reboot with wifislax-3.1.iso >> LIVE CD <<. login, start kde
now plugin flash drive, you will be asked about the new device, select do nothing
start qtparted, make sure you select your flash drive and resize to at leat 1gb. commit changes.
in the new free space create and new primary partition type ext2, commit changes take note of the partitions name, in my case I have /dev/sdb2 (fat32) and /dev/sdb2 (ext2).
reboot into windows and navigate to flashdrive \boot\syslinux open syslinux.cfg in wordpad and add this to the append line changes=/dev/sdb2 <-- my ext2 partition, yours maybe different
so look like this
