Maximus VII Ranger bugged boot?

[TheOwner]

After i flash my motherboard to latest bios 3003 i have some problem if i want boot from usb or dvd. If i press F8 and select boot from usb/dvd sometimes system boot normal to windows and other time i open bios by doing this. Other problem is if i want boot from windows DVD, for expample windows vista, nothing happens. If i boot from Win7 DVD booting is succesfull because is here uefi loader. It seems i cant boot in leagacy mode from DVD. But if i use USB i can choose leagacy. My windows is instaled in leagacy mode and boot each time, there is no problem.

I dont understand this, after i flashed bios i set default settings, so there is no my mistake.

Do you have the same problem or just only me? Is there any solution? Thanks

You can try using Flashback and flashing the BIOS with a previous version.

I flashed back to BIOS 2902. Nothing happend, problem still the same. So i am again back to 3003. Only solution how boot in legacy from DVD is set boot order from DVD first, then legacy boot work fine. But i cant still select boot override or F8 during POST because only uefi appear. So it is bug, only I have this problem?

Problem solved. I had disabled Boot option #2. But i think boot override or F8 during post no matter about boot option.
