The history of the matter is this, he created two new drives, sdb1 and sdb2 in sdb, on top of them recorded two logical volumes lv1 lv2. Then the fdisk command and then o . Erased the division table on SDB, thereby destroying, сдб1 and сдб2, and then began to remove the logical blocks. After that, SDI created the two new сдб1 and сдб2 сдб1 did the swap ω and remontiroval it. Then shut down the system. Now can't boot. Bootloader hangs before asking for the password.
