After changin mother board and video card = Hard Disk boot fail?

Question

Hello, here is the story:
Not long ago one of my PCs crashed, so I deided to use this opportunity to update my other PC using some of the first's hardware. So far so good. I kept the motherboard, changed the processor, changed RAM and I changed the vido card. I also added the hard disk of the PC tha broke down to the other two on the still healthy PC. Meaning that now it has 3. I got all the wiring done correctly and checked for campatibility issues.
I turn on the PC (with all 3 HDs connected to the motherboard) and get the following message: Hard disk changed, boot priority will be effected, go to Setup. Ok, I do that, I check that all booting should be done from a Hard (Keep in mind that that means that there are now two OS total) and expect to get a screen winth "Choose which OS to boot up. You have x seconds left..."but instead it tries to boot from a CD and tells me to insert an OS disk. with something like this "Disk boot failure insert OS and try again"
I also tried doing with with each of the OS carrying drives turned off seperately, but it still won't work.
Any ideas on what I might be doing wrong?

so which you only decide to start over with the aid of reinstalling considering you are able to no longer restoration the difficulty from secure mode? Formatting is a pre-setting up technique that prepares a disk to recieve archives in a definite organizaional shape. (fat or NTFS) it truly is computerized. All you may do is %. one whilst your set up application asks you. in case you do no longer decide to lose something you have saved on the gadget that "refuses besides", you may study the thank you to restoration regardless of brought about your undertaking from interior safemode.

Thats because it dont' have any of the new drivers loaded. Its still trying to load the old hardware configuration. You did plan on this and were ready for a re-install of everything right???
