I have a dual boot system Win98SE and Linux and had initial problems 
installing redhat 7.0 on the linux partition (using lilo as boot loader). 
During the installation (tried for both GUI and text mode) I mounted the 
vfat partition using /mnt/drive_x and this is what i got.

I retried leaving the vfat partition unmounted and proceeded with the 
installation. When everything was finished I just remounted the same vfat 
partition using the mount command and I had no more problem. This bug 
(although there is a workaround) can be discouraging for newbies.
