Hello Shao

thank you for your attention and time.

your are completely wright again!

It's my fault, pitty on me, mbr-sys is ms-sys (ms-sys.sourceforge.net)
ms-sys -z fills MBR with NULL, but "parted mklabel msdos" produces new MBR, than "parted set 1 boot on" updates MBR with default value for the first partition.
This sequence works on almost every hardware except those with HP RAID controller, where Illegal Opcode came
