A diskette from which you can boot your computer. Normally, your computer boots from a hard disk, but if the hard disk is damaged (for example, by a virus), you can boot the computer from a bootable diskette. For this reason, it's a good idea to make sure you always have a bootable diskette on hand. In Windows 95, you can create a bootable diskette by following these steps:
1.Insert a blank, formatted diskette in the floppy drive
2. Select Start->Settings->Control Panel
3. Open Add/Remove Programs
4. Select the Startup Disk tab and press the Create Disk
A bootable diskette is also called a bootable floppy, boot disk, and startup disk.
