gamefreak, E-machines are pretty proprietary to their windows OS, have your tried flashing the BIOS and updating bios to latest version then putting in the xubuntu??
another idea, (edited in after initially sending this post to wrongplanet server) have you reformatted the hard drive, are you trying to do a dual boot?? try on a new (unformatted) drive?? some things work better after installing new drive (less errors) about the errors, what specific errors are you running into??
hope this helps,
keep in touch man, miss you!
