Can't boot from USB in Aspire E1-572-6870 in UEFI Mode.

I am trying to install Ubuntu 13.04 alongside Windows 8 in dual boot mode. For that I have created a 'UEFI enabled bootable Ubuntu 13.04 USB stick', but I cannot figure out how to boot with a bootable USB stick while in UEFI mode.


Ubuntu 13.04 supports Secure Boot, and can be easily installed in 'UEFI + Secure Boot' mode without any problem, if only it is possible to boot with a UEFI enabled bootable media. I have also tried booting with Secure Boot disabled, to no luck.

 

To run Ubuntu in UEFI Mode it should be installed in UEFI Mode (as far as I know of). A Legacy BIOS installation will not work in UEFI Mode (just as Windows 8 won't).

 

Bootable USB Stick however gets detected in 'Legacy Mode'.

 

So, how can I boot into my "Acer Aspire E1-572-6870" from a USB Stick in UEFI Mode.

PS: This device does not have any Optical Drive.

PS: The device came with Windows 8 pre-installed in UEFI Mode, and I believe it is not possible to change the Windows installation from UEFI to Legacy. Also, I don't want to get rid of Windows, but have it alongside Ubuntu.

    It is a bit more complicated but suspect the USB drive needs to have a GPT and be formatted FAT32. I thought Ubuntu only supported UEFI in the 64 bit version. Is that what you have or has it changed ?

     

    See http://msdn.microsoft.com/en-us/library/windows/hardware/gg463524.aspx

     

    BTW Windows 8 supports GPT in 32 bit mode.

    Converted USB stick to GPT Disk, and formatted the only partition in it to FAT32, then created a bootable Ubuntu 64bit USB stick. Yet, USB Stick is not visible in the Boot Device selection menu at start.

    Settings: UEFI and Secure Boot enabled.

    Hi, I am having the same problem with an E1-572-5420 and a bootable Windows7 USB, no matter what i put first in UEFI boot order the machine doesn't recognize it when booting.

    I would suggest trying your other USB ports. I've worked with devices that don't boot on USB 3.0 but do on the 2.0 and vice versa. Padgett is right, 32 bit Ubuntu OS is not capable of recognizing EFI systems.

    I have all the ports, both USB 3 and USB 2, but it doesn't works.

    My understanding is that the UEFI boot certificate library only contains two certificates, Acer's and Microsoft's. Unless the boot device is signed with one or the other, it won't show up as a UEFI selection.

     

    To boot "something else" you need to erase the library AND disable secure boot. This is not recommended for any ventless (W3 and W510) tablet because only Windows 8 has the Intel thermal management software.

    So, what are my options here?
    I think tampering with any BIOS/UEFI library will violate device warranty.

    I can disable UEFI/Secure Boot all together and switch to Legacy Mode, but then I will have to re-install Windows, which is acceptable. But, then again is it possible?

     

    When I boot into legacy mode, there is NO Operating System, no recovery option. There seems no option to switch my Windows Installation from UEFI to Legacy Mode. Is it possible to install a fresh Windows using recovery USB (NO CD/DVD Drive in laptop).

    Also can I make more than one recovery USB (I guess I can always 'dd' that, or replicate the USB using other software). I was asking this because I wanted to make a recovery USB for current temporary use and later make a final copy.
