Don't have the administrative password for XP Pro

::I am in the XP recovery console and I am stuck from going further
because I do not have the password. I can't get into my drive to change
it because it will not boot. I am somewhat painted into a corner. I
thought there was a work-a-round process to either get a password or
circumvent it all together. I am having an issue with a \"Boot Manager
is Compressed\" error so it won't let me access my main drive. ::::

::I really created a mess here and I hope someone can help me sort
through it. I got vista ultimate and I wanted to set it up on my
computer along with XP Pro. The Os's would be on separate hard drives.
::::What I did was clear out an existing hard drive and cleared out the
partition so it was an unpartitioned space. I shut down the computer
with the boot disc in it, restarted and it seemed to install fine. I
selected the unpartitioned space the installations went through all the
motions and what seemed like its last reboot it starts to install all
over again. That's when I get errors like \\"boot manager is compressed.
I disabled the drive that vista was installed on so I can get back into
my XP program and I get the \\"boot manager is compressed\\" message
also. I have a hyperthreading 3.4 ghz processer 3 gig of ram. I had
heard that anything more than 2 gig screws up the Vista install, however
this one seemed like it went all the way through untill it started
reinstalling of course. I tried using the Vista disc to repair the boot
problem but it never gives me the opprotunity because it goes straight
to the installation mode. Any suggestions?::::
