    Windows 7 Pro to Windows 8 Pro Upgrade won't complete


    I have a custom-built PC with an Asus P5Q Pro mobo, Intel Q9550 Quad CPU, 8 GB Ram, Asus Radeon HD 4870 graphics card -- single monitor, with nearly 400 GB of hard drive free space running Windows 7 Professional sp 1 64-bit.

    I ran the Windows 8 Upgrade Assessment tool and other than telling me that I would need to get a DVD player and my gadgets would no longer be available it did not identify any issues. I clicked next and it suggested I upgrade to Windows 8 Pro. I clicked next and purchased the upgrade and downloaded the install file. That was the last thing that worked.

    It goes through the installation without incident until it gets to 65% of setting up devices. Then it says that it encountered an issue that prevents a successful installation, suggests that I research DPC_Watchdog_Violation, reboots and rolls back to Windows 7. I can find nothing that approximates a setup log file that would give me any more information about what the issue was. If you google DPC Watchdog Violation it doesn't take long to see that it's a very common thing and the only thread that was marked as "solved" didn't say what the solution was.

    After trying a few things suggested by some folks on the Tom's Hardware forum, including trying a completely different graphics card, I gave up and called the Microsoft Answer Desk. A guy spent an entire day uninstalling things like Norton, non-MS browsers etc and having me disconnect all attached devices. It never changed a thing. 65% and boom, roll back. Every time, no matter what he did.

    He then escalated to a more technical support tech who spent the next day doing essentially the same as the first guy did but also uninstalling devices and using Revo Uninstaller to clean my PC of just about all of it's apps. Still, not one iota of difference. 65% and boom, roll back. Both of these guys lamented the lack of a log file that would give them any information about what the issue was.

    They ran out of spit and ended by telling me that it was a common problem and that lots of people were experiencing it and they expected a fix from MS just about any time.

    So I was surprised to not find any threads here describing a similar issue. I looked in the general discussion areas as well as here and if others are experiencing this same problem then I must have missed it.

    Does this sound familiar to anyone? Especially anyone that knows how to fix it?

    Very frustrating...

    Yep, I just had a failure at 98%.

    Will have a good dig and see if there is a hidden log somewhere

    It should be here:

    %systemdrive%\$WINDOWS.~BT\Sources\Panther\setuperr.log

    I had this same exact issue. The only thing that worked for me was to select the "keep nothing" option. Which deletes programs, settings, and user data. I backed up my data, installed windows 8, re installed my programs and put my data back on. Probably the best option for me

    My machine has lots of applications on it. Just the thought of having to reinstall and update them, assuming that I could even find all of the setup programs and purchase keys, is enough to keep me on Win 7.

    @SIW2: The system automatically rolls back to Windows 7. Will the Windows 7 setup error log file still be there afterwards? In your case, was the log file helpful? Have you got a successful upgrade yet?

    Surely this is something that is a big enough deal that MS is working on it as we speak. Surely...

    I don't want to mark this as solved because I was never able to get the upgrade to work. Perhaps there should be a way to mark the thread as cancelled or closed without resolution.

    I think something so fundamental as an upgrade process should #1 work and #2 be well understood by the MS techs. Neither of these are true in my case. I've decided not to spend more than the 3+ days I've already spent on it.

    I just called Microsoft and had the order cancelled and my purchase price refunded.

    Thanks all for trying to help me.

    The same thing happens to me but I get all the way to choosing the color scheme and then it asks me for my Microsoft account number but then cannot find it, so I skip that to enter it later so it goes to finalizing settings screen for 5 seconds and then I get a black screen. It has been four hours now and still black screen but the hdd is still working away so I will wait a while longer. I have about 2 terabytes of data so I am hoping that this is because of this that it is taking so long. I will let you guys no what happens.
