the other is to adjust the boot order in BIOS
start the computer and press the "del" key to enter the BIOS interface of the motherboard. Read your motherboard manual and choose the boot order. Take award BIOS as an example: enter the BIOS interface of the main board, select "advanced BIOS features", select "boot sequence" on the "advanced BIOS features" page, and press "enter" to enter the "boot sequence" interface, with "1st / 2nd / 3rd boot device" option, This option allows you to set the order of BIOS boot devices to be loaded into the operating system, select "1st boot device" (use "page down" or "page up" key to set it to "USB HDD", press ESC key to return to the main menu of BIOS, press F10 to save and exit BIOS, restart the computer,

set the USB flash disk to start:
A. when the main board self-test screen or brand logo screen appears after power on, quickly and continuously press the BIOS hotkey (different brands and models of computers have different BIOS hotkeys, generally F2 for laptops and del for desktops) to enter the BIOS setting interface
B. press the left and right arrow keys to move and enter to enter the boot (or startups) tab. Press the up and down arrow keys to select the boot option, press the + or - key to move the boot option, and set the USB disk (usb-hdd, usb-fdd and other formats are preferred) as the first boot item. Press enter to confirm (Note: some computers need to insert a USB disk at this time for recognition). Some old motherboards need to enter the advanced BIOS features tab, press enter at "1st boot device", and then select usb-hdd
some new motherboards support EFI. After boot up, press F12 or F11 to enter the boot options menu. You can directly select the USB flash disk (the type of USB disk identified by inserting the USB disk in advance) or generic flash disk or removable device to start the computer without entering the BIOS interface
C. press F10 to save and exit BIOS, and the computer will restart automatically. If you successfully boot from the USB flash drive, the USB flash drive function menu will be displayed.

7. Press F1, F2, F12 or del at the same time, enter BIOS settings, start device settings, select USB device, click OK, and then press F10 to save. 1. First of all, you need to see what type of U-disk you start. There are generally four ways: CDROM mode, HDD Hard disk mode, zip driver mode and FDD floppy disk mode. CDROM mode needs mass proction, which is troublesome to make. Generally, HDD mode is commonly used. 2. Enter the BIOS, which is the picture above you. In the first boot devlce, select USB HDD (if your USB flash disk is not in HDD mode, you can select other USB flash disk modes you made), save and exit. 3. Restart the computer, there will be U disk boot mode, according to your needs, you can choose to enter PE or other modes. I hope it's useful for you. It's BIOS. HDD is the boot item of U disk. The old BIOS doesn't have it. It's in your BIOS.

8. When booting or restarting, press F2 to enter BIOS before entering windows. It's like a boot to move to the third one. Then set the option of "external boot" to "enable". Finally, press F5 to set the first startup item to "external device" (F5 up, F6 down). Press F10 to save. OK.

How to reload the system (first of all, prepare a system installation disk): restart the computer. When the words like "press * * to enter setup" appear on the screen, you should pay attention to what "* *" is, which means to press what key to enter the BIOS. First, set up the CD-ROM drive: 1. After the machine starts, first press del to enter the BIOS (notebook press F2 or see the motherboard instructions). 2. Select advanced BIOS features through the arrow keys on the keyboard. 3.

1. If you need to boot from the CD-ROM drive, set the first boot device to CD-ROM; DVD-ROM
2. If you need to boot from the U disk and other mobile media, set the first boot device to usb-fdd or usb-zip or usb-cdrom. (if you don't know which type of your mobile media is above, it is recommended that you set the first boot device, the second boot device and the third boot device to the above three types respectively, and you won't be wrong!). In particular, some Lenovo computers are quite special. Their mobile recognition is unified as removable device. When setting, you only need to set this as the first startup
