OS will no longer boot OR from CD!

[Ulrich]

I am using an alternate computer to try and solve this problem. Recently I switched out a DVD-RW for a new one, a dual layer burner, and now have problems getting Ubuntu to load. I also recently moved and am hoping I did not simply jar something loose. Also, I wonder if I may not have the settings re: master and slave set up properly or if this error has to do with my drives at all.

It goes fine and through the loading bar as if it is going to boot, takes an extraordinary amount of time to do so, then doesn't and reads, among other things:

"missing modules 1s/ dev"

I know this is not a lot to go on but I have precious little to offer. Is there something to look for regarding the drives?

I do believe everything is plugged in tightly.

Help! I can't use my computer at all and have been without for two weeks now! In fact, I get the same error attempting to reinstall Ubuntu from the CD I used originally.

Also, before these problems occured, I attempted to upgrade to Ubuntu Studio (not the new version) and did not have an internet connection when I did so so I did not get to download certain files it wanted to but it just seems odd that booting from CD and re-installing won't even help.

1st of all be sure that all devices are recognized correctly at the POST screen, if to an the ubuntu install prompt apears, try to use some special options like eg.
noirqpoll or noapic, I think you can get those options show using F6

The first screen goes by way to fast for me to check anything at all. My monitor is not showing anything clearly before that screen is gone but in addition, it is going by much faster than it used to.

I did just notice something else though. It seems that the "missing modules" error is merely what is shown as a list of possibilities as to what might be wrong. First, there is an error trying to read it at the normal screen resolution, then another error shows as it tries a lower resolution, then the overall failure. Then is a list of things like "did it wait long enough" and so on...

This motherboard has way above average built in graphics. Everything seemed fine until I tried to install Ubuntu Studio AND the move to my new home. I hope something did not jar loose.

I wonder if there is some problem now with the monitor. Could that feed back into the boot as an error?

Also shows this:

"Gave up waiting for root device"

then the list of suggestions

This also turns up:

alert /dev/disk/by-uuid/bf642119e-7486-a7ce-4b21b65c7bea does not exist

dropping to a shell

[odcheck]

Ok so as it tells, alert /dev/disk/by-uuid/bf642119e-7486-a7ce-4b21b65c7bea does not exist

It seems that the uid of your root partition / hdd has changed sinced you've swapped the dvd drive.
So you could repair you're installation using a rescue cd (just boot the ubuntu in live mode) and within the /boot/grub/menu.lst there's something like

kernel          /boot/vmlinuz-2.6.18-6-686 root=/dev/sda1 ro
initrd          /boot/initrd.img-2.6.18-6-686

but in you're case instead of root=/dev.... there is a uid given. So you'll need to figure out what's your root partition and just change the line.

I don't think that your monitor is defect. If you're able to Enter the BIOS Setup (del, or F2 something like that) there must be a option called e.g. quickboot enabled or similar. If you turn this to disabled. I promise that you will see something from the post.

On hitting F4 for modes I get the following:

normal
safe graphics mode
use driver update cd
OEM install (for manufacturers)

Is one of these "live mode" as you call it?

I am quite a noob. I have tried to take care of this problem at other forums without any answer from anyone so your help is more than appreciated!

[Ulrich]

I tried using Ubuntu booting from CD as a trial without installing and didn't get the usual error messages but got this instead:

BusyBox v.1.10.2 (Ubuntu 1:1.10.2-1ubuntu6) built-in shell ash

Enter 'help' for a list of built in commands:

(Initramfs)

It appears to be awaiting commands at this point.

I am using Intrepid Ibex because the update to 9.04 would not boot. As well, I just entered the advanced bios features and get the following menu (lookin for "quick boot"):

-cup feature
-shadow setup
-cache setup
-boot seq and floppy setup
virus warning enabled
quick power on self test enabled
boot up numlock status off
typematic rate setting disabled
-typematic rate (chars/sec) 6
-typematic delay(msec) 250
security option set up
mps version control for OS[1.4]
os select for dram > 64 MB [os2]
delay for hdd (secs) [0]
small log(epa) show enabled
summary screen show enabled

I know there is a chance that this is all useless but I am doing everything I can to help you to help me!

...and thank you!!!

Something is wrong with Ubuntu CD only. Have your verified MD5SUM of downloaded .iso image? Burn .iso image again at lowest possible speed supported by your CD/DVD Burner.

So what he says could be possible as well, but what I mean is that you should try to boot with the 9.04 i386 version, and after you've choosen you're language.
Press F6 and some special boot options will occure. There you should try them step by step. Cause I guess that Ubuntu has quite a little problem to boot your detected hw-setup correctly. I didn't mean press F4 this is not goaly
