Was it sampled from a song? Was it created as original content for the operating system?
I am running a laptop with Windows 7 and Ubuntu 12.04. I had grub issues following a partition resize which were eventually found to be problems due to missing kernel files. (These problems did not begin until a week after the resize, during which the computer continued to work perfectly).
By chrooting into my hard drive install from a 12.04 LTS LiveCD I was eventually able to restore /boot/initrd-3.2.0.24-generic.img. By copying vmlinuz from the LiveCD's /casper/ folder to /boot/vmlinuz-3.2.0.24-generic I found that update-grub would finally recognize and add my Ubuntu install to the grub menu, which was my initial problem.
However, my new problem is that when booting into this install I am met with all kinds of failed modules and error messages, often far too fast for me to even read or remember; finally I am given the option of starting Ubuntu in Low Graphics Mode, Troubleshooting, Command Prompt, Networking etc... Selecting Low Graphics Mode just dumps me out at the terminal prompting me to login, but my user name and password do not work.
Perhaps simply copying the vmlinuz from LiveCD has caused these errors? My problem is that an appropriate vmlinuz was not installed by the same kernel install process that restored my 'initrd-....'.img
I would really prefer not to have to reinstall the entire Ubuntu partition again as I had a lot of customized settings for various programming environments I use for my research work and I am currently abroad, limiting my bandwidth which is quite necessary to restore much of this software.
I do however have a complete image and a complete clone of the non-booting partition (both via CloneZilla); I just don't know if these actually acquired my private 'Home' folder, which claims to be unreadable when I mount the clone.
I am dual-booting Windows 7 and Ubuntu 12.04. I reduced my Windows 7 partition and increased my Ubuntu partition using gparted from a 12.04 live CD. Everything was fine for about a week. Then the other day I booted and was met with "grub rescue." I purged and re-installed both grub and then grub2 as per the many tutorials on line, but all efforts have met with the same results: It seems that os-prober sees my 2 Windows 7 (actual and restore) partitions, as well as the Ubuntu 12.04 LTS partition; but when I run any variant of update-grub or update-grub2, it only detects the 2 Windows 7 partitions. As a result I cannot boot into Ubuntu (which is where 99% of my work is). Here is the output of bootinfoscript:

And of sudo os-prober from 12.04 LiveCD:

/dev/sda5:Ubuntu 12.04 LTS (12.04):Ubuntu:linux
I have read pretty much every guide, tutorial and question that exists out there for updating any version of grub, but nothing has worked. But what is most confusing is that os-prober sees the installation; I would very much appreciate any assistance in this matter.
