Tom was right after I changed that I was getting my original windows install coming up but it was crashing while trying to boot. Before changing that I was just getting no boot device found from the BIOS.
No. There is another setting that usually says what mode you have the SATA controller in. Native mode or IDE emulation. Windows won't like it if you have to in a different setting to how you had it when you originally installed and you won't be able to boot like how you experienced.
You've reinstalled anyway so bit late now
