[ug-bosug] Problem with dual booting thumper

[Atul Vidwansa]

Hi,
   I am trying to dual boot thumper in Linux and Solaris. I have
installed Solaris on one of the disks of thumper. The problem is, once
I boot the box in Linux, it refuses to go back to Solaris. Now on
Linux, I could identify the Solaris disk and fdisk shows me following:

[root at thumper ~]# fdisk /dev/sdx
Command (m for help): p

Disk /dev/sdx: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdx1   *           2       60801   488376000   bf  Solaris

But, whenever I try to boot it into Solaris, I get error "Bad PBR
sig!!!". I tried to check whether this disk has boot record:

[root at thumper ~]# dd if=/dev/sdx count=2 | strings
2+0 records in
2+0 records out
M3.0
Can't read geometryNo active partitionCan't read PBRBad PBR sig!!!LBACHS

Looks like even though the disk is marked bootable, it does not have
any active partition?

Is there any way to restore Solaris without reinstalling it?
Cheers,
-Atul
