After having enough of Windows' instability, I have decided to migrate to Ubuntu permanently. I have Ubuntu installed through Wubi and I am wondering if there is a painless way to delete windows files. Thank you.

You are using Wubi. The Wubi Ubuntu system is stored on the Windows partition. You are going to have to migrate your settings to a full Ubuntu installation one way or another. – iglvzx Mar 5 '12 at 22:00
@iglvzx Does the bootloader require windows? – Nyx Mar 5 '12 at 22:02
Do you need to keep any configurations you've already made on your Wubi Ubuntu system? If not, then you can simply burn the Ubuntu ISO, insert the CD, turn off your computer, turn it back on, boot from the CD, and then install Ubuntu. – iglvzx Mar 5 '12 at 22:08
Would an admin please move this to AskUbuntu? – Nyx Mar 5 '12 at 23:34

I typically have folks run a Wubi install for a week or so before migrating to be sure. From where you are I would suggest the following route to a dual boot system.

Remove the Wubi install using normal Windows remove software procedures.

Remove large un needed files from your windows system.

Use a good defragger to consolidate the files on the windows install.

Use a live boot Ubuntu USB and GParted to shrink the windows install partition to a reasonable minimum, I say this because it is already installed and you never know when having a windows system available to test something or whatever will come in handy.

Install Ubuntu in the un-used physical disk space. Ubuntu will become the default boot and will be the fully functioning primary system with no restrictions. You may be like me and never boot Windows again, or you might find a reason to use it for something on rare occasions, whatever the reason, it only costs a few Gb.

With regard to the boot loader question. If you install Windows first and then let Ubuntu take care of the dual boot afterward during it's own install, or if you just completely delete windows by way of the Ubuntu installer (It will give you the "use entire disk" option), Ubuntu will install it's own boot loader and if it is a dual boot system manage handing a Windows boot over when it starts up.

I have successfully created a live boot Ubuntu USB before, but for some reason, if i try now, my machine refuses to go past the startup BIOS screen when i plugin in my USB. – Nyx Mar 5 '12 at 22:39
UBUNTU IS AWESOME!! Every live USB creator failed to work with my USB and BIOS, that is, except for the default tool on Ubuntu. I am installing a fresh version of ubuntu as i speak. Thanks for the idea. – Nyx Mar 5 '12 at 23:31
