Installing ubuntu: won't boot from ubuntu install media...

Hi there,

I see, that you run into the problem with installing operating system. This is known error and solution for it is very simple. I suggest you, that you read this thread where is everything explained in details and you will know everything how to solve your question. Link for the topic is here: http://askubuntu.com/questions/133332/missing-operating-system-after-installing-ubuntu-12-04-from-a-cd-on-a-macbook It's explained for macbook pro but is the same for other systems.

Btw, you have probably some issues with your usb stick, try to copy your files again on it.

If this helps you solve your question, please mark thread as solved.

Regards,
Miha

Make sure you MD5 test the ISO so that you know it is complete and consistant.

Thanks everybody.

I downloaded UNetbootin, went thru the steps, everything seemed to work OK. Told me it was finished what it was doing with the ubuntu file & my USB stik, & that I should reboot now.

I started to reboot. I went to re-boot menu. I chose 'boot from USB' (only one inserted.)
Got UNetbootin dialogue box, saying it would boot in 10 seconds.
THEN got ERROR MESSAGE: "Invalid or corrupt kernel image"

I re-started the computer, & opened the USB stik that UNetbootin was supposed to set up as my ubuntu operating system stik.

It was an empty stick when I put it in. It's now got all these system-like files, apparently from whatever UNetbootin / ubuntu did with it.

But I notice almost everything on it displays its "Size" as "0 KB" (....??)

What now?
Thanks again

Hello ,

Did you open Unetbootin as Administrator ?

or

maybe a usb stick (hardware) problem ?

Please download again the .iso image from here : http://releases.ubuntu.com/12.04/

and do again the procedure with one difference : 1st delete - format the usb to Fat32 filesystem.

Also at unetbootin's menu click the first option "Default"

Thanks

Hi NIck
Yes, I'm Administrator on my computer: there is no other user.

And I did definitely re-format a blank USB stik in advance as Fat32.

Do you mean download the Ubuntu system all over again? To a blank USB stick?

What about all these mountains of system files that Unetbootin seems to have put on the stick? Are they supposed to be there? In addition to the Ubuntu op system file?

I'll try this again & let you know if it works.
Thanks a lot

I meant to download the .iso again. Maybe the one you downloaded is corrupted.

I gave you the Official site : http://releases.ubuntu.com/12.04/

Use this .iso image and do the procedure again , with Unetbootin. Yes it needs a blank Usb stick (at least 2GB) and FAT32 filesystem.

Good Luck !

The unetbootin system transfers the relevant files from the ISO to the USB and makes it bootable.

Thanks for your replies. Maybe I should back up a bit:

I'm trying to put it onto a USB stick BECAUSE

[Pardon message error just above]
 Thanks for your replies. Maybe I should back up a bit:

Maybe the question is DO I NEED TO PUT UBUNTU ON REMOVABLE STORAGE AT ALL?
I'm trying to put the op system on a USB stick BECAUSE instructions seem to be telling me to do that: to put it on a USB stick or on a CD.

Am I wrong in thinking that's necessary? I'd be perfectly happy to download it right to the hard drive. That's what the computer seems to do automatically, anyway: when I go to the site Nick just pointed out (in his preceding message), and click the type of version I'm choosing, it starts downloading directly to the "Downloads" folder on my hard drive. It can stay there, as far as I'm concerned.

Is that OK? But then to boot . . . ?

I'd be glad to REPLACE the Windows7 op system (which I hate passionately) that came with the computer; but don't want to take that step until I've got Ubuntu running, see that it works, that I like it, etc.

I'd also like to keep Windows7 around as back-up, in case of some program that I can't run without it, etc.

So this means the question here may be DO I NEED TO PUT IT ON REMOVABLE STORAGE AT ALL?
If I DON'T put it on a stick or CD,
   guess I need to to store it in a DIFFERENT hard drive than Windows, and
    need to choose that alternate hard drive in the boot menu . . . right?

That's possible, right?
Thanks again

Do you want to install Ubuntu in you PC , in you system , in your Hard Drive Disk or you want to have Ubuntu in the Usb stick and boot from there every-time you connect the usb stick your PC ?

Clarify that , and we will tell you how you can do this.

Thanks

Yes, I want it on my PC, in my system.

I only tried to put it on a stik because the instructions said to do that.

Thanks Nick

Oh & as you suggested above, I also just re-downloaded from http://releases.ubuntu.com/12.04/.

What I got there is "ubuntu-12.04.1-server-i386"; identified as a "Disc Image File" size 645 MB (676,638,720 bytes)

Remember to MD5 test the ISO you download :)

Ubuntu server has no Desktop Environment. Are sure you want Ubuntu Server ? Do as @actionparsnip suggested and Check MD5 first.

OK I went back to your message of 31 Aug, Nick.

Went back to unetbootin site.

This time instead of trying to apply unetbootin to an ubuntu iso I had already downloaded,
I clicked to just LET UNETBOOTIN DOWNLOAD the iso AND set it all up.

THEN it all WORKED. I have Ubuntu up & running.
YAY!

Thanks a million for all your help.

I have a new quesiton. Would it be OK if I e-mail you?

Thanks NikTh, that solved my question.
