How to Boot Computer from CD or USB Flash Drive?

Sometimes you need to boot your computer from a bootable CD or USB flash drive. For example, if you're troubleshooting your computer or installing a new operating system, you'll need to boot your computer from a system repair or installation disk. In this tutorial we'll show you how to do it.

Most recent computers have a boot menu. The boot menu enables you to choose the boot mode. You can follow the steps listed below to enter boot menu and boot your computer from CD or USB flash drive.

Boot Menu

1. Insert bootable CD or USB flash drive.
2. Power on or reboot.
3. Press Boot Menu Key, usually Esc or F12 when the display starts.
4. Select CD/DVD or USB option, and then press Enter key.

The first two steps are self explanatory. Step 3 is just a matter of knowing the right key to press. Step 4 could be somewhat confusing because not every PC manufacturer uses the same terminology to describe the boot device. You can search the boot menu key(s) of your computer below.

The tables below offer assistance with step 3. The "Boot Menu Key" column shows the known boot option keys for various computer manufacturers. When you are trying to get to the boot menu, reboot and press the first key repeatedly as soon as the display flashes or is no longer blank. If that does not work, reboot again and press the next listed key immediately after the display becomes active. After you enter the boot menu, you need to choose the CD/DVD or USB device option. Usually, this device is listed as "CD-ROM", "USB" or sometimes "Patriot Memory".

Most computers also allow you to change the boot "priority" in BIOS so that the CD or USB flash drive is preferred over the local hard drive. The "BIOS Key" column shows which key can be used to enter the BIOS setup menus in order to change the boot device sequence. You can follow this tutorial to change the setting: BIOS Settings for CD/DVD or USB Flash Drive
