How to boot from the USB flash drive?

 
BIOS is an acronym for Basic Input/Output System and also known as the System BIOS, ROM BIOS or PC BIOS. When you turn on your PC, its BIOS runs a power-on self-test (POST) to ensure that the machine’s devices are connected and working properly. If the test finds no problems, the BIOS turns over control of your PC to another piece of software, typically the operating system.
 
If you want to boot from the USB flash drive, remember to set the USB flash drive to the first boot device. Here is how you can do this:
 
Step 1. Plug the USB into a USB port, then start your computer and continuously press a key on the keyboard before the BIOS hands over control to Windows. You have only a few seconds to perform this step.
 
Kindly Remind:
Pay close attention to the first screen that appears. Look for a message that indicates which key you need to press in order to access the BIOS. That key is likely to be a function key such as F1, F2, or the Delete key. On some computers, entering the BIOS may require pressing another key or a combination of keys. Keep your eyes open for an on-screen message that says something like: Press F1 to enter setup, BIOS settings: Esc, Setup = Del, System configuration: F2.
 
Step 2. Select Boot Device. Look through the options (being careful not to change anything) for a setting called “Boot Device,” “Boot Order,” or something similar. Select that option.
 
Step 3. Choose USB-HDD 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.
 
Step 4. 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.
 
Step 5. Reboot your computer. Make sure your USB drive is in your computer. Your computer should boot into the USB drive instead of your normal operating system.
 
Then you will see the main page of the Partition Wizard boot edition. With its Partition Recovery feature, your accidentally deleted system reserved partition Windows 10 could be recovered.
