If you had, as part of the installation, it would be working right!

With your totally crappy attitude, you don't really deserve help, but on
the off chance that you might not be trolling, and are just frustrated,
I'll make an attempt.

Take a deep breath, calm down, and pay attention.

First off, grub is doing exactly what it's supposed to do, and is working
fine. Grubs only job is to find the kernel, and initrd, load them into
memory, and tell the kernel where you say the / partition is. Once the
kernel is loaded into memory, and starts the boot process, grub's job is
done. Your problem is finding out why your kernel is panicking while
trying to load your OS.

You say "/boot is indeed /dev/sdb1", so the question I have is where is /?
That is what grub wants to know too. If you tell it where / is, it will
probably boot up just fine.

### Print this out, so you can follow this exactly from Knoppix ###

Boot your Knoppix disk, log in as root, and in a terminal, type;

# fdisk -l /dev/sdb > /root/test.txt <Enter> (Thats the "Enter" key)

then type;

# mount /dev/sdb1 -t ext3 /mnt/ <Enter>

# cat /mnt/grub/menu.conf >> /root/test.txt <Enter>

# umount /mnt <Enter>

# mount /dev/sda1 -t ntfs /mnt <Enter>

# cp /root/test.txt /mnt/test.txt <Enter>

You now have a file named "test.txt" in the root directory of your Windows
OS. Shutdown Knoppix, reboot to Windows, and post the contents of
"test.txt" back here. You can open it with notepad, and copy/paste it into
your newsreader.
