Reboot message on boot

[Macboe]

I just installed 10.4.8 JaS for maybe the 4th time, and every time the installation goes fine, but when it restarts a message comes up over the apple with the white background and tells me to restart. I booted into verbose mode and the only error I noticed was something with NVDA10. Then it says the Login window app is started and that's it.

 

The first time I installed I had every option checked except AMD. This past time I only checked Intel. Here are my specs:

HP864n Desktop

1 GB Ram

150GB hard drive

Intel Pentium 4 (I think it is SSE3, but it's not like there's a choice anywhere)

Graphics card came with computer built-in, I think Nvidia TNT RIVA or something

 

I would ideally like a dual boot with XP (I also have the XP CD so I can install it after or before if need be) but first I would like to make sure OS X will work on it. Installing osx86 took much less than an hour, so if I need to reinstall it again that wouldn't be too much trouble, although it seems that I have to delete the installed Mac stuff before it boots onto the install DVD. I also have an ubuntu live cd if that helps.

 

I searched and some other people have had this problem. I followed one guide that had me boot into single user and delete some files, but it didn't work.

 

If anyone can help me just get this restart message away and osx to boot, I will be very grateful.
