There is no need to reboot the real machine if you use Virtualbox (I
can't speak for other virtualization software). However your admin would
have to install Virtualbox on your machine. Then you would install
Ubuntu from the ISO file of the Ubuntu live CD. You would install it to
a virtual disk which is a single very large file (at least 4GB) on the
real hard disk. As the virtual disk is only a large file it may be owned
by you and you don't need direct disk access on the real machine. But on
the virtual machine you are the main user who has root access. Then you
can analyze the file system within the virtual disk. And if you reboot
the virtual machine you don't reboot the real machine.
