IF I am understanding your post correctly

You had windows 7 installed and for hat ever reason replaced the motherboard then flashed the BIOS and now windows will not start correct?

Hope to hear from you soon,Mike If you replaced the mobo you need to reinstall Windows.I don't have the windows 7 cd but I do have the key Yes that's it ,you got what I was saying Mike.
Good evening hellomotto09 and welcome back

Sorry on the delay

The only way you will be able to fix this is just what I had posted and Allan had said the same thing. Once you make that big of hardware change. Windows needs to be reinstalled, but I do see in your other post that you don't have the W7 disk but you have the key / coa.

If you KNOW of someone that has the same version of windows and same bit version ask them if you can borrow it. So lets say you installed Windows 7 Home premium 64 bit than that is the version that you would need to borrow and just use you cd key /coa.

Hope this helps you if you have any questions please just let us know. Hope to hear from you soon. Mike People losing their Windows CD is a common occorunce around here...
Even those that have an "ahem" version...That's a nasty cough you have there, patio...
Sorry for the delay I got a windows disk but now the disk won't run I don't know how to reinstall when the cd doesn't boot You have to set the CD drive to 1st in the boot order via the BIOS...Well i did do that but it says
"Reboot and select proper Boot Device or Insert Boot Media in Selected Boot Device and press a key"
I dont know what to do Its stressing me out !!!!! On your BIOS setup, check first if the drive is recognized along with your optical drive. Make SURE all cables and power connections are well seated for the HD and cd drive also. Load system default then go to boot priority and set the CD/DVD drive as first. Save and EXIT. Do you have a SATA hard drive you currently? Where is this Win7 DVD from ? ?
It should be bootable.
