messed up system

[aconfusedpcgamer]

So I got a new system an OptiPlex 3010 I took it a part and used the guts in my system now it had windows 10 on it, so I put the all the parts in my system I use. I hook up my og hdd and the new one that come with the system my og hdd has win 7 so now the system wants to boot win 7 instead of win 10 it keeps blues screening and launching the system repair, so I check the hdd its fully working I tried the command input system and it didn't work I now opted to try each hdd  by there selves the win 10 hdd booted just fine the win 7 would not boot. so any ideas what's happened to my system ?

Which drive did the system come with originally? Where did the drive with Windows 10 and Windows 7 come from? If you're trying to boot off of a drive that came with Windows installed from another system, it will not work correctly. You'll have to format and reinstall Windows using your new current hardware.

That's why. The Windows 7 install came from another system, which is why it's not booting correctly on your 3010.

I don't know if this applies, but when I rebuilt my friend's computer, I reused the hard drive in the old one that already had Windows on it and it works fine.

Yep. So download and create a Windows 7 through here. When booted into the Windows 7 installer, click custom install and format the partition. Then install Windows on that partition.

It's really hit or miss. I've tried that from Windows XP to even Windows 8 with no luck. Every single time it'll blue screen the moment it tried to boot. (Tested on many Intel and AMD platforms) Other people have reported rampant system instability even though it boots flawlessly after doing so. From my anecdotal evidence, it's just generally not a good idea. Reinstalling Windows doesn't take a long time anyways so just take the time to make sure your system is stable and reliable for years to come.

Windows XP uses IDE mode for the SATA controller. Most PC came with that set in the BIOS by default.
Windows 10 prefers AHCI. Newer machines have this defaulted in them.

That could cause BSOD's with error code 0x00007e or similar.
