No boot device available

[scifiguy1]

Got on my computer and put in a cd that had some audio files on it (Minnesota Wild) archive
audio to be exact.
Computer did not know what do with them, this is an ongoing thing.........
It sat there and tried to read it for a minute or two and still nothing........
So I tried to close" My Computer".
In the background Media player was trying to open..
So I tried closing with the "X: close button at the top right.
Nothing happened on either account.......
A box did come up saying that " The security feature" or something like that failed to start
or something like that also.
I didn`t write it down.....sorry...believe me I am sorry now.
So I went for a restart via the "Start" button ...nothing
just waiting forever with no response from the pc..........
So I powered down and when I powered back up I get this......
NO BOOT DEVICE AVILABLE............
I put in the diagnostic disc and everything checked alright.
I am on Dells website on another computer and have tried all solutions so far..
Computer cannot boot up to go back to any restore point.
What do I do next?
Thanks for your help in the past and I hope you can help me fix it again.

Are you still trying to boot with the disc in the drive? If so, take it out and try again.

What is your boot order in bios?

[scifiguy1]

the boot order is.....
removable,hdd,cdrom,removable..
Things I have tried..............
Cleared Cmos.......
NO help........
It does not see the "C" drive anymore.
It is the "0" sata drive on here....
Now also says...........
"Diskette drive 0 seek failure".........
I have tried unplugging and plugging the hdd.........
YES, I have the power off when I do this..........
I actually work on computers for a hobby.....
But I have never worked on SATA setup before...........
I have never worked on this pc before.
It is my good computer.........OF COURSE!!!
It is a Dell Inspiron 531s.......
Windows Vista Home Premium 32 BIT...
When I said that I was using the diagnostic disk thta is all I was using.........
I have not tried a reinstall of the OS...........
Waiting to see if I can get it fixed first...
I also tried putting the hdd on Sata 3......
It did not see it either..........
I await further instructions..........
I have been trying all solutions off of the DELL website.......
Nothing yet............

You could possibly have a bad cable, I would check to make sure its installed securely. Might also try going to bios and selecting setup defaults, then reboot.
