    Re: Problems with UEFI disabled.

    Is your grub> from your installer or after you have installed?

    It sound like you may not have a good download or good install.

    You can confirm that download is good:

    Grub is from the installer. I am still wondering if this is a video compatibility issue. That is why I ran that test. I dont know what the results of the test mean. I will try to install from USB.

    I ran the md5sum and they are fine. My DVD burn seems fine.

    Re: Problems with UEFI disabled.

    If you are getting grub from DVD or flash drive installer that is a UEFI boot. BIOS/CSM boots with new UEFI systems use syslinux.
    But if new UEFI system you probably want UEFI boot. But you should get grub menu as shown below. A few older UEFI systems will only boot with BIOS mode. But they may have fixes in a new UEFI/BIOS from vendor.
    Both screens shown here:
    Shows install with screen shots.

    Also shows Windows 8 screens

    Re: Problems with UEFI disabled.

    I have UEFI enabled. I have secure boot disabled.
    I shrunk my disk with the windows utility compmgmt.msc

    I am booting into the old style non gui black grub boot screen and editing the linux line. I have added nomodeset and the other 3 options you suggested.
    I have tried to boot from my internal DVD, external DVD and USB live.

    My Win !3 Install has a 400 MB Recovery Partition, 300 MB EFI System Partition, Win Partition, 450 GB soon to be Ubuntu partition and a 13 GB recover partition.
    No luck.

    Re: Problems with UEFI disabled.

    Are you using the 64 bit version? It is the only one with UEFI capability.

    Re: Problems with UEFI disabled.

    I think some others with Gateways have had issues but I do not know about AMD systems with AMD graphics.
    Is UEFI/BIOS most current version from Gateway?

    Re: Problems with UEFI disabled.

    I tried to find a location where i could obtain an updated BIOS. I was not able to find anything on the Gateway website or elsewhere. I opened the case and the MOBO is stamped with "Acer inc" "DAA75L aParker 1105-1 The BIOS states that it is version P11-A3 12/20/12. I would try the Acer site for a BIOS but the somewhere, I think on the boot screen the statement "only use a Gateway BIOS or warranty is voided" blah blah blah

    I managed to stumble across the support website. It seems there are quite a few BIOSs available and even dedicated linux BIOS. Very cool.

    Re: Problems with UEFI disabled.

    There really should not be a different UEFI/BIOS for Linux. UEFI is a standard that both Windows & Linux should comply with and work without issue.
    It sounds like that Gateway has a Windows only UEFI with internal changes that do not comply with UEFI standards. That they have different versions may mean they did not provide enough nvram for full correct UEFI for both.

    Some Samsungs had major issues and it turned out that if their UEFI nvram got over 50% full system became a brick. Linux had to create work around to make sure nvram was not too full. Had to do more with not clearing nvram memory when released. Originally blamed on Linux but found it would happen in Windows eventually.
