Installed Haiku; and the computer just doesn't boot it.
I have 2 hard drives. On one, there is a partition for Windows; and another for files.
The other hard drive had only one partition, for files. I created another one for Haiku; and installed it on that one.
I chose "Haiku's" HD, to boot from; and it didn't do so. Than disconnected the other HD; the same.
It acts just like there's no operating system; other than Windows.
