I've installed Ubuntu 12.04 using a Live CD to a new Gateway computer with Windows 7. I used "Install Alongside Windows" option. But on restart there was no boot menu. It only starts into Windows. I looked at partitions using GParted (with Live CD) and it shows my new Ext 4 partition for Ubuntu as follows:

sda4  Extended,
sda5  Ext 4,
sda6  linux-swap

But there is no / Mount Point listed for the sda5 partition. I did try Boot-Repair but it did nothing. So I've got 2 problems: no GRUB menu and no / Mount Point for my ext 4 partition.

I'm so exasperated. Do I have to edit the fstab file to create a / mount point? (And that prospect really scares me.) And if I do, could someone give me step by step instructions.

In order to avoid this detailed and scary stuff in the Terminal (which I really do not know very much about), I deleted the ubuntu partitions and started all over installing 12.04 again. But I'm left in the exact same situation now.

Thanks for any help you all can provide. Is there an easy way out of this?

Are you choosing to install GRUB? If not, I think Windows has an option to display OS'es on boot but I don't know if Linux is supported. –  Corey Whitaker Jul 10 '12 at 1:16
I was not paying attention during the installation of Ubuntu. Does it give me the option of installing GRUB? Thought that was automatic. However I did try to use EasyBCD to add Ubuntu to the Windows boot loader. But when I did that it brought me to GRUB4DOS (BASH line entry). And I had no idea what to type into the grub> prompt. (I did try typing in "boot" and got back an Error 8: Kernel must be loaded before booting.) –  Liz Kaiser Jul 10 '12 at 5:04
GRUB is normally automatically installed but I do believe it gives you the option with the default being to install it. I'm not experienced editing the GRUB files, but you can look here for assistance doing that. Also, if the files referenced here don't exist, then I think it's safe to assume that GRUB is not installed. Please look here - help.ubuntu.com/community/Grub2#Configuring_GRUB_2 And more specifically here for more information on how to edit GRUB to do what you need it to - help.ubuntu.com/community/Grub2/Setup#Configuring_GRUB_2 –  Corey Whitaker Jul 10 '12 at 5:07
One more thing to add: When I tried to use Boot-Repair I got back this message "boot of PC is in EFI mode. May want to retry after changing it to BIOS-legacy mode." I did not know how to change it to BIOS-legacy mode. –  Liz Kaiser Jul 10 '12 at 6:03
Please run Boot-Repair, update it, click "Recommended repair" and indicate the URL that will appear. This will give us valuable informations to help you. –  LovinBuntu Jul 10 '12 at 17:12
