Lenovo bios cannot boot from USB disk

php editor Youzi will introduce to you the problem that Lenovo computer bios cannot start the U disk. When using Lenovo computers, we sometimes encounter situations where it cannot be booted through a USB flash drive, which brings inconvenience to our work and life. But, don’t worry, there are some simple things we can do to fix this problem. Next, we will explain in detail the reasons why Lenovo computer bios cannot boot the USB flash drive and the solutions. Let’s take a look!

1: Generally, when you turn on a Lenovo machine, you press F12 to enter the bios. When entering the bios, we use the cursor to move to the Security option, which means security. Then use the arrow keys to move the cursor to the Security Boot option, which means safe boot. Then press the Enter key on your keyboard.

2: Then select the Secure Boot option, press the Enter key on the keyboard, then select Disabled to close this item, and press the Enter key on the keyboard

3: Then select the Startup option again, first select the UEFI/Legacy Boot option, which means the new UEFI and traditional startup methods. Now it shows the UEFI Only single UEFI mode. We At this moment, select the compatibility mode, which means it is compatible with the traditional BIOS mode, so press Enter to enter, select the Both item, and press the Enter key on the keyboard to confirm.

4: Then select the UEFI/Legacy Boot Priority option to enter, then press Enter to select the Legacy First option, which means that the traditional boot mode is listed first, and then press the keyboard Enter key. Confirm

First, restart the computer and press the F12 key to enter the startup options. Then, select the boot device in the BOOT option and press the Enter key to confirm the selection. Please note that some computers may have the F12 key disabled, so you need to enable it in the BIOS settings. After making sure the F12 key is set to enabled, save the settings and restart the computer.

#After setting the startup item, select the U disk startup item, usually USB HDD SanDisk Cruzer Edge. Then use your keyboard's plus and minus keys to move the option to the top and press Enter to confirm. Please note that depending on the BIOS version and model of your computer, the options displayed may be different. If you want to boot from a USB flash drive, select the USB-HDD option. If you want to boot from a disc, select the ATAPI CD0 HL-DT-ST DVDRAM GU70M option. If you want to return to hard disk booting, select the ATA HDD0 HGST HT3541010A9E600 option. Again, use the plus and minus keys to move them to the top and press Enter to confirm.

#7: Then press F10 to save and exit. Restart the computer to enter the U disk or CD to install the system.

In addition, some additional information needs to be added. On some computers, you press the DEL key to enter the BIOS, while on others you press the F12 key. After entering the BIOS, find the "Restart" option and change its "OS Optimized Defaults" (that is, the default settings for operating system optimization) to "Disabled" to turn off this function. Next, enter the "Startup" option, set "UEFI/Legacy Boot" to "Legacy First", and then press the F10 key to save the settings. After exiting the BIOS, you can use the USB boot disk to start the computer.

The problem is the hard disk mode, because some older systems, including a large part of XP systems, do not have SATA drives in their systems, so they are using an old-fashioned Ghost or PE When installing the system (old PEs do not come with SATA drivers, and most new PEs come with SATA drivers), the hard disk will not be found. The general problem is that the hard disk mode setting in the BIOS is incorrect. To correctly set the hard disk mode, first enter the Configuration item and change its mode from AHCI to Compatible (compatibility mode), so that the hard disk can be displayed in PE. After installing the system, change back to AHCI. Why should you change back? Because AHCI hard disk mode has better performance and faster speed.

I hope my answer is useful to you!
