If I boot 8.0, I lose the disc again. This is probably a dangerous dedicated disk made on 7.x I had this issue also and some member of the list gave me this hint: !!!!!!!!!!!!!!DO MAKE A BACKUP OF YOUR DATA BEFORE DOING THIS FROM YOUR 7.2 INSTALL !!!!!!!!!!!!!!!!!!! Is your disk in "dangerously dedicated" mode? If yes, this is what I did (advised by marcel@) dd if=3D/dev/zero of=3D/dev/ad1 oseek=3D1 bs=3D512 count=3D1 where /dev/ad1 is my device. You should see some messages from GEOM_LABEL removing and assigning new labels. This worked for me, i do not know if it will work for you. Regards, Johan Hendriks
