You should always install grub on the first bootable disk - even if it is
the windows one.

It took me a while to understand the problem. Try partitioning the new disk
(sdb) into one smaller partition for boot (1GB) and the rest for root.

Install grub on sda, because your bios is setup to boot from sda.
Alternatively change bios to boot from sdb and install grub on sdb - this
way you can go back to sda in the bios if you fail.
