Boot order is
1. CD drive
2. USB drive
3. Internal Drive
4. Network
Presuming this is a real BIOS system (not UEFI), my wild guess would be:
You have a "malconfigured" grub installed in the MBR (/dev/sda) and a
"configured" grub installed in /dev/sda<boot-partition>.
Should this reasoning apply, marking /dev/sda<boot-partition> "bootable"
(using gparted, fdisk etc.) should help.
