In the grub.conf file there must be some entry like
make "default 2" of it. Grub starts counting at 0 for some kind of reason. You have two red hat linux entries because you have two kernels installed. Nothing to worry about.
Things like floppy's and cdroms must be mounted. Actually, all disk and disk-like things must be mounted before you can acces them. Some are mounted automatically on booting (like your root-partition). You can probably mount a floppy by right-clicking on your desktop, and select something like disks, floppy or so, or there is probably a program somewhere that helps you mounting.
If you can't find it you can do it from the shell:
mount /dev/floppy /mnt/floppy
will work most likely. You can find the contents of your floppy after that in the directory /mnt/floppy. Don't forget to unmount your floppy! Note that not mounting when removing can damage the information on your floppy, or make it impossible to take you cdrom out of your computer.
yes indeed, umount. No idea where the 'n' has gone, but it is the right command. If you get an error like "device busy" try
umount -l /mnt/floppy
More information on mounting: type "man mount" in your shell. Also interesting: the list of partitions mounted when booting is in /etc/fstab (carefully when editing! can make your system unbootable!)
Like this you can also mount your windows-partition. Make a directory in /mnt named windows (for example, but you can give it any name) and type in the shell:
mount -t vfat /dev/hda1 /mnt/windows
and find your windows-files in /mnt/windows
Switching easily between windows and linux is impossible: an operating system is too complex for that.
The message when searching google can be safely ignored. There should be some way to put it off in your browser, you just need to find that option
Succes with your new linux
