    That is normal for most machines that are even reasonably modern. Legacy boot hasn't been used since the Windows 7 days, and is inherently less secure than the current system. What makes you think you need to use legacy?

    Are you serious mate...!!! In UEFI MODE it can't even see the usb boot disk...!!!! UEFI MODE is for hd bigger size... Meanwhile legacy is for less than 4 TB disks and for less partitions.... I needed help but I see that I'm the one helping for something lower than problem.. hhhh

    That's actually not quite right. Legacy mode requires MBR format drives, which have a single boot block that can be overwritten by pretty much any software, hence the ability to install root kits on those devices. You are getting it confused with the file system, where FAT32 only supports partitions of 4TB and individual files of 4GB. UEFI use GPT format drives and has a EFI partition that holds the boot info. Secure boot is built into the BIOS which disallows booting from an unknown file, so no root kits. In order to boot from a USB device on an Acer UEFI system you have to first enable the boot menu in the BIOS, it is disabled by default, then use that boot menu to choose which boot environment to use. Typically modern Windows systems use NTFS for the file system which allows for drive sizes up to 9.4XB (9,400,000,000 TB) and individual files of 256TB, so that does deal with large disks more easily.

    So, your question was actually about how to boot from a USB drive? If so, first enable the boot menu in the BIOS, then use F12 at boot to get a menu of all bootable environments. The USB drive should show up there, unless it's not UEFI for some reason.

    Mate thanks for your effort anyway… but my problem is much more complicated than u think.... Easy to say .. enable your boot menu in the bios or change to legacy or efi... When the boot menu or other options are off and can't be changed no mater what I do .... 😵😵😵.… 🤔🤔🤔

    Do a Boot enable then reboot while tapping the F12 key.

    For the Veriton N4670GT models you should see something like this in the BIOS:

    Just change the Boot Menu option from disabled to enabled, then use F12 at boot to get the menu showing all valid boot environments.
