Just a thought - have you done an md5sum check and/or a media check on your ISO and CD?
How do you run the md5sum on an entire CD? It seems like it is only gives check sums of individual files.
In Linux, the command would be md5sum /dev/cdrom or md5sum /dev/dvd depending on how the links on your system are set. Haven't run Windows for years, but would assume something like md5sum D:\.
I tried md5sum D:\ on XP but it just gave me checksums of the individual files.
In any event, I downloaded the .ISO again and verified it's checksum with md5sum. Then I expanded that ISO to a directory on my disk (with AnyToISO) and diffed that directory against my CD while the CD was mounted in the target machine. This also showed no problems. So I am confident that my PCLinuxOS live CD is good on the machine where I am trying to do the install.
Now that I know my live CD is good, does anyone know why my screen goes black during normal boot?
Also, if I boot under "Safe boot" then install Linux to the HDD, will I be missing anything that I would have had if I had booted normally?
