|What you describe indicates you have lost your master boot record. Usual solution is to boot into recovery console and run the utilities fixmbr and fixboot. Exit and reboot. See if you come up normally.|
Always scan your downloads before and after expanding them.
It would also appear to me you used the firmware upgrade for the 832s on the 182S.
Firmware updates are only for your model. These are two different models.
Also don't you mean 812 not 182? I find no model of 182
firmware for 812
firmware for 832
