 sorry, i can't.
 
 I describe more in detail, hope this might help.
 
 
 DOS (primary) partition #2 is where i tried to install NetBSD-4.0. DOS
 (primary) partition #3/#4 have "FreeBSD 7.0-STABLE i386"/"FreeBSD 7.0-STABLE
 amd64" installed respectively. Boot manager is Grub came with linux
 system.
 
 After NetBSD-4.0 installed, linux said::
 
 -- linux's /var/log/messages --

 At this point, Grub cannot boot from neither DOS partition #3/#4.
 
 If I remember correctly, the corrupted disklabel had 'c' and 'd'
 elements were existed correctly (in means of NetBSD), other 'a', 'b',
 'e' and 'f' elements were erased (not 100% sure, sorry).
 
 After recovered label (by hands)::
 
 -- linux's /var/log/messages --

 And disklabels of freebsd on DOS partition #3 (it might be same as
 originally installed because of hand repair)::
