i'm on ubuntustudio and i want to format my hd and try kubuntu (install in my acer notebook, no partion, no double operating system problem, only istall it) i've downloaded iso file ( kubuntu-10.10-desktop-i386.iso ), insert usb pen drive, then: system > administration > startup disk creator erased usb pen content, and "make startup disk" finally, reboot computer with pen inside usb port

normal boot didn't start (as expected) but only black screen with this signal:

SYSLINUX 4.03 2010-10-22 EDD Copyright (c) 1994-2010, H. Peter Anvin et al
unknown keyword in configuration file
boot:

i've tried different usb pen stick and different iso files (ubuntu, kubuntu, netbook edition).. always same problem (sometimes only the first line without "unknow keyword in conf file" error)

some advice?? sorry for my bad english
