Steps for lenovo Lenovo or ThinkPad to start USB flash drive or CD:

Step 1: Enable quick start menu mode:

1, press the F 12 key repeatedly when the Lenovo self-test screen is displayed (some ultrabook models may be the combination key of "Fn+F 12").

2. The startup menu will be displayed. In the displayed startup menu, move the cursor to the item selected in the red box in the figure, and then press Enter to enter the U disk.

3. Some computers may display different shortcut start menus, as shown in the figure below. The USB flash drive displayed in it is not the name of USB flash drive, but USB-HDD, and this is also a USB flash drive, and it also shows the optical drive item. If you want to start the computer with the system CD, you can select the CD-ROM drive item.

Step 2: Boot USB flash drive or CD from BIOS in traditional mode:

4. When the "LENOVO" self-test screen is displayed at the boot, immediately press the Del key to enter the BIOS setup main interface. Because the display time of the self-test screen is short, you can press the Del key continuously as soon as you turn it on. Some Lenovo computers may press F2 to enter the BIOS.

5. After entering the BIOS main interface, the main item will be displayed by default. First move the cursor to the security item, and then use the up and down arrow keys to move the cursor to "safe startup", which means "safe startup settings" in Chinese. If you want to start a USB flash drive or CD in the traditional way, you must set this item and press Enter to enter.

6. After entering the subpage, select Safe Start, press enter to open a small window, select Disable, and then press enter to confirm.

7. Then select the startup item. First, choose UEFI/Legacy Boot, which means "new UEFI and traditional boot mode" in Chinese. UEFI only is now displayed. We have to choose compatible mode, that is, compatible with the traditional BIOS mode, so enter, choose both, and enter to confirm.

8. At this point, UEFI/ legacy boot priority items will be added. We select this project, enter, and select Legacy First in the small window that opens, which means that the traditional startup mode should be listed first. Press enter to confirm.

9. After the above settings are completed, start setting the following startup items. Still starting, select the boot item and press Enter to enter.

Tip: By the way, if some shortcut start menu keys F 12 can't be started and there is no response when pressed, it is because the function keys F 12 here are not turned on. If it is disabled here, the shortcut key F 12 will definitely not work, so it should be set to enable, so you can start the menu with the shortcut key F 12.

10, after entering the startup options interface, select USB HDD SanDisk Cruzer Edge, which is a USB flash drive startup item. First move the cursor to this item, and then use the+/-key to move this item to the top, so that it is arranged at 1. This is the first startup item, press enter to confirm.

1 1, due to the different versions and models of computer BIOS, the displayed items are different, as shown in the following figure.

If you want to boot from a USB flash drive, just select USB-HDD.

Select "ATAPI CD0 HL-DT-ST DVDRAM GU70M" if you want to boot from CD.

If you want to return to the hard disk to boot, please select "atahdd0hgst ht3541kloc-0/0a9e600".

Just use the+/-key to move them to the top 1 position. Press enter to confirm.

12, so the traditional BIOS setup is completed. Enter the restart item, select Exit to save the change item and exit.

Another method is to directly press the F 10 key, which has the same function, and all of them are saved and exited. After restarting the computer, you can enter the USB flash drive or CD-ROM loading system.

Third, add a USB flash drive or CD-ROM startup method:

13, press the Del key when starting the machine. Some versions of the computer may enter the BIOS through F2 key. After entering, change the default value of operating system optimization to be disabled at the last restart. Enter the startup item again, first change UEFI/Legacy Boot to Legacy, and then press F 10 to save. After exiting, you can enter the USB flash drive startup disk.

14 finally, a common problem in installing a system is the problem of hard disk mode. Because some old systems, including a large part of XP systems, don't have SATA drivers in their systems, when installing systems with this old ghost or PE (old PE doesn't have SATA drivers, most new PEs do), there will be a phenomenon that hard disks can't be found, and the general problem lies in the hard disk mode setting in BIOS.

To set the hard disk mode correctly, first enter the configuration item and change its mode from AHCI to compatible, so that the hard disk can be displayed in PE. After installing the system, change it back to AHCI. Why did you change it back? Because AHCI hard disk mode has better performance and faster speed.
