what are bootcodes and when or where do I enter them?
waitusb=5 is one.
tce=UUID=6C98-30DD is another. did you get that uuid yourself or is it someone else's? if it's not yours it shouldn't be very useful, it's for identifying a specific device, like a specific usb key. see the faq from the main website for how to find yours.
i think those bootcodes are in the right place.
without the right uuid (or, you can just use the /mnt/location if you know which /mnt your storage is...) it's not surprising that it's not putting tce's there. but i don't know why they're going to /home/tc of all places.
