install begins in text mode refer to figure 14-3 After reboot, installation proceeds in graphic mode If setup started, will prompt you to partition and format drive Follow instructions Installation tip: copy all install files to hard drive. Start install from there. Makes install faster ScanDisk started, checks for monitor and mouse, loads important install files

11 Graphical Mode Prompt for Component Options Refer to Setup options on page 615 Users familiar with Win can choose custom to configure and install specific components Compact option does not install many features needed by users

12 Continued Prompt for product key Installation directory (fig 14-8): –Clean install always asks for a directory (default C:\Windows) Same folder must be used when upgrading from Win95-98 If different folder used, clean install of Win 98 occurs

13 Continued Prompt to create a start up disk: –Different from Win boot disk, cannot run setup from start up menu –Copies some useful utilities Prompt to save system files, allows you to uninstall win 98 or win Me from the control panel

14 Hardware Detection Plug-N-Play feature searches for hardware and installs appropriate drivers Will prompt the user for driver disk if not present on the hard drive

15 Win NT 4.0 Workstation Most install steps are the same as Windows 95 NT usually installed on older machines NT is NOT plug-n-play Must check the NT Hardware Compatibility List HCL is located on the CD ( \Support\HCL.HLP)

16 NT 4.0 Cont. List the minimum requirements on page 617 NT supports FAT16 and NTFS4 file systems NTFS recommended because improved security and stability + supports partitions larger than 2 GB

17 NT 4.0 Cont. NT assumes your are installing on a networked computer NT can be installed on standalone pc (install process gives you the option to skip the network setup) MUST install all patches and upgrades since NT is very old Service Pack 6a contains all the latest upgrades and patches

18 Win 2000 Professional Before installing, check that system meets minimum requirements (page 618) Hardware must be supported by Win 2000 OS Verify compatibility by checking the HCL

19 Win 200 Pro Cont. Installation process begins in text mode, reboots, continues in graphics mode SETUP.EXE examines HD to determine existing partitions and file systems Option to install on existing partition or create new partition for installation Boot partition should be at least 1 GB

20 File Systems (Win 2000 Pro) Supports FAT16, FAT32, NTFS FAT: Win 2000 setup will automatically format HD with FAT16 if partition is less than 2 GB and FAT32 if partition is more than 2GB

21 NTFS5 Advantages: –Assign disk quotas to users –Encrypt files, folders –Support Win 2000 Dynamic Disk configurations

22 Networking (Win 2000 Pro) Win 2000 is optimized for networking with other computers Following are installed by default: –Client for Microsoft Networks –File, printer sharing for Microsoft Networks –Internet Protocol (TCP/IP) You are given the option of joining a workgroup or domain

23 Win XP Pro Can upgrade from the following versions of Windows: –Win 98 (all versions) –Win Me –Win NT 4.0 Workstation (Service Pack 5 and later) –Win 2000 Pro (including service packs) –Win XP Home Edition

24 XP Pro (minimum requirements) List from page ….

25 Windows Installation/Upgrade

26 Preparation “Prior planning prevents poor performance” Installing an O/S – must follow a detailed checklist for the best result Following tasks must be performed even before you insert CD-ROM

27 Identify Hardware Requirements Help you to decide whether a system is a suitable host for a particular operating system. Requirements include: 1.CPU model 2.RAM 3.Free hard disk space 4.Video adapter 5.Monitor 6.Other storage devices, drives needed to install and run O/S

28 Hardware/Software Compatibility Must make sure that the hardware and applications are compatible with O/S you wish to install 2 sources for this info: –Microsoft –Manufacturer of device or software Check Microsoft’s Hardware Compatibility List on the web microsoft.com

29 Cont. If your device not listed in HCL, consult CD-ROMs provided by manufacturer for drivers Check manufacturers web site for latest drivers For software, manufacturer should provide upgrade packs.

30 Clean Install/Upgrade Clean Installation means completely empty hard drive with no O/S installed Upgrade means installing newer version of Windows O/S on top of existing O/S

31 Clean Install Advantage: no problems carried over from the old operating system Disadvantage: all applications have to be reinstalled, each application reconfigured to user’s preferences Must format and partition hard drive from scratch

32 Multi-Boot Variation of clean install Install O/S into a different subdirectory or onto a different volume on hard drive Old O/S is still intact Use boot menu to select the O/S at start up Not recommended

33 Upgrade New O/S installs into same folders New installs on top of the old Old O/S replaced but data, settings for hardware, applications saved To begin upgrade, run appropriate program from CD

34 Back up/Restore Existing Data Back up user data in case hard drive is damaged Find out if user is saving data locally or network drive If data saved locally, hard drive must be backed up After installation, restore data to local drive

35 Select Installation Method How you start installation Location of source files Manual, Unattended (automated)

36 Bootable CD/Boot Floppy Upgrading: run set up program from within old O/S Clean install: –No existing O/S to run set up

37 Other Install Methods In large organizations, not feasible to install on each individual machine Source files placed on a shared directory on network server Installation may proceed according to a special script (automatically select options and components needed) Scripts can even install specific applications without user input

38 Image Install Image is complete copy of a hard disk volume on which an O/S and applications are preinstalled Images can be on CD-copy image to local hard drive using special software Images on network servers-connect to server and copy image to local drive using special software

39 Partition Hard Disk/ Choose File System Clean Install: must choose file system before partition (how many, what size) No Mulit-Boot:use most advance file system your version of Windows supports Multi-boot: Lowest common denominator rule, choose file system so that boot sector must be usable by oldest O/S Once file system selected, size and number of partitions can be decided
