k3b won't recognize new CD-R - can't burn ISO image

[tomcloyd]

I've inadvertently wiped my desktop OS and need to reload Kubuntu. I have a verified 12.04.1 ISO sitting on the hard drive of my netbook, to which is also attached a Pioneer USB optical drive. K3b loads, recognizes that there is an empty CD-R in my Pioneer drive, but when I try to burn the ISO image, the modal window for this special task insists that I need to load an "empty medium". I tried every trick I can think of, and multiple new CDRs. Nothing works. If I cannot burn this ISO I cannot reload the desktop OS, so I'm rather desperate.

The USB optical drive is essentially new, and has seen little use. It's work fine before, although I'm not sure I've ever tried this particular thing with it before. If I remove the CDR and replace it with a DVD, k3b detects this just fine. If I try to burn data files (not an ISO) to a CDR, k3b accepts the CDR just fine.

Any ideas as to how to get this working?

until this gets sorted out for real use the DVD ....it will work .

Maybe the ISO won't fit on a cdr?

[blobfish]

I wonder if you could mount the image and then burn a data cd instead of an image?

[SecretCode]

Maybe the ISO won't fit on a cdr?

I suspect this. It would in any case be useful to test burning a different iso. Perhaps a recovery disc like parted-magic, which could be useful to have around.

[tomcloyd]

OK - the problem WAS that the ISO is too large. I just burned parted-magic without any problem. Thanks for the tip. Now...why does the Kubuntu 12.04 (360) CD iso not fit on a CD? Baffling. I could burn the DVD, but that's not really what I want. Any ideas how to fix the "won't fit" problem?

[Snowhog]

Are you sure you downloaded the 12.04 iso and not the 12.10 iso? The 12.04 iso is the correct size and does fit onto a standard CD. The 12.10 iso is 'oversize' and won't. Now the 12.04.1 (daily build) is oversize as well, at 703Mb.

[benny_fletch]

I had this exact same issue with 12.04.1, it would not fit on a CD because the ISO size was 703.3MB. Thus I too had to burn it onto a DVD. Just FYI.

Oops... I now see Snowhog stated this in his post as well (sorry!). I guess I better stop speed reading.

[tomcloyd]

Well, heck. I simply don't get this. How did I make this mistake, I'm wondering. It turns out that I didn't.

At the KB download page one is faced with a "download Kubuntu" button and a section on BitTorrent download, which are what I always use.

Click the "download..." button and you get a choice between two 12.04.01 ISOs. Uh...which won't fit on a CD. Or maybe it will if you download THIS way, which takes hours, which is why I never do it. I don't know if it will fit because I'm just a dumb regular user and I don't remember this sort of minutia. I assume that the Kubuntu won't toss me a bomb. Trusting, aren't I...

But I'm a BitTorrent guy, and that's what I used before, to get an ISO that won't burn to a CD. It turns out the bittorent ISO is (as the page section that opens up when you click the "download Kubuntu" only 12.04.1. I've already gone this route and it was a deadend.

I'm smart enough to search for and find a bittorrent 12.04 version I can actually use, and I will, and that will fix my problem.

But what's with the KB website's directing people to ISOs they cannot use? (Yeah I tried burning my 703.3 MiB 12.04.1 ISO to a flash drive. It wouldn't boot. Don't have time to make sense of this. I have work to do.) This is nuts.

[Snowhog]

Go to this reply for the link to the 'correct' sized 12.04 iso images.

[GreyGeek]

Yesterday I tried to burn the 703MB Kubuntu 12.04.1 ISO and K3B failed 3 times. I thought it was a permission problem but it wasn't. An previous upgrade unchecked the "Overburning" option. I rechecked it and today I burned a 703MB oversized ISO and it burned OK in K3B. On the Advanced tab IIRC.

[tomcloyd]

OK, but...the torrent link there doesn't work (no seeders), and I cannot for the life of me find a MD5 string for the regular 386 download. You'd think it would be here, but it's not. I find this all rather surprising, probably because I've not seen this kind of chaos with these downloads until now. I AM grateful to have an ISO downloading now (non-torrent version) which just might work.

Sigh. I guess I shouldn't be surprised at this point, but...here's the full text of the page at the link I give above [http://cdimage.ubuntu.com/kubuntu/re...elease/MD5SUMS]:

What I wanted is simply not there.

Could it be because I lack the "Snowhog" addon to my OS? Wonder where I can get that (and I sure hope an ISO is not involved...)

Thanks again for your very timely and helpful responses. My download checks out and I about to burn it. If my computer doesn't self-destruct I just might be in business!

UPDATE:

That's not the page YOU were looking at. This is. Note the URl diff -

That's because that link doesn't contain the desktop i386 12.04 iso md5sum, nor the not-oversided LiveCD iso for same.
