Recently, when a friend pressed F2 on the keyboard during boot, the computer could not identify the boot hardware, prompting IPV4 ********, IPV6 ********, I don't know how to solve this problem. The following describes how to solve the failure of hardware startup by F2 in Win7.

You can perform the following operations on a desktop:

1. first, restart the computer. Then, Press F1 on the keyboard to enter the bios settings menu of the computer. Then, use the arrow keys on the keyboard to perform operations and select Startup, then, click Enter.



2. In the window that appears, find the Boot Priority option and change the setting status to Legacy First.



A laptop can perform the following operations:

1. first, restart the computer, press F2 or F1 on the keyboard to enter the bios settings menu, and then enter BOOT-Boot mode in sequence, and then change its status to Legacy first.



2. After setting, press F10 to save the setting.
