Ubuntu – Is it possible to install Ubuntu without a CD or USB drive?


So basically as it stands I have a laptop which has no cd/dvd drive, and I don't have a usb drive.

The laptop has windows 7 installed with ubuntu 11.04 installed through wubi.

What I want to do is remove windows completely, and make ubuntu the only OS installed on the system.

Is there a way to do this without re-installing ubuntu? (i.e. can I take my wubi install away from windows?)

or is there a way to from inside ubuntu have it run the ubuntu iso somehow so I can just wipe the system and install it fresh? (even if it means I need to have an e.g. 2gb partition just for the image to reside in).

  1. Use Windows 7 to shrink one of your partitions (you can shrink a mounted partition while running Windows). If you already have 4 primary partitions you'll need to remove one of them first.
  2. Boot wubi and install GParted and create an extended partition in the free space you created, and then 2 logical partitions, one an ext4 partition large enough to contain your Wubi install, and optionally 1 swap partition (> size of RAM).
  3. Migrate wubi to the partition, installing the grub bootloader at the same time
  4. Boot the migrated Ubuntu and format the Windows partition, which you can then reuse as a separate /home or you can use the same migration script to move the migrated Ubuntu to it.

This solution doesn't require a live CD/USB (although it's always a good idea to have one.
