You scare me installing Linux from Win
<quote>I couldn't install linux from the CD, because it didn't seem to find it</quote>
Who couldn't? Your computer? You couldn't boot from a bootable (install) CD?
OK. You have Linux.
/etc/mtab lists what is mounted
/etc/fstab lists what can be mounted
Is the CD /dev/cdrom or /dev/something_else?
<quote>I mounted it correctly.</quote>
What did you do different here? Do it again, no?
