I would try to emerge grub, install and all that again to make sure everything is stable. Also, when you are booted into Gentoo, not the CD, type in the mount command and see if it shows it is mounted properly. Sort of give things a good testing. I would hate for this to come back and bite you later on. I'm not sure if it is grub or not but something is fishy somewhere. Grub has been stable for a long time. Dale :-) :-)

Jacques I wonder if it is a bug or something in the CD you booted? I recently booted systemrescue CD and it worked fine but I didn't try to install grub. I think I used Knoppix for my install. About any of those should work tho. The only thing I can think of is some difference in the file system utilities, kernel the CD uses or something like that. Maybe someone will come along with more ideas. Whatever it is, we do need to figure it out. If it is some sort of bug, it needs to be fixed. Dale :-) :-)

This is because /proc contains info on environment variables and devices mounted, hardware configuration, etc Without it the kernel functionality is not complete and errors will show up sooner or later.
