If you are using a windows PC then you can easily boot from disc drive or you can also use bootable USB drive. Every Windows PC is different, but the process for booting from usb and boot from cd Drive is same. To boot from a CD or USB drive – boot from CD or booting from USB:

  1. To access the BIOS, you’ll need to restart your computer and press a specific key at the start of the boot process. This key is generally displayed on-screen during the boot process. For example, you may see a message that says “Press <DEL”> to enter setup” or “Press F2 to access the BIOS.” Press the required key at the correct time and your computer’s BIOS will appear.
  2. While Delete and F2 are probably the most common keys, your computer may require another key, such as F1, Escape, or Ctrl+Alt+Escape.
  3. 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.

Alternatively, you can set your computer to always check for a bootable CD or USB drive. That way, when you have one inserted, it’ll boot from it automatically, and when you don’t, it’ll head into your regular operating system. To set this up, follow these instructions:

  1. Restart your computer using the keys indicated above in the 2nd step.
  2. You should see a new screen pop up, called your BIOS.
  3. Once you’re in the BIOS, look for some sort of “Boot” option menu.
  4. Look for a setting called “Boot Device,” “Boot Order,” or something similar. Select that option. Use the arrow keys to navigate through the BIOS. To select something, press Enter.
  5. You will see a list of the keys you can use at the bottom-right corner of your screen.
  6. Now Locate the boot order screen that lists the boot devices.
  7. 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.
  8. Select an option and press Enter to change it, either to disable it or specify another boot device. You can also use the + and – keys to move devices up or down in the priority list. NOTE: Keys differ from one keyboard to another.
  1. Note that “USB drive” doesn’t appear as an option in the list, even though our computer has USB ports. If we connected a USB device to the computer before starting our computer and accessing this screen, we’d see the USB drive option in the list. Some computers display the USB drive option even when a drive isn’t connected, while some don’t.
  2. The boot order is a priority list. For example, if “USB drive” is above “hard drive” in your boot order, your computer will try the USB drive and, if it’s not connected or no operating system is present, boot from the hard drive.
  3. Exit out of your BIOS, saving your changes.
  4. Select the Save Changes and Reset or Save Changes and Exit option and press Enter to save your changes and restart your computer.
  5. Your computer should reboot.
  6. 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.
  7. Your computer should boot into the CD or USB drive instead of your normal operating system.
