Installing os (non EFI graphics card)

[rdsii64]

My 3.1 Mac Pro ( I know it’s acient but money is tight and it still works)
Works fine and has no problems. It has a non EFI HD5770 that works fine for what it is.
Do I have to do anything special since I don’t have a boot screen, if I want to do a clean Install, or maybe dual boot a second os. I don’t do anything critical with machine.

Depends on your OS version. Recovery partition should work with non Mac EFI card (as long as it has native driver support). You can simply boot into recovery partition and then format the hard drive and make a clean OS install at there.

For Windows, you can simply boot from a disc, your GPU will work (even non natively supported card), and install Windows just like on normal PC.

Also, you can boot from any backup drive, and then format / re-install OS to the primary drive if you want to.

Thank you. That doesn't sound to difficult. I as unaware I had those options.
Again, Thanks.
