预装Ubuntu系统的惠普笔记本无法进入BIOS以实现USB启动的问题求助

Hey there! Let me share some practical fixes I’ve used for similar HP + Ubuntu issues—let’s get you into BIOS to boot from that USB:

Timing is everything with the boot keys
HP laptops usually let you access BIOS/boot menu when the HP logo first pops up. Shut down your laptop completely (even unplug the power and remove the battery if it’s removable), then power it back on. As soon as you see the logo, start pressing ESC or F10 rapidly—don’t just press once, keep tapping until the BIOS menu shows up. Sometimes Ubuntu boots fast, so you might miss the window if you wait too long.
Boot straight to BIOS from Ubuntu itself
If the hardware keys aren’t working, try this terminal trick. Open a terminal (press Ctrl+Alt+T) and run this command:
sudo systemctl reboot --firmware-setup
This command tells Ubuntu to restart directly into your laptop’s firmware settings (BIOS), and it works reliably on most modern HP machines running Linux.
Turn off Fast Boot
Fast Boot can skip the BIOS trigger window. In Ubuntu, go to Settings > Power and check if there’s a "Fast Boot" option—disable it if you find it. Then restart your laptop and try the ESC/F10 keys again.
Try alternative boot keys
While HP’s standard is ESC (for boot menu) and F10 (for BIOS), some models use F2, F9, or Delete. Give these a shot too, tapping them immediately after turning on the laptop.
