Bootloader problem Grub.

You've got a lot of disks in there! 
It's a bit plainer what the problem is now, hd0 is the wrong drive. grub doesn't use anything like sda, it just uses drives hd0,hd1,etc numbered in the order the BIOS reports them. It might be hd2, assuming the windows you want is the NTFS partitions and not the FAT32 ones. I have no idea how windows will react to being the third drive in the system though! (That might be what those map lines are to fix, not sure.) It might blow its little mind, or it might pretend the other drives don't exist since it can't read their partitions...

grub
grub(5) grub(5) NAME
grub - GRand Unified Bootloader software on Solaris The current release of the Solaris operating system is shipped with the GRUB (GRand Unified Bootloader) software. GRUB is developed and supported by the Free Software Foundation. The overview for the GRUB Manual, accessible at www.gnu.org, describes GRUB: Briefly, a boot loader is the first software program that runs when a computer starts. It is responsible for loading and transfer- ring control to an operating system kernel software (such as Linux or GNU Mach). The kernel, in turn, initializes the rest of the operating system (for example, a GNU [Ed. note: or Solaris] system). GNU GRUB is a very powerful boot loader that can load a wide variety of free, as well as proprietary, operating systems, by means of chain-loading. GRUB is designed to address the complexity of booting a personal computer; both the program and this manual are tightly bound to that computer platform, although porting to other platforms may be addressed in the future. [Ed. note: Sun has ported GRUB to the Solaris operating system.] One of the important features in GRUB is flexibility; GRUB understands filesystems and kernel executable formats, so you can load an arbitrary operating system the way you like, without recording the physical position of your kernel on the disk. Thus you can load the kernel just by specifying its file name and the drive and partition where the kernel resides. Among Solaris machines, GRUB is supported on platforms. The GRUB software that is shipped with Solaris adds two utilities not present in the open-source distribution: bootadm(1M) Enables you to manage the boot archive and make changes to the GRUB menu. installgrub(1M) Loads the boot program from disk. Both of these utilities are described in Solaris man pages. Beyond these two Solaris-specific utilities, the GRUB software is described in the GRUB manual, a PDF version of which is available from the Sun web site. Available in the same location is the grub(8) open-source man page. This man page describes the GRUB shell. boot(1M), bootadm(1M), installgrub(1M) http://www.gnu.org/software/grub 21 Apr 2005 grub(5)
