Karmic Alpha 6 will not boot from Live CD

[Graham Lavender]

I created a Live CD of Karmic Alpha 6 (desktop 64-bit), but it will not boot. After I select "Run from CD without making any changes to my computer," it brings up a number of text messages and then goes to the screen with the Ubuntu logo, the horizontal lines that move down the screen, and the spinning pointer. Then the screen goes blank for 5-10 seconds, then the same screen with the moving lines, then blank, then moving lines, and this continues indefinitely until finally I have to shut down the computer.

I was able to run Alpha 4 from a Live CD, and I was able to install it, but after updating it and then restarting my computer, I had the same problem described above. Neither Alpha 5 nor Alpha 6 would boot from the Live CD at all.

I have no problem running Jaunty on my computer. It is a brand new machine I assembled myself, though I don't know much about computers. It has an AMD Phenom II X3 processor and Radeon 3300 integrated video.

This bug also effects me.

What messages I could catch:

init: line 1 Can't open medium /dev/sr0: no medium found

[QIII (qiii)]

Confirm SYMLINK message, both on attempt to run LiveCD and attempting to install both 32 bit and 64 bit versions.

Also encountered this error attempting to reboot after using apt-get upgrade prior to attempting to use new ISO image.

Same problem on a Toshiba Satellite A300 laptop.

[Stéphane Maniaci (stephh)]

Same problem here, trying to boot the lastest LiveCD. ATI Radeon HD 3870 & AMD Athlon 5000+.

[Chris (cdekker)]

Same problem here. My motherboard is a ASRock AOD790GX with HD3300 IGP. This problem didn't exist for me in Karmic alpha 4 but appeared in alpha 5 and hasn't changed in the alpha 6 release. In alpha 4 the splash screen is incomplete in that it only shows the background and not the Ubuntu logo and the white bars but at least it starts the Gnome login manager so I can use the system. Alpha 5 and 6 seem to be stuck in a loop (re-initializing X-server or hardware over and over???) before they even show the sign-on screen.

[Chris (cdekker)]

I should have added to my previous post that I booted from a USB stick using an image from the Ubuntu 'USB Startup Disk Creator' application.
Not sure whether this is related or if it is a different issue but when I tell GRUB to boot directly from the downloaded ISO image, I do get to a desktop without signing on; however my (wireless USB) keyboard and mouse are locked out and I need to hit the reset button on the console to regain control of the computer.

same problem here on thinkpad T61 ..

[Chocwise (chocwise)]

Same Problem with the Toshiba Satellite P200 1FT of my dad and Alpha 6 Live USB.
It kept crashing while showing the loading screen as described by Graham. And when I tried to jump into the console with Ctrl+Alt+F1 there were glitches and no console.

[Shaun Crampton (fasaxc)]

Affects me too, with Radeon HD 3300. When I try to VT-switch to the console a strip of coloured pixels appears across the top of the screen then changes as I type (as if the characters are being written into the video memory?)

[Robbie Williamson (robbiew)]

Can I ask what happens if you try booting from the latest Daily Image?:
 http://cdimage.ubuntu.com/daily-live/current/

[nospoon (ben-james-jones)]

I used today's image and it hanges on a screen with a blinking '_' after doing install or try ubuntu boot options.

[Robbie Williamson (robbiew)]

Scott,

Can you take a look at this one? Are the daily live CDs missing your recent fixes, perhaps?

[Scott James Remnant (Canonical) (canonical-scott)]

The original reporter says that Alpha 5 fails to boot for them as well, so it has to be unrelated to any boot migration changes.

Also reading the description, the reporter describes seeing the Ubuntu Logo with moving lines, ie. the xsplash screen as it existed in Alpha 6. He also confirms seeing a spinning pointer. You would only see a mouse pointer if X was running.

The screen goes black, and then the logo sequence starts again.

This description is consistent with a crashing X server.

[Scott James Remnant (Canonical) (canonical-scott)]

Reading the further comments, this appears to be describing a regression with support for ATI graphics hardware from Alpha 5 onwards

[nospoon (ben-james-jones)]

I had this problem with an nVidia card, so I don't think its related to ATI hardware.

[Chris (cdekker)]

I have tried the September 24 snapshot per Robbie Williamson's request. It does make a difference but not in the way I would like to see. The splash screen is now black with the Ubuntu logo (circle only) showing in white in the centre of the screen. After about 15 seconds the screen changes to just a binking underscore on a black background. If I hit the enter key at that point I get a console with 'Ubuntu login:' as prompt.

Can you let me know the number of the original bug report if you want to continue to receive comments there?

[Graham Lavender (glavender)]

I tried the Sept 25 daily image and had the same experience as Chris - plain white Ubuntu logo, then text prompt, and after hitting enter:

Ubuntu karmic (development branch) ubuntu tty1

ubuntu login:

[bernhard (bernhardredl)]

i tried the beta desktop live iso (amd64)

but i also can't boot (Nvidia GT250 card). After 2 secs there is lust a black screen an a cursor is blinking (nothing is happending)

this live cd worked fine on my notebook (intel graphicscard)

(i'm not sure if this is realy a duplicate of the mentioned bug, because at my screen there are not error messages displayed ( i displayed the quit option to make sure)

[Graham Lavender (glavender)]

I'm pleased to report that this bug no longer affects me with the Beta release of Karmic. Karmic Beta runs from the Live CD and I have also installed it successfully. Unfortunately, the update manager and software center both consistently fail, so I have filed bug reports about them.

[Chris (cdekker)]

My system is also starting up just fine using the AMD64 beta release. All the issues I had with the alpha 6 release seem to have been resolved.

Downloaded Kubuntu 9.10-beta (32 bit) on 8th Oct. Used 'Create USB Start-up Disk' from my system (Ubuntu 8.10) to create an image on an 8GB USB disk. Tried on 2-3 computers, same error: /init.... /dev/sr0: No Medium Found

Got this when pressed ctrl alt F1, otherwise just hung up on the kubuntu logo screen.

[dirk (dirk-kuijsten)]

Same on my old laptop and under virtualbox: ubuntu 9.10 on usb cannot find a medium. But this isn't a duplicate of #419126

[dirk (dirk-kuijsten)]

found my problem, which was not related to this bug: my usb disk did not contain the hidden directory ".disk", which is used to check the disks contents.

[Fernando J. Cordeiro (perfectron)]

I have exactly the same problem with Ubuntu 11.04.
However, my notebook do not uses a ATI Graphics Card, so I think that it is not a duplicated bug.
