By loading I have received the following issue: BAD PBR SIGN.

Hi folks.
By disk cloning on Solaris x86, I used a command dd.
I pulled out the source and inserted the new disk.

which "dd" command did you run?

e.g. # dd if=/dev/rdsk/c0d0s2 of=/dev/rdsk/c0d1s2 bs=128
then issue: ****+1 records in
****+1 records out

Bad PBR sig after Solaris 10 x86 installation
this should be a filesystem issue...

This command apply to SPARC hardware. On x86, it doesn't copy the primary boot loader (thus the error message Bad PBR sig= bad primary boot record signature). You should have used that command to copy the whole disk:
dd if=/dev/rdsk/c0d0p0 of=/dev/rdsk/c0d1p0 bs=128k

Note that bs should be in kilobytes unlike your sample code.

Another point, cloning a disk while the OS is using it as its root filesystem is likely to create a corrupted filesystem on the target disk.

I have tried to make as you suggested.
On a new disk has appeared x86 boot and the system is loaded!!! in Solaris Device Configuration Assistant and ask me every time which disk? I choice the disk (at this time to mainboard connected only new disk) and the system goes only in single user mode.
