Hard drive 1: 250GB SSD running Linux Mint 17.1
Hard drive 2: 480GB SSD running Windows 8.1 Pro

From a live cd I've mounted my Linux partition and installed grub2 on the first hard drive. On reboot I'm greeted with grub2 with these options:
Linux Mint 17.1

Linux Mint 17.1 Recovery

Memtest

Windows 8 (loader) on /dev/sdb1


Choosing Windows 8 gives this error:

error: no such device: *serial number*
error: hd1 cannot get C/H/S values
error: hd1 cannot get C/H/S values
Press any key to continue...

I can boot to Linux Mint without issue. I've run 'sudo update-grub' which does allow me to boot to Windows, however, this will sometimes work for 1 reboot only. During my troubleshooting I did install grub on the Windows SSD as well. How can I clear the boot loader from both drives and start over? I would like the Windows 8 option from grub to work every time.

I understand that there are Windows utilities that will restore Windows boot loaders. But be careful it does not put a Windows boot loader onto both disks. I am certain that will happen.

I do not support Linux MInt. I will tell you this. When we have a machine with Windows 8 pre-installed we need to follow this advice.

Moved to other OS.

Best to see details. Post link to summary report.
With 2 drives do NOT run auto fix. That just installs grub to both drives and we do not want that.

Boot Repair -Also handles LVM, GPT, separate /boot and UEFI dual boot.:
Current version ppa now available.
