    We need to know what's happening with your system. How it boots and in what mode.
    It may be a UEFI machine but booting in bios mode. Can you enter your bios and tell us what booting options are there please and what are currently set?
    Also if you could boot into the Ubuntu cd/usb and select "try Ubuntu" then when the desktop loads open a terminal and run
    Code:
    sudo fdisk -l
    and post the output here please.
    ubuntu@ubuntu:~$ sudo fdisk -l

    Thanks. When you boot the Ubuntu live usb I presume you get a black screen with a couple of lines of type at top left rather than the purple screen with the little man at the bottom?

    Re: Windows 7 now will not boot and Ubuntu failed

    Version should not make any difference.
    You have a BIOS boot Windows with the standard 100MB Windows hidden boot partition sda2 and main install in sda3.

    Use Windows to shrink the main Windows install to make unallocated space for Ubuntu. Do not create partitions with Windows as it may want to convert to dynamic partitions from basic. Reboot into Windows so it can run chkdsk and make repairs for its new size.

    I usually partition in advance with gparted but you can do it during install. You will have to create sda4 as an extended partition including all the unallocated space. Then inside the extended you can create an unlimited number of logical partitions. All your new partitions will be logical.

    For the Total space you want for Ubuntu:
    Ubuntu's standard install is just / (root) & swap, but it is better to add another partition for /home if allocating over 30GB.:

    for gpt(GUID) or MBR(msdos) partitioning
    Ubuntu partitions - smaller root only where hard drive space is limited.
    If total space less than about 30GB just use / not separate /home or standard install.
    1. 10-25 GB Mountpoint / primary or logical beginning ext4(or ext3)
    2. all but 2 GB Mountpoint /home logical beginning ext4(or ext3)
    3. 2 GB Mountpoint swap logical

    Depending on how much memory you have you may not absolutely need swap but having some is still recommended. I do not hibernate (boots fast enough for me) but if hibernating then you need swap equal to RAM in GiB not GB. And if dual booting with windows a shared NTFS partition is also recommended. But you usually cannot create that as part of the install, just leave some space. Or partition in advance (recommended).
    One advantage of partitioning in advance is that the installer will use the swap space to speed up the install. Thanks Herman for the tip.

    Installer has not really changed, so you can install with 13.04 and screens will be almost the same in these examples.
    Install with separate /home from aysiu

    Install 12.04.1 with screenshots of Unity, gnome3, & gnome fallback - Not everything is necessary, but shows how to do many things

    Re: Windows 7 now will not boot and Ubuntu failed

    Thanks. See what Oldfred has to say but Ubuntu live usb is definitely booting in EFI mode. With your system it needs to boot in bios mode. To change that there will be a setting in your computer's bios.
    In this mode grub_efi cannot be installed. It should be installing grub-pc.

    And if dual booting with windows a shared NTFS partition is also recommended. But you usually cannot create that as part of the install, just leave some space. Or partition in advance (recommended). This I do not understand completely and would mean I do need to partition in advance instead of during install. ? I don't understand how to just "leave some space." Thanks for all the help. I'm not gonna give up just yet.

    Re: Windows 7 now will not boot and Ubuntu failed

    Give up? Certainly not!
    A shared partition is a matter of choice only.
    Leaving space is accomplished in the "something else" option partitioning screen. You just don't use all of the available space - you make a swap partition and a root (/) partition but leave some space unallocated. Or create an NTFS partition in that unallocated space if you so desire.

    Anyway, you need to get the Ubuntu live usb to boot in bios mode first or you won't be installing or partitioning anything.
    Any news on your bios settings in that regard?
