    Help with Windows 8 Install

    I hate Windows 8. I want to install and try Ubuntu. I have followed all the directions I could find on this forum. I have created a separate partition (100G) and have followed all the directions to disable SecureBoot in BIOS. My computer is a Lenovo A10 with Windows 8 pre installed.

    I created a LiveUSB flash drive and when I reboot into BIOS with the USB, the options I get are to try Ubuntu, which I would like, or install it.


    The problem: That's as far as it goes. None of the options work. I keep getting an invalid kernel image message no matter what I try.


    I have a rooted SGS3 with CleanROM and a rooted Acer A500 with LightSpeed so I have a very introductory understanding of flashing some things.


    I would like to get this to work but so far it seems to be proving more difficult than it's worth.


    All help greatly appreciated!

    Try thi tutorial to make a bootable USB Disk or SD Card. http://www.psychocats.net/ubuntu/usb
    Also, be sure your Ubuntu ISO is not corrupted.

    Some follow up.

    I am using a RockFish USB formatted in Fat32 and already used Unetbootin to make the USB.

    I see that your laptop is fairly new. I'm not sure if it is supported fully in ubuntu what version is your ISO? I hope some experts will shed light in this matter.

    Can you boot from the USB on another computer?
    Maybe try a different distro just to test?

    I am using the version from the Ubuntu website they say to use for Windows 8.

    I can try on an older laptop and see if that works.

    Thanks

    Did you download the 64 bit version? That is the only version with UEFI support. And how you boot installer UEFI or BIOS is how it will install. To dual boot with Windows you have to install in UEFI mode, not BIOS. But some systems only let you install in BIOS mode. For those systems you then can use Boot-Repair to convert to UEFI mode.

    You will need to use the 64 bit version of 12.10 or 12.04.2 and from the UEFI menu boot the flash drive in UEFI mode. That way it will install in UEFI mode.
    Systems need quick boot or fast boot turned off in UEFI settings. Vital for some systems.
    Best to backup efi partition and Windows partition first.
    Use Windows Disk Tools to shrink Windows main partition, but not to create any new partitions, if installing on same drive.

    As of 12.04.2, it is possible to install on UEFI systems with Secure Boot enabled (using signed versions of Shim, GRUB, and the Linux kernel). This is only currently set up for Ubuntu (desktop, alternate, and server) and Edubuntu images due to pressures of time; we expect to enable it across the entire Ubuntu family for 12.04.3. Details:

    Ok I'll give it another try. right now the computer has secure boot off and is set in Legacy mode.

    So, since I'm using the 64 bit 12.10 you are saying I should turn EFI back on instead of Legacy?

    A few systems only will boot in BIOS/CSM/Legacy mode, but most should boot in UEFI mode. Often you do have to have secure boot off, but with Ubuntu that should not be a requirement.

    Update:

    I tried the above with EFI re-instated. I received the following error messages:

    error: premature end of file /casper/vmlinuz.efi.signed.
    error: you need to load the kernel first


    Any additional ideas?

    Thanks
