Hello all,

I have this grub.cfg:

I do not see anything.
The problem I'm having is that whenever there is an usb (non-bootable) drive attached to my system, grub detects it as hd0 and the hard drive in which I have the OS installed is named as hd1 and thus grub can't find the image to load ( the boot order is correct on the bios.). When there is no usb attached the hard drive is named as hd0 and everything is fine. Now, I know I could solve the issue by using "search" but I'm really confused here, because I thought that the current harddrive loaded by the bios should always be hd0, so I'm not sure what is happening... Is there a way to make grub to always set my HD to hd0, so that when the usb is added it is set to hd1?

No. hd0 it the BIOS drive 80. Whatever BIOS assigns this number to.
