unbootable solaris 10 x86

Hi all,
I have unbootable Solaris 10 x86 installed on ZFS root file system. on an IDE HDD

The bios keep showing the msg

DISK BOOT FAILURE , PLEASE INSERT SYSTEM BOOT DISK
please note : the HDD is connected properly and recognized by the system
is there any guide to recover the system , or detail procedure to boot system again
Thanks,,,

That's a BIOS error; your computer is not finding anything to try to boot from.

recognized by the system

What makes you say that?

Try reinstalling grub to the MBR.

I tried to install bootblk
with no luck

i ran

PHP Code:




#installgrub /boot/grub/satge1 /boot/grub/stage2 /dev/rdsk/c0d0s0 
connot open/stat device /dev/rdsk/c0d0s2

here is the output of fdisk

PHP Code:




#fdisk /dev/rdsk/c0d0p0
