I just got an Asus p5q se plus and it will not boot to windows.

I tried 2 different drives with windows 10 and it does the same thing.

I tried all 6 different sata ports.

I messed with bios and nothing changed.

I have a xeon x5450 with a 771 to 775 conversion, 2gb ddr2 and a gts 250.

everything esle works like the drive and power supply but have no idea why it can't boot.

Does it have to be lower than windows 10?

I'm just stuck on the Windows 10 loading screen without the circling dots and.. well now it says preparing automatic repair but it's been there for 10 minutes because I can't think of anything else.

Another fellow found the hard way recently that Win 8 and 10 require the Xeon microcodes in the BIOS in order to boot such a conversion. This would be particularly likely if your E5450 is an early C0 stepping SLANQ.

When chips are first released for sale they come with embedded instructions that may include errata. Like software nowadays which is shipped in an unfinished state to be patched later, the updates (called microcodes) are shipped to motherboard manufacturers to include in their BIOSes, but they wouldn't have included Xeon microcodes from the factory. Did you flash a BIOS with Xeon microcodes to your P5Q SE?

Well your socket 775 system does not support UEFI boot, probably doesn't even know what to do with GPT partition.

You cant just move windows installation from system to system. First of all this is a violation of your windows license.
Secondly of all windows is installed for the specific hardware in that system, when you move it to a different computer it will typically at best be unstable if not completley fail to boot.

You need to do a full reinstall of windows if putting it into a different computer. You also need to have 1 windows license per computer, you cant hot-swap drives around to say have 4 computers and 1 valid windows license

Yes - sometimes it works, but it's more of an exception than rule.
For it to work always, you'd need to swap drives between computers with completely identical hardware
(and with identical BIOS settings). And even then, you'll face problems with windows activation.
