Hello. Sorry for my bad English.
I have HP Pro 3500 Series MT wth Windows 7 x64 Ultimate installed on it. Motherboard is Foxconn 2ABF (in AIDA64). And I can't enter BIOS. And before you started to send me links for "same forum topics" I would like to tell you - I've read them all. F10, ESC and F2 REALLY don't work.
Here is the story. 2 years ago I installed this OS on my PC. I don't remember anything about entering bios. 1 mounth ago I decided to upgrade my OS to Windows 10. And it was successfull.
But then I needed to turn on Virtualisation in BIOS (I had to do it for VirtualBox) and change some another settings. But after restarting my PC I can't enter BIOS.
I tryed to enter it from special Win8-10 reboot with diagnostic. But the menu doesn't contain necessary item. After that I tried:
- Pushing buttons: F1, F2, F4, F8, F9, F10, F11, F12, DELETE, ESC, CTRL+ESC. It doesn't work. The screen was black with blinking cursor, then VERY fast it shows me screen with hardware info and "press ESC key for startup menu". But after pressing ESC (or another buttons) I enter "choose windows" screen. I tried to push buttons very fast in all moments of restarting PC.
- Getting battery out of motherboard and waiting 1 min. After that I can see hardware info, but I have only one menu item - "Press F1 to Boot". And other buttons don't work. After pushing F1 OS starts.
- Manipulations with jumpers also don't work.
- I tried to switch off HDD, DVD and Ethernet cables. But I receive only "can't boot" screen and buttons don't work.
- I tried to flash the last BIOS firmware. Nothing happened.
- I can boot from USB of DVD with OS installation, but that is all what I can.
- I even tried to reinstall Win10 and back to Win7. Win7 is fine now. But again nothing happened.
- All HP utilities don't help.
So, does anybody know how to enter bios? Because the last solution is changing motheboard...
