IDE drives problem

[matrixgaby]

I just installed the new Windows 7. Until I deconnected my second HDD, a 120 GB IDE does not wanted to install. Now when is installed, I reconnected the second HDD. When turn on the windows, it´s not seen and my second DVD-RW, which is IDE also is not seen.
Also none of those 2 is not seen is the BIOS.At startup it hangs 30-40 seconds, freezing, before displaying BIOS Post message notes.
Before Windows 7 I had Vista and all was working fine.
Please excuse my english, i´m not american.
What can I do? Please, a hint to sove that.

Check the jumpers on the back of the hard drive / DVD drive, make sure one is set to master and one set to slave.

I hope this helps because i really don't know what you said forgive me!!
