How to Install Ubuntu without USB or a disc

I believe there is a network installation available for Ubuntu, not 100% sure about LUbuntu.

If you are using Windows on the laptop right now, you could use WUBI to install Ubuntu, then open a terminal or go to a TTY and enter,

This long command will remove Ubuntu and install LXDE. For other distros see this page.

Hope it helps!

I found several options for this scenario here: https://help.ubuntu.com/community/Installation#Server and network installations

If you have an extra partition, you could "burn" the installer to that partition and set it as the active partition. Then reboot and boot from it. You may also have to resort to a bit of trickery if you need to create a separate partition: resize the filesystem and its containing partition. I've had some various scenarios myself where I had neither USB boot, nor a disc drive.

You could move the hard drive to another laptop or computer to install then put the hard drive back into the original laptop. Admittedly a less than perfect option but it will work. I keep a couple of old hard drives with Lubuntu on them for testing any computers I pick up and because of the way Linux/Unix loads drivers, they usually boot without problem on all sorts of hardware.
