I found an article from 2007 on how to install Linux without using a USB stick or a CD at I was wondering if anyone could tell me whether this still works, given it's five years old. For starters I found that the initrd.gz file doesn't seem to exist but a initrd.lz file does.

Edit: And when I do try it, I get an "Error 21: Linux kernal must be loaded before initrd".

It might be better to ask how to do what that howto says here so we have something up to date. – Jorge Castro Jan 25 '12 at 23:47

My guess would be that it will not work. That tutorial is for Windows and if you are running windows you are going to have better luck with wubi.

You download the wubi.exe from here:

You run the wubi.exe like any other application and the installer will download the iso and install Ubuntu.

For additional information on wubi see

I would love to use Wubi, but… explains why I'm not using Wubi given no one appears to know a workaround. – dlanod Jan 25 '12 at 23:57
Nasty bug. You are going to run into that bug no matter how you boot the iso. Can you boot the laptop from a usb or cd ? – bodhi.zazen Jan 26 '12 at 0:04
It doesn't support booting from USB (too old) and the CD drive is defunct (too old). – dlanod Jan 26 '12 at 0:32
You should start a question with a better description of your problem and the specifics of your hardware. How much RAM ? Your best bet may be to use grub2 to directly boot the desktop.iso. You can then partition the hard drive manually and install using chroot. The details would be moderately technical. See:… and . You perform a minimal install with debootstrap, then chroot and install ubuntu-desktop and a kernel, then re-configure grub to boot the debootstrap. – bodhi.zazen Jan 26 '12 at 1:16
