I want to install knoppix dvd and I can't do it. I installed one time succesfully though.
However I can install knoppix cd, and begins installing with 1%, while with dvd it begins with 80% and it stucks there. The percentage don't move anymore. These are the partitions I have:

01 sda-1 free hidden 7.81 mb
02 sda1 extended 56 gb
03 sda5 reiserfs activa 56 gb
04 sda3 linuxswap 3 gb
05 sda2 fat32 15.42

so it always ask me to install in sda5, it doesn't give me other option.
I also don't know what is the sda-1 partition, with hidden state, is it usual to have this in the hard drive?

Thanks and regards
