I have a Dell T3500 workstation with v. A17 BIOS, and it runs Win7 Pro. It came with just 1 HDD, but it was set up with "RAID On" as the SATA Operation setting in the BIOS. I have added an SSD that is still unformatted, but the fact of there being 2 SATA drives now causes a splash screen to appear during POST that announces "RAID volumes: None defined". Since I never intend to set up a RAID system, I wish to change the SATA Operation setting to "RAID Autodetect/AHCI" so that the screen never appears and there is no RAID overhead. But with that setting, Windows starts to boot, then it freezes.
My intention is to clean-install Win10 Pro on the SSD, and I understand that if I do that with SATA Operation set to "RAID Autodetect/AHCI", the resulting POSTs and Win10 boot-ups will go smoothly. But if I do that, I will also not be able to boot Win7 Pro on the old HDD if I should need it.
Is there a way to set the old Win7 Pro to boot up if the SATA Operation setting in the BIOS is changed to "RAID Autodetect/AHCI"?
