Background: Windows 8.1 was installed in BIOS mode on a RAID 1. I removed RAID and went to AHCI so I have 2 individual drives. Removed all partitions on drive 1. Drive 0, Windows 8.1 boots OK. Installed Ubuntu from DVD in BIOS mode and installed, made
/home & swap partitions, installed Ubuntu.
Problem: When I boot up the PC, it boots directly into Windows 8.1. Going into BIOS/UEFI menu I can select boot order of disk 0 (windows) or cd/dvd (no disk 1 option) though in a manual boot options I can select drive 1 (ubuntu). If I select drive 1, it boots Ubuntu and I see the Ubuntu boot menu where I can select to boot Ubuntu or Windows 8.1 as part of my boot options. Selecting Ubuntu boots into Ubuntu OK, selecting Windows boots into Windows OK.
Question: How to fix/configure this system so it will offer an OS Boot Option when I do a normal boot?
