Can't boot on the install CD

[pieroxy]

Hi,

I burned the install CD for Jaunty and whenever booting on the CD, I can see the menu and then select whichever options that I choose, I see the CD that starts booting (Ubuntu logo and the moving progressbar) and after a few seconds I get a BusyBox shell. Apparently it cannot mount the root fs because as soon as I leave the shell I get an error message saying that it cannot mount /newroot.

Whenever I try to mount the newroot myself in the busybox shell I get the error message "Invalid Argument"....

I also burned a SystemRescueCd (v1.2.0) and the CD reacts exactly the same. I tried to boot these CDs on three different machines just to get the same result...

Aditionnally my HDD-based install of Jaunty does the same since a couple of days, just after having installed the package fglrx for my ATI gc, I had to hard reset the machine... I checked the FS of my root partition but it is fine (ext2fs -f didn't report anything wrong)

I tried a CD with Ubuntu 8.04 and it boots perfectly fine on all three machines....


Is it something with the new kernels? Can anyone help over here?

Thanks in advance!

Old question but what speed did you burn the disks at. Did you verify the md5sums for the downloaded files and run the disk check from the CD boot menu?

I don't know how to verify the md5sum from windows (that's my second machine, still up and running...). I tried to take all the files from the CD and copy them to a folder on my HDD with success though. That said, this cannot explain my HDD failure ;-)

Verifying the CD from the CD boot screen gives me the same BusyBox ...

I will try reburning the CD tonight though. Will keep you posted.

Burn the CD at the lowest speed.

Google doing the md5sum via Windows. You ought to be able to find something out.

Try this quick link I found:
http://www.linuxquestions.org/linux/answers/LQ_ISO/Checking_the_md5sum_in_Windows

In Ubuntu terminal you would use this basic command adding the path to the iso file you are checking.

Terminal command: md5sum ubuntu.iso

Right on spot, thanks. I burned the image again with another burner and it now works like a charm. I took this opportunity to do a fresh Jaunty install, and goodbye problems with the ATI X drivers and my sound drivers.

Thanks a bunch. I'm still appalled that I thought of the content of the CD instead of the CD itself when I tried it on three computers with the same result...

Anyway, thanks a lot for the help.

Anyone knows how I can mark the thread as fixed? I used to know these things, bu I can't see the option anywhere anymore....
