solaris boot problem boot error loading interpreter(misc/krtld)

When I installed the SOLARIS 10 OS first time, the desktop would not start up, this was because of network setup. Reinstalled worked. After a week due to some problem I had to reinstall OS, installation went fine and but when i reboot I get this error.

cannot find mis/krtld
boot error loading interpreter(misc/krtld)
elf32 read error
load error read of platform/i86pc/kernel/unix failed.
boot path /pci@0,0/pci-ide@1f,1/ide0/cmdk@0,0:a

I have been trying to reinstall with many option like formatting with windows fdisk, linux installer everything as I saw somewhere that disk needs low level format.

I have googled but could not find any solution..

When I try to format disk using windows this is the information gathered
Partition1 (solarisboot) 12 MB
partition2 unknown 152610

Hardware

pentium4 2.4 GHZ
1Gb DDR memor
Intel Original mother board.
140 Gb hard disk

Installation

install type 3 (tried other options as well)

Entire disk for boot and Solaris
accepted almost all default parameters.

downloaded again , burned a DVD still same.

Any help will be highly appreciated, as I have been trying out everything I could find, also I really want to learn to use Solaris
