everytime I try to boot the usb I get an error in regards with Syslinux and COM32
The Syslinux version installed and the COM32 (R) files (and all other Syslinux files like for example memdisk) need to be of the same exact version.
Download the latest Syslinux, expand it, and replace every Syslinux file that currently resides in your UFD with the latest version you downloaded.
The only "problem" is that Syslinux has all the final binaries distributed in several different folders/directories of the zip package, so you need to do this manually.
After copying (replacing) the relevant Syslinux files, run Syslinux.exe from the UFD. Then you can reboot your netbook with the UFD.
1_ Backup any files from UFD that you want to save.
2_ Format your UFD (with RMPrepUSB if it worked for you). This shouldn't be a necessary step, but who knows.
3_ Expand your (customized) UBCD ISO image, if you haven't done it yet.
4_ Go to ubcd\tools\win32 (or ubcd/tools/linux if corresponds) in the UBCD expanded tree.
5_ Open a command prompt there.
6_ From the command prompt, run the ubcd2usb script.
Let us know if anything of this works correctly.
