My computer uses the BIOS (MBR) system for partition management, not UEFI. I read a TrueOS Install web page that showed an Advanced option where MBR could be selected. However, I did not see that option up to the point where I had selected the partition and the installation would begin. At that point, I decided I needed more information to proceed. So here I am, hat in hand.
I sure would appreciate some help, because I want to use TrueOS… but I don’t want to lose access to the other systems on my hard drive.
