I was asking because I had received a laptop a while back where I had
the problem of a broken Optical drive. I couldn't install a fresh
operating system without first using an optical drive, as the BIOS
didn't support USB booting. I did end up taking apart the laptop and
using a different laptop's optical drive to boot and install Lubuntu. I
was wondering if this provided some awesome (and seemingly impossible)
solution to something I had encountered that I couldn't find a
workaround for. I suppose this is something that would be hard to do,
unless you had 1 specific BIOS you were targeting and knew the internals
well enough to hack around and get a hack to boot from a USB.... :(
Though I am sure this will be a handy tool to have. It seems like there
are quite a number of us here that get old 'broken' WinXP computers and
have to do some clever things to get them to boot, and function (reminds
me of Ali's current battle with his Laptop).
Fortunately hardware vendors are beginning to work to make things easier
for us now, rather than difficult (except the silly M$ UEFI debacle...
though EFI to boot straight into Lubuntu would make boot times
phenomenal rather than using GRUB... like a Mac does with its EFI)

Hi again,
Or do you mean the general question, how to install without CD/DVD/USB?
Yes I can. I would take advantage of the portability of the Ubuntu
family systems, connect the internal drive to another computer and
install the operating system. It will work after you reconnect the
internal drive into it's original computer except when UEFI causes problems.

Hi Israel,
The USB bootloader is meant to work like your second alternative, to
help booting from a USB device, that will not boot from the computer's
own boot menu.
But of course, if it is installed into an internal or eSATA drive, it
will help booting, but that is better catered for with the '40_custom'
method described in the following link
https://help.ubuntu.com/community/Installation/FromUSBStick#Chainloading
The USB chainloader will not do the same thing as Plop, so it will be a
complement, not a replacement.

Can you boot computers that have no capability to boot from usb, and
have a broken optical drive?
Or is this mainly just to boot a USB stick that is not supported by the
computer to boot from?

Good question Jörn,
The USB chainloader works from USB.
I know Plop and have used it to boot USB via CD in old computers. I
tried to use Plop from USB. I could make it boot and run its menu, but I
was not able to boot another USB device from it, at least not with the
fairly modern hardware that I tested (for example professional class HP
laptops, the newest one with Intel i5).
Under the hood the USB chainloader is a stripped system based on Ubuntu
13.04. The grub bootloader and the boot directory is what is kept, and
the file grub.cfg is modified.
So I would say that the USB chainloader is a complement to Plop. I'd be
happy if you can help me boot from USB with Plop and chainload into
other USB devices, because it would make it easier to have only one tool
for these similar purposes.

What is the difference to Plop boot loader?

Hi,
I just finished a little tool that helps boot some computers from
[other] USB boot drives - the Chainloader
The chainloader is useful for middle-aged computers, for example
computers without a CD/DVD drive, where it can be hard to boot from a
USB drive, or when you want to run from a fast USB 3 drive that is
unwilling to boot.

What is new, why a new tool? Isn't it enough to be able to use mkusb or
the other tools?
The answer is in this tutorial 'Howto help USB boot drives'
http://ubuntuforums.org/showthread.php?t=2196858

Phill, can the compressed image file be uploaded to your server? Maybe
it is too small to have an own link or page. Maybe it can share a page
with mkusb. What do you think?
Best regards
