How to install CentOS 6 from a USB drive with UNetbootin

I believe I'm one of the poor souls who tried to install CentOS 6 64-bit on a laptop with no DVD drive with UNetbootin. I need a full Linux test environment as I'm testing the directory server and a few control panel software and its integration with my Baby Gekko CMS. I tried putting the 4Gb ISO onto a flash drive along with the 4GB image that was created. Then as I was going to mount it, I couldn't go to tty2 since Anaconda installer hasn't given me a prompt yet. I got this error:
The installer has tried to mount image #1, but cannot find it on the hard drive. Please copy this image to the drive and click Retry. Click Exit to abort the installation.
So I finally used the CentOS-6.0-x86_64-netinstall.iso with UNetbootin, then extracted the 4GB ISO disc 1 and 2 into a newly created directory in my local EasyPHP development server. I tried again and things are finally looking good, I finally got the graphical installer to show up. It was saying

Then I got this cripting error
Unable to read package metadata. This may be due to a missing repodata directory ... and there was this file ffb0e227e2cdd8a2b3609b65d7f38f6c1e756b437405b2918d6d36ebe59a0cb4 that was in the repodata dirtectory that couldn't be read or something like that.
I was in disbelief, so I tried going to the FTP site and looked up went to /pub/centos/6.0/os/x86_64/repodata and apparently the files were different than the one in the ISO. Then I deleted all of those from the repodata directory and replaced it with this one. Voila - my CentOS 6 is finally installed on my Dell Vostro V131!
