Can't burn Utopia Bootdisk!! (long long sentense)

[Kei]

Hi I'm Newbie!!
Well, First I want to introduce myself
My name is Hiraku, I'm 19 years old.
I'm Japanese,but live in Australia (Brisbane).
So, Sorry about my crappy English.

Well, I have trouble with burning Boot disk(not game, maybe I will ask how to burn game, ahahaha)
When I use Disc Juggler to burn Boot disk.

~~~~~~~~~~~~~~~~~~~~~~~~~~
277 Testing Session 1 of 3....
278 Testing track 1 of 2......
17778 No seek complete (error)
277 Testing session 2 of 3....
278 Testing track 2 of 2....
276 Task completed in 00h:00m:16s
~~~~~~~~~~~~~~~~~~~~~~~~~~
then freeze CD-RW(I use "Diamond 32*12*8)
I didn't change "Advanced setting"
I uninstall and install again, then tried, but same result.
My Nero version is 300.800(trial version)

So, I used Nero's boot disk.
I could burn boot disk, but didn't work.
When I burn boot disk, Nero asked me
"Do you want to use "track at once"?"
When I say yes, Dreamcast read with some strenge noise, then
go to CD PLAYER.
When I say no, Dreamcast can't read (like CD is not in).
Nero version is 5.

So, what can I do?
Is my setting wrong? if it is, plz tell me all detail setting
or better to make self-boot games?

P.S I bought Dreamcast in Japan at when it is come, So
I don't think my Dreamcast is new version.
