How to Make a Bootable USB Drive
Many modern computers are shipped without a floppy drive. This can be a pain for anyone who needs to use a boot disk to rescue a system. This how-to will walk you through making an old fashioned DOS boot disk--on a USB key.
Things You'll Need
- HP USB Disk Storage Format Tool (download from resources link below)
- Windows 98 system files (download from resources link below )
- A USB drive, no bigger than 2GB
Insert your USB key into the computer, and open the HP USB Disk Storage Format Tool.
Make sure your USB key is selected under the "Device" section at the top of the window. Select FAT32 as the file system.
Select the checkbox for "Create a DOS Startup Disk," and the radio box for "using DOS system files located at..."
Browse to the location where you extracted the Windows 98 system files you downloaded.
Click the Start button, and confirm that it is OK to erase all data on the USB key. When the process has completed, your USB boot disk is ready.
Tips & Warnings
- Not all computers will support booting from a USB device. Most anything less than three years old should be fine, but older machines may need a BIOS update first, or might not support it at all.
