Hello.
I have problem with ES1-533, cant change boot mode to Legacy. Updated BIOS to newest and boot mode is grayed out(UEFI), before with older BIOS version this option was active but only variant was UEFI. I can change secure boot enabled/disabled. Is there any way to enable legacy mode?
Other strange thing is i cant boot from USB flash drive. In boot menu(F12) only option is Windows Boot Manager...

I have also Aspire ES1-311(can change UEFI/Legacy no problem) and tested with it, also cant boot USB if boot mode is UEFI(wont list it in boot menu), in Legacy mode it boot fine from USB. USB flash drive should be ok, boot in UEFI mode with other PCs.

    Some notebook models are no longer allowing you to switch to legacy mode! Probably your bios (which is actually called uefi) is already in the uefi class III version, which no longer allows the image of the legacy mode! Intel itself has already said that by 2020, all of its devices will only support UEFI!
    For the pendrive to work in uefi mode, go to the cmd as administrator and type: diskpart, list disk, sel disk x, clean, convert gpt (single that works in uefi mode), create partition primary , format fs = fat32 quick and assign!

    Thank you.
    Yes looks like its only UEFI device(i searched little bit before i made this topic and some people said they can change to legacy, probably however different laptop models etc).
    I probably will use wrong word "BIOS" long time, old habits die hard :)
    I downloaded newer Win10 iso and used different flash drive, now boots from it.

    Thankfully you were able to boot from the pendrive!

    Only if this can help,  I just bought a laptop Acer 3 yesterday, and was didoriented not to discover a traditional Bios.  But I actived the boot to F 12. Having already an usb key, formated Fat32, and Mint Cinnamon 19, installed with ''LinuxLive usb Creator'' (easy to find with Google), it worked like a charm. Already installed in dual boot...I don't need to go again in the Bios. Insert the USB, start the PC and press F12. And they ask you the choose on what we want to boot. I tried with other Linux distributions, and works very fine. I hope it will work for you to.

    Its got to do with your boot HDD mode as its in the 'uefi' mode GUID partition table (GPT), the only way around this would be to reformat the drive with MBR mode and reinstall the OS using a boot option (cdrom or flash drive) that does not have a (uefi) suffix and its in MBR. Also consider what egydiocoelho has said. But, I don't know why you would want to install Win=7 on your main drive unless you completely get rid of the GUID partition table (GPT) and Win-10 and convert it to MBR? Also consider installing Win-7 on an external drive and having a dual boot mode type system like a slave drive
