Boot from a rescue CD, and use restore from that on your old root disk
mounted locally. This is part of the old "bootstrap" problem. You need
some sort of bootable tool, not booting from the / partition, to allow
you to actually *install* the / partition.

In which case your tape may be screwed: I'm not familiar with that
issue, but it raises a question.
Why are you using dump/restore when the ext2/ext3 file systems with
modern Linux kernels face a risk because dump talks to the blocks on the
disk, but not all files have necessarily been written to disk yet: they
may be cached in RAM.
In the future, I urge you to use tar: it's nearly as fast, and a lot
easier to configure.
