I have the DP55KG motherboard that's been in my self-built system since 2010 and has had Windows Vista Ultimate x64, Win 7 Ultimate x64 & Win 8.1 Pro x64. It's been flawless except for one consistent issue: It will not boot to a USB drive/stick or a DVD drive, not matter what I've tried.
I've built a lot of computers and tinker with them all the time and am pretty well versed in configuring them properly. I've done the usual BIOS updates, configured the board for USB or DVD boot, etc., etc., over the years to test variations for getting it to boot to USB/DVD...but nothing has ever worked.
When I create the usual recovery USB sticks or other utilities that are common, my computer will not boot with the stick plugged in.
Nothing I've tried has EVER got a USB stick to boot.
This same issue occurs if I try to boot from CD/DVD, such as using the Windows Vista, 7 or 8 install or recovery discs., with one exception:
Recently, I've been downloading & installing the preview builds of Windows 10 via the MS Insider Program. This same motherboard issue is also present when trying to install the ISO via DVD or USB on to a completely different hard drive connected to this motherboard. During this, my Windows hard drive described above was disconnected because I keep them separate from the Windows 10 install hard drive (When I want to tinker with Win 10, I pull my Win 8 drive and connect my Win 10 drive. I do this on purpose because of early 10 builds that others reported corrupting Win 7 & 8 system drives that were concurrently connected).
Note: All motherboard USB ports, external USB hubs, and all internal or external DVD drives work normally once Windows boots & loads. I don't have any defective USB ports or connections.
This has been a very frustrating problem because it prevents the usage of any USB sticks for booting to ISO's or recovery tools, or system images on large USB drives. The workaround of disconnecting all drives to get a DVD boot is a band-aide solution that doesn't workaround getting usage of USB booting.
I've searched all over for any resolution to this issue, but have found none. Does anyone have any idea why this occurs and how to resolve it?
Kevin...you're kidding, right? I stated, in the second paragraph, that I've gone through setting all of that in the BIOS, many different times with no luck.
Please provide me with the following:
Dxdiag Report: Type dxdiag in Start Menu> open> Save> Attach using Advanced Editor Options.
System Information: Click Start> Type System Information> Click File> Export> Save File> Attach using Advanced Editor Options.
I will set this lab and verify from my side with this board.
Attached are the two reports you requested. I haven't checked, but I think I've turned off USB boot and DVD boot after the last attempt, since it was useless. It just goes straight to the hard drive for booting. I have another rig with the Intel Extreme board D975XBX2 (the BadAxe) that's been running for years without issue and will boot from USB/DVD when I set it in the BIOS. But this DP55KG has never been able to do that, no matter what I set in the BIOS. Hopefully, you can spot what the issue is and have a solution.
I have tested this same board from my side and I am able to boot to USB devices or external ODD. I tested this with the same board model running BIOS 5936 and it is recognizing all devices in the BIOS and as mentioned before, I am able to boot to those devices.
I know this may be very basic but it is necessary to press the F10 key to get the boot options and select the bootable device.
As mentioned before, from my side it is working just fine so I think you should contact our support center for further assistance.
