acer 是F2 ? 我开机的时候下面有写小小个的F2什么的
开机按F2 是进入bios 里面
开机按F12 是进入boot 选项
如果开机按F12 没有反应的话,有可能是F12 功能被disable掉了
我从acer的网站抄下来:
Enabling the F12 function:
1) Power on the system. As soon as the first logo screen appears, immediately press the F2 key to enter the BIOS.
2) Press the right arrow key to select Main.
3) Use the arrow keys to navigate to F12 Boot Menu, and press ENTER.
4) Select Enabled, and press ENTER.
5) Press the F10 key to save changes and restart the system.
If the boot menu feature is not available in the BIOS setup menu, then the option is not available on your system.
