A bootable disk is A CD-ROM or DVD-ROM that contains its own operating system ready to load. PCs are typically configured to look for the OS on a CD or DVD first and then the hard disk. Newer machines can also boot from a flash memory-based USB drive.
Booting from removable media such as a USB drive allows you to perform diagnostics on a computer that is having trouble booting from the hard drive. You can also use the flash drive to install Windows, instead of using the Windows installation CD.
Step-by-step Process to Create a Bootable USB Flash Drive for Windows 10:-
Step1:- First You must have Windows 10 ISO Image ( Download Now) and 4 GB USB Flash drive.
Step 2 :– Navigate to https://rufus.akeo.ie/ and download Rufus tool, Rufus is a utility that helps format and create bootable USB flash drives, such as USB keys/pendrives, memory sticks, etc.
It can be especially useful for cases where:-
- you need to create USB installation media from bootable ISOs (Windows, Linux, UEFI, etc.)
- you need to work on a system that doesn’t have an OS installed
- you need to flash a BIOS or other firmware from DOS
- you want to run a low-level utility
Once you have done this, simply click on Start and wait for the process to get over. Remember that when you click Start, all data preset on this USB will be deleted, so if you need to, you may back up your data first before using it.
Once the process is completed, you will have a bootable Windows 10 installation USB media in your hands, which you can use to install Windows 10. If you feel the need, you may check if the USB is bootable.
Step 3 :– To boot from a USB drive:-
Every Windows PC is different, but once you get into your system’s boot menu you should be able to find what you’re looking for. To boot from a CD or USB drive:
Restart your computer and wait for that first screen to pop up. Often, it’ll say something like “Press F12 to Choose Boot Device” somewhere on the screen. Press that key now.
Give it a moment to continue booting, and you should see a menu pop up with a list of choices on it. Highlight your CD or USB drive and press Enter.
You should see a new screen pop up, called your BIOS. This is where you set a lot of low-level settings for your computer. Look through the options (being careful not to change anything) for a setting called “Boot Device,” “Boot Order,” or something similar. Select that option.
From the menu that pops up, choose your computer’s disc drive and press Enter. If you’re trying to boot from a USB drive, choose USB-HDD instead and press Enter. Depending on your BIOS, you may need to use the Page Up and Page Down keys to move your selection to the top of a list, instead.
Exit out of your BIOS, saving your changes. Usually, this option is under “Exit” on the main menu, or available via a keyboard shortcut listed somewhere on your screen.
Your computer should reboot. Make sure your CD or USB drive is in your computer. If you’re prompted to “Press any key to boot from CD/DVD,” do so. Your computer should boot into the CD or USB drive instead of your normal operating system.
