Can't load Windows with the "Error 0x800703f8"

Evening partygoers,

So went to start up the ole pc and I received the "no bootable device, please insert blah blah blah"
Soooo put in the Win 7 ultimate disc and the computer does nothing except take me to the main Install Windows 7 page. I have clicked on "repair my computer", I tried 3 different restore points and those were a no go. I performed a chkdsk and a chkdsk /fC: and it came up with nothing.
I do not know if it has anything to do with the MBR so I didn't go that route (yet). Also Startup repair does not work as well. I can enter "safe mode" but all it does is take me to the Windows 7 install screen. If I try to "start windows normally" all it does is just take me to the windows 7 install page as well.
My device is an i5 with 4gb of RAM, the basic standard stuff.


UPDATE:

I have put my hdd in a different drive and it works fine. audio/video files (my main concern). I am running a malware bytes scan and AVG anti-virus scan now.

More news on the homefront: malware came back with no issues and AVG picked up 2 java virus'. I had the AVG take care of the virus situation.

After putting my hdd back into its original computer the hdd is not being recognized. I guessed that this might happen. Keeping the updates coming so hopefully the symptoms will narrow down to the problem in hopes in can get resolved.

Hi,

Try to change the cable you are using to connect the HDD to your mother board. As you mentioned that this hdd is working fine on other PC.
