cdrecord - iso won't boot; md5s don't match

I'm on the ropes again. I've about had it with Slack and Linux. I go through these phases where I love Linux and I freaking HATE it. I am *sick* of trying to make *peripherals* work. I do *not* want to be a Guru of All Things. I want to settle down to some nice bash and grep man pages and start scripting text manipulation tools and whatnot. I do *not* want to learn about 'pads' and 'DAO' and 'scsi-emulation' and all this... crap.

Anyway - to the issue: trying to burn a bootable .iso because I was clued in to a Slack live CD and really don't want to reboot into Windows so I can burn it. (Which works flawlessly, btw.)

I should have posted this a long time ago. Now I'm so confused I don't remember what I tried and what the errors were. Long story short, the thing doesn't boot and the md5 doesn't match. At best, there's what looks like a good file system there, but that's it. (The iso md5 and what I downloaded *do* match - just not what I burn.) At worst, it's a coaster.

A couple of the many things I've tried to read is
http://www.troubleshooters.com/linux/cdrw.htm
and
http://www.troubleshooters.com/linux/coasterless.htm
which seem to have screwed me up worse. I've also been reading every cd-related thread here at LQ that's come up for the past few *weeks*.

There's like a '-b' option on cdrecord that I missed somewhere that makes it bootable, right? I just know it's something either impossible or incredibly, mind-blowingly simple. And I was so happy when I got it to burn anything at all and play CDs and let me do so as user and so on. *sigh* - this last step is killing me.

Don't ask me 'What errors were you getting?' because the answer is extremely long. I'm posting some of them anyway. Sorry - but it can be skipped.

The last bit was mostly:
