I am a complete Linux Newb altogether and I had this ramdisk error coming up with my 1st try at installing Mandrake 10.1. I finally found out what was causing it.

My CDROM drive!!! I have never had any problems with it on windows apart from it being rather slow. Its seek times etc are quite poor and the time that the install allowed wasn't long enough for my CD drive.

I changed it to another I had and it worked 1st time.

Try IT!
