My bad. Sorry.

Carlos already corrected this, and Patrick added next important file. 

The /dev/sda2 is marked active.
If generic boot loader is in /dev/sda MBR, and grub is installed in /dev/sda2 
boot sector, it should pick up and boot from there. 

So we looking:
- is generic boot code in MBR of /dev/sda
  dd if=/dev/sda of=sda-mbr bs=512 count=1
  strings -n 10 sda-mbr
Should give this:
  Invalid partition table
  No operating system
  Error loading operating system

- is GRUB installed in /dev/sda2
  dd if=/dev/sda2 of=sda2-mbr bs=512 count=1
  strings sda2-mbr
It should list in last lines:
  GRUB
  Geom
  Hard Disk
  Read
   Error

You can try tests on /dev/sdb and /dev/sdb1.
