This sounds like it is most likely to be a broken CD. This could be that the CD is scratched or warped, burnt at too high a speed for the disk or drive, or even burnt from a broken ISO download.

There are some other possibilities; you might try looking at the menu that appears just before Ubuntu loads for options like "safe graphics mode" which fixes some problems. But loading initramfs is one of the first things that happens, and it only uses the CD and memory, so it's more likely to be the CD disk itself. At a stretch, it might also be the drive or even your RAM; have you used the drive recently?

You might try looking at http://www.ubuntu.com/GetUbuntu/download for other ways of getting a working boot CD. Also try booting the CD on other machines if you can (you don't have to install it) to check the disk.

Hope that helps,

Thanks Robert

I have got ubuntu loaded from the other drive but now it fails to boot
as it still tries to boot from the cd and i get initramfs again..Auto supergrub does not fix the
problem and just hangs.I think it is something to do with having 3 hard drives and one of them has 2 partitions.I think it is confusing grub
somehow.
It all worked fine before I added the 3rd drive.

Thanks again

Dave

Did you alter the order of your hard drives? If Ubuntu was on the second drive, that drive may now be the third one. I don't thinkg that should happen though considering that Ubuntu uses UIIDs as partition identifiers. I am thinking that your hard drives are connected to more than one controller, is that right? Debian based distros tend to get confused under those circumstances. There is a workaround but it involves some editing of your fstab and grub. Or, if possible, you can connect all your hard drives to a single connector.

If the third drive resulted in a hang on boot, it may be a power supply issue. Just unplug the power from that drive and try again, then plug it in and try again ...

Third hard drive

I use sata drives c,d:and the last one fitted is e thats in windows
but ubuntu grub sees drive e as the first drive.

I will try again unplugging the last drive as suggested.

Thanks for the help

Just unplugging the drive is not going to be very helpful if you intend to plug it in again. See my previous post. If Ubuntu sees a different driver order, it would perform what I expected: either you need to go into BIOS and reorder your drives (how windows sees drives is irrelevant if you boot it from GRUB) or you need to make sure that "E" is connected to the same connector as the other two.

Now Installed

I basically had 4 drives.1 drive with 2 partitions and 2 other hard drives.I merged the partition on the drive with two partitions and unplugged the 3rd drive leaving only 2 drives.The installation went
flawlessly.I have now reconnected the 3rd drive and all is ok.
I only assume grub gets confused with all the drives.

Thanks for all the help and ideas.
