Don't Have CD/DVD,Format your computer with Flash Drive in just 11 Steps...
1- Decide on the purpose of your flash drive. To create an MS-DOS bootable
flash drive, you will need a blank flash drive, as well as the HP USB
Disk Storage Format Tool and the Windows 98 MS-DOS system files.
2-Download the system files. WindowsXP/7/10 system files can be found for free on the internet. They are completely legal to download.
The files will most likely download as a .zip file. Extract this
file into a temporary folder that you can easily navigate to, such as on
your desktop. You can delete this folder when you are done making the
3- Download and install HP USB Disk Storage Format Tool. This is a freeware tool created by Hewlett-Packard that will allow you to quickly format any flash drive. You will need it to create a flash drive with a boot sector. Insert the flash drive you wish to use into the computer and run the Format Tool.4- Under “Format options,” check the box that says “Create a DOS startup disk.” Then, click the “…” button under “using DOS system files located at:”
- Choose the flash drive from the “Device” drop down box. Make sure that the correct drive is selected.
- The second drop down box, “File System,” should be changed to FAT32
- Navigate to where you have downloaded the Windows 98 MS-DOS system files. Select the folder and hit “OK.”
6- Plug in the flash drive. Make sure that it is plugged into the computer itself and not through a USB hub.
7-Turn on the computer. Every computer manufacturer has a different boot screen. As soon as you see the logo, you will need to hit either F2, F10, or Del to enter the BIOS menu. These are the most common keys for entering the BIOS menu. The key you need to press will be displayed under the logo.8- Find the Boot menu. If you hit the correct key at the correct time, you should now be in the BIOS menu for the computer. This is where basic computer functions are set, before an OS (Operating System) is loaded. Navigate to the Boot menu. Every manufacturer has a different BIOS setup. Some have the menu in a column; others have tabs across the top.
- This part of the boot process can occur quickly, and you may have to restart the computer if you missed the chance to enter BIOS.
9- Change the boot order. Once you are in the Boot menu, you will see a list of devices. This is the order of devices that the computer will attempt to find an OS on. Typically, the first device listed is the computer’s hard drive, usually followed by the CD/DVD drive.
- Select the first boot device and change it to your flash drive. The menu will either say “Removable Device” or will display your flash drive’s model name. This will make the computer check your flash drive first after turning on, instead of the hard drive.
- Saving and exiting reboots your computer
11- Wait for your flash drive to load automatically after the reboot. After a few seconds, depending on what your flash drive is made for, you will be given control. If you made an MS-DOS flash drive, you will be given a command prompt after booting. If you made a Windows 7 install flash drive, the install process will begin automatically.
