Bug Description

Fresh install of Ubuntu Desktop 10.10, performing all online updates - reboot works fine. Then install mdadm the system does not boot any more:

mount: mounting /dev/disk/by-uuid/.... on /root
failed: Device or resource busy
...
...
No init found. Try passing init=bootarg.

That was it - havn't been able to recover the system any more.
thx for support

I think you should report this against mdadm instead ( https://bugs.launchpad.net/ubuntu/+source/mdadm/ ) since if you've made a standard hard disk install of Ubuntu then UNetbootin doesn't have anything to do with your issue.

Changed in unetbootin:
status: New → Invalid

Here some notes how to rescue the system:

Boot with the live CD.

Mount the hard-disc:
mount /dev/sda1 /mnt

Mount system folders into sda1:
mount –t proc none /mnt/proc
mount –o bind /dev /mnt/dev
mount –o bind /sys /mnt/sys

Change the apparent disk root directory:
chroot /mnt

Now delete all occurences of mdadm:
find / -name mdadm | xargs rm -r

Now call:
update-initramfs -u

With this a new ramfs is created without mdadm - the system boots again.
