re edit grub boot loader

[cv65user]

i had dual boot=

 

160gb

primary, ntfs, 20gb, xp pro spk3

logical disk

logical, ext3, 4gb, opensuse <<-hd0,2

logical, swap, 1gb, linux swap

primary, ntfs, REST, data partition

 

 

i now made and moved all the following partitions down one to accomodate max osx so now its:

 

160gb

primary, ntfs, 20gb, xp pro spk3

hsf+ partition, 10gb, mac osx

logical disk

logical, ext3, 4gb, reserved for knoppix

logical, ext3, 4gb, opensuse

logical, swap, 1gb, linux swap

primary, ntfs, REST, data partition

 

now grub boots to error 17 as its looking in hd0,2) partition. but there is nothing there as its now the knoppix partition.

 

1. how do i edit grub?

2. should i be point grub to the hd0,4 partition right?

 

the pc is aspire one so i dont have dvdrom drive. i will need the closest and smallest grub distro that i can put on usb stick to boot from
