This Ubuntu help wiki page says that, in order to add Ubuntu on an existing Windows system, I must burn Ubuntu on a CD first. But CDs are becoming less common these days, so I wonder if there is a way to install Ubuntu without burning it on a CD (or a DVD, or a USB stick) - just download the ISO to my Windows machine and then somehow install it as dual boot.

In the past I have tried to use Wubi for that purpose, but this was not stable, and got stuck too many times. So now I want to create a dual-boot system.

To install Ubuntu without a CD or DVD or USB, you need to install Ubuntu as WUBI first, then migrate it to a hard drive partition using 'migrate-wubi'. This will work like a normal installation and won't be slow like WUBI. How to do this is written on this page

If you don't want to use a CD you can check how to boot from a flash drive here. Just follow the instructions, then plug in your usb stick, reboot and set the boot sequence to your USB port in the BIOS menu. The rest is really straightforward.

  • I think I tried this in the past but it formatted my USB stick... Is there a way to install from USB without wiping its contents? – Erel Segal-Halevi Mar 10 '14 at 13:42
  • It's not possible. – Avinash Raj Mar 10 '14 at 13:43

    I don't think so. But if the problem is to erase the content of your flash drive, you can simply make a backup of your data on your windows partition, then format the stick to make it ubuntu-bootable, install your dual boot, and finally restore your usb stick from the backup you made on windows. – Buddyshot Mar 10 '14 at 13:44
  • You can use Lili for windows if you dont want to format your flash drive. It has an option to do it without formatting – Stormvirux Mar 10 '14 at 14:13

Using a USB stick works Great! use LILI or Universal USB Installer. Both methods are very fast.
