Emergency - Contingency Plans
If your computer ever fails to comply with your wishes to start working, you might have to try to start it up using a different disk. Computers are instructed to run through their bootstrap procedures (boot process) by reading instructions from the hard disk drive. If that drive ever becomes inaccessible or can't find its data, you will need a "Plan B". One of the first things you should do with your computer system is to create a "Boot Diskette" that will allow you to start the computer and probe around and possibly fix the problem. To create a boot diskette, you will need to follow these steps:

Installing and Uninstalling
Software
InstallingMost software that you purchase will be distributed on CD-ROM or Diskette Sets. If the software is distributed on CD-ROM, inserting the disk into the CD-ROM drive will probably launch the setup process. All you will have to do is watch the screen and agree to a few questions. The program will be automatically installed and additions will be made to the menuing system. Software that is sold on diskette sets will not activate the self-installation procedures. You will have to do this manually. Follow these easy steps:
UninstallingIn the event that you wish to remove software from the computer, most commercial products build in an Uninstall routine when they are installed. To best method of accessing this routine is to open the Control Panel. Click the Start Button, move the mouse pointer upward until it is on top of the word "Settings". A submenu will appear that contains the Control Panel icon. Move your mouse to the right until the arrow is over the Control Panel Folder and then click the left mouse button once. Doing so will bring up the following screen: Clicking the "Add/Remove Programs" icon will then allow you to uninstall software from a list. Carefully choose the software package that you want to remove and then click the "Add/Remove" button. The computer will take care of the rest. It is a really good idea to make sure that you don't have the program running on the computer when you try to uninstall it. |
