After switching from UEFI to Legacy there's nothing but a black screen and beeping function keys. There's no Acer logo as well.
I tried to find CLRP1 jumper on my motherboard to reset BIOS, but I can't. Also BIOS CMOS battery can't be removed.
Can anyone help me to reset BIOS?

    Press and hold the power button for 5-10 seconds or till the machine completely shuts off. Then turn it back on again and ***immediately*** start tapping the F2 key. Jack E/NJ

    If you temporarily remove your hard drive, you should be able to regain access to the BIOS.  After you regain access to the BIOS, you can load the BIOS defaults (F9) and then save/exit (F10).   Now you can re-install HDD, and everything should be back to normal.

    In the video below, it shows you how to remove your HDD.  (you don't have to remove the bracket).

    If you are trying to boot a legacy MBR drive, don't forget to enable the F12 boot menu so you can boot the legacy drive if that's what you want to do.
