after having spent many hours to understand windows 8 and UEFI BIOS behavior, to be
able to start the machine from any "FAT32/MBR boot device" using "legacy bios" (secure boot disabled),
now I have a "little" problem with my new Acer V5-571G. This is the "story":
- I made a Windows driver and BIOS update using acer "live updater" software from to BIOS v.2.11 (that is not available in the acer support website...)
- In this situation pressing (and holding) the F2 key before the power on button gave me access to BIOS setup screen
- At this point in no way I was able to start any boot device different from internal HDD.
- So, I set up the bios admin password, enabled boot menu (F12 key), and enabled "Legacy BIOS" (this disable also "Secure Boot").
- After a restart, also in this situation, no boot device was able to start...
- But at this point the problem is that F2 key to access setup BIOS page doesn't work, so after searching a solution from internet (using another PC because in non uefi mode Windows 8 doesn't start) I gained Windows access and UEFI mode by pressing and holding the power on button for 2 minutes... however from this moment F2 key doesn't work also in this UEFI mode.
- with uefi enabled, the only way I can access the BIOS setup screen is to select it from Windows 8 configuration page.
- In non uefi mode (legacy bios) I can start from a boot device like the Windows 8 recovery pendrive or dvd (I don't know why now works, I tried different bios configuration, lastly setting up also the user password)
- to return to uefi mode I have to press for two min the power button (!!)
The problem is that if the internal HDD will be damaged, I will not be able access to BIOS setup using a specific key (such as F2).
Do you know if there is a way to solve this problem? Thank you.
