Ubuntu does not show in Boot Menu

[Kenny48]

Today I attempted to install Ubuntu 12.04 on my new Z570. I used an installation disk. Ubuntu worked fine, from the disk. So I installed it alongside Windows 7 as a dual boot. However, when I go to the boot menu, I only have a choice between the hard disk ( no partitions ), the CDDVD drive, and some Lan PCI that sounds like an ethernet connection. So what is the problem, and is there a way to fix it. If nothing else I will delete windows and install Ubuntu on the entire disk. It's just that I do like to play some games on Windows and would like to keep it. Otherwise I'm a confirmed Ubuntu user ( six years ). If anyone knows a fix for this problem, I would appreciate hearing from you!

Hello and welcome,

I wouldn't expect Ubuntu to show up in the  boot menu - if you're referring to the boot-time BIOS boot menu.

In all the dual-boot Windows and Linux setups I've done (I've lost count...) on a single drive, that drive is what shows up in the BIOS boot menu.  Once the drive is booted, up comes the grub menu that lets you select between Windows and Linux.

What you describe is what I'd call the BIOS boot menu.  It lists devices (HD, USB, network...) not installed operating systems.

What happens when you select the hard drive as the boot device?  If you don't get grub's menu, something in the install got sideways.

Maybe I'm misunderstanding what you are doing.

[edit] Is this a UEFI mode install?  That's a different beast.

I agree with you.  This does not sound like a boot menu.  However when I turn on the computer and hit the escape button. First it tells me if I want the multi boot menu to press F12 which gives me that menu.   It gives the three choices I mentioned.  If I choose the Hard Drive and hit enter.  It goes straight to Windows.  The others just give me a blank screen.  The second one is the Hard Drive, because when I have a disk in the bay, it opens the disk if I click on that one.

I expected to see something else, as I have a dual boot on my Acer Netbook and it gives me the choice of XP or Ubuntu likeise both in safe mode, or regular mode.  It looks totally different than this.  This looks like a hardware menu.

Yep, F12 gets you the hardware boot menu.  That's OK, but with a dual-boot install, you will just select the HD anyway.  Same as just letting it boot the default device.

For some reason, the Ubuntu install didn't put grub in the MBR, it seems. Did you select where to put grub during the install?  MBR or Ubuntu install's boot sector?  If the later, you will probably need to use a tool like EasyBCD to add Ubuntu to the Windows boot manager's menu.

Or re-run the install and make sure grub goes into the MBR - if that's what you want.

Well I googled some questions, and came up with a solution.  It's called Boot-Repair I installed it, ran it and now I get the grub menu!  All is well in Ubuntu land!

Thanks,
