BSOD on boot after successful Windows 7 installation

[galapogos]

Hi,

I'm trying to install Windows 7 on a 1TB USB hard drive with Win2USB. The installation completes successfully, but once I reboot and Windows starts to load, I get a BSOD. I've tried the following scenarios:

1. Installation from Windows 7 DVD
2. Installation from existing Windows 7 hard drive
3. Changing to another USB HDD casing
4. Booting up in safe mode

In all scenarios I'm getting BSOD upon booting up.

Here's the BSOD

What's wrong?
