Comment # 2 on bug 1094834 from Stefan Hundhammer

From just that screenshot it is impossible to tell what exactly hangs. It might
be during hardware probing; the usual "safe mode" and ACPI parameters to start
the installation media come to mind. Also, please make sure the checksums of
your media (SHA256SUM / MD5SUM) are correct; this is a common problem.

In general, Lenovo T4xx laptops are known to work well with Linux; they have
unproblematic hardware (Intel chipset / Intel graphics), and lots of Linux
developers use them. It is somewhat surprising to hear that this kind of laptop
causes problems during hardware probing.
