Please clarify:
- which OS?
- acer laptop: age? warranty?
- reformat: why? quick or full? using system OS or external media?
- do you have external copy of OS which you want to install?
- did you repartition?
- does BIOS properly identify all of your boot media (internal HDD, DVD, USB flash)?

The scenario is this. I was on the reformat thing and when I format the hdd it has a error pop up stating that the netbook is not compatible with gpt, because I boot the usb using an gpt not mbr using rufus. So I reformat my usb again and this time it's mbr after that I check again the cmos/bios utility in my surprise the "boot manager just vanished". In manay ways I tried to google every possible solutions and your channel give me a hint so I tried it out. So I use your way and when I go to cmos utility I can see my usb after I insert my usb 2 with OS it cannot be detected.

Sorry, I am pretty confused as to your situation. My small understanding is that UEFI does not use typically MBR if a modern EFI table exists. If device is repartitioned for MBR, it will use it - but all files will be gone. Since UEFI is determined by the maker, perhaps you need to go to Acer for more on this.

Would you be happy if you just 'refresh'?
