grub error 25

[Daryl Styrk <darylstyrk@gmail.com>]

Hi list.. I was attempting to direct the debian installer to /dev/sdb1
a flash drive.
I am now stuck with a broken system and don't know where to go from here.. I
am posting this from knoppix.  I suppose I need to edit something in
/boot/grub/
but I don't know exactly what..

Here is fdisk -l

Partition table entries are not in disk order


I don't know why two partitions are flagged at boot..

I would appreciate some help to get up and running again.
