Opensuse 11.1 on usb

Heey,

I have installed opensuse 11.1 on a USB but now I have the problem that it won’t boot correct when I tell my PC to boot from my PC it loads grub loader, right before that I got the messages that it can’t find a file on my second hard drive. but when I installed it I choose to install everything on my USB but apparently it has written something to my HDD so before I try to reinstall I would like to know from someone else what was installed on my second hard drive and how I can prevent that.

I will post the error message later this on here(at school now)
