Ubuntu 8.04.2, just installed, doesn't allow access to my hardDisk.

[David MacClement]

An hour ago I downloaded and installed Ubuntu 8.04.2 while using my
8.04.1, but now I find that neither my own hardDisk nor my earlier
installations (e.g. with their Firefox bookmarks) are accessible to me.

How do I either:
1) find those other partitions (there used to be a command-line-style list
in a box, just after start-up)
- or:
2) remove (de-install) 8.04.2, leaving my computer as it was before.

I still have my CD with the 8.04.1 ISO, and wonder whether I should
install from it (losing the space taken up by this 8.04.2). That would be
better than having no access to my fifteen-years-worth of files and
folders on my hardDisk.
