So I downloaded Ubuntu onto its own partition and want to dual boot from it. With windows 7.
My issue is that while I have all of the files on the hardrive I am not sure how to start the installation. I have no disk. because it was downloaded.

Thanks for takign the time to answer! -Z

Can you burn the ISO to a CD, or DVD, or flash drive? After that, just boot into it. The installer will guide you through the rest.

Where did you download your Ubuntu OS? It should download as a single ISO file.

And once you burn the ISO into a CD, pop it into the optical drive and reboot. Enter the BIOS and set the default boot drive to your optical drive. Then exit the BIOS and that should boot using your Ubuntu CD.

You mean this one?. It's only 30 MB. The installer will download packages as it needs them from the Internet so I recommend having an Ethernet connection.

It shouldn't be 22GB unless you're downloading a bunch of files. Ubuntu only takes up a few GB of storage space after install.

Even that is only a 950MB ISO file. A bit big for a CD so you'll have to use a DVD or a flash drive. No where near 22GB though. Also, don't extract the ISO. Burn it as is. If you got the mini version that I posted up, you can burn it to a CD.

This is my hardrive and all the files on it. The one that says "massive folder form drive c" contains a iso archive that is like 23,456,880KB and is causing the big chunk of space. I put it there to leave space on my SSD. Now I am not sure what to do but that is what is on my hardrive. without that file it is probably about the size you said.

Burn the ubuntu-14.04-desktop-amd64 ISO into a DVD or flash drive. Don't extract it to your hard drive. Burn that one iso file as is to a DVD or flash drive. Then restart your computer and boot into the DVD or flash drive.

Do you have a disk burning software?

What happens when you tell it to boot into the DVD drive? Usually, upon POST, it should ask if you want to boot from a CD/DVD by hitting a key. You can also try boot menu upon POST. It's one of the F keys on your keyboard. To be sure you are not booting from the hard drive, you can unhook your hard drive so it cannot boot using it.

If all went well, then perhaps you didn't burn the image properly. Can you show me the contents of the CD or DVD?

I misunderstood something earlier. i found a webpage, and figured out i needed to unpack the zip folder onto the disk and then boot. i was trying to boot to a disk with just that iso file. i am extracting now and i will try again. i get into bios and select to boot to that drive but then it boots to windows, probably because nothing was in that but that iso archive. now i am just getting ready for work while winzip does its thing. hopefully i can get ubuntu started installing while im off at work

What option did you pick when you used ImgBurn to write the ISO to the CD? Something like: "Write image file to disc"? And then you selected the ISO file? Got a screenshot of the contents of the CD?

That ubuntu-14.04-desktop-amd64 file should NOT be in there, but I don't think it matters. Take a quick read at this.

I think this may help: http://unetbootin.sourceforge.net

I probably should've suggested it sooner but it skipped my mind. I am so sorry.
