I have a DC7800 Ultra Slim desktop. It only boots into the blue BootBlock Emergency Recovery Mode screen. I've burned the bios image iso onto a CD and it picks it up and says it's flashing the bios. Then it says to unplug the machine for 5 seconds and plug it in again. When I turn it back on, it ends up in the same recovery mode screen. I've done this at least 25 times and I've tried all the versions of the BIOS on the support site. I've also tried putting the bin file on a USB drive, which the recovery mode finds, and flashes, but it still only boots into recovery mode. I've tried using the CMOS reset button, and setting the Boot Block jumper, but nothing helps. Is there anything else I should try, or is it dead?
