Failed four different strategies to upgrade to Win10

Updated windows, Ran DISM restore health, disk cleanup, and did a clean boot, but it still fails @25%

I'll certainly try your method after windows update is finished. Sorry if I seemed irate. I've been stuck dealing with this all day!

Hi xstrike9999

No need to apologise, I know the frustration!

I had tried a few of the items on my list in isolation with no success, except the selective Startup which was a first. It was the combination of all of them that seemed to work.

Microsoft 2nd line support - who were good in the UK on the phone (+44 344 8002400) - stated that between 25% and 37% was when the drivers were being investigated, so I would suggest focusing on the lightest boot possible.

One other thing - When you did the install, did you check for Updates? (I did on my success, although there have been comments from people that have had success selecting no to updates...)

Resized drive C. PC only came with one main partition. Deleted Dell's backup partition which was taking about 20gb. I am booting with the cleanest boot parameters possible but still no dice.
Sfc returned no errors. Here is the CBS log.

Can I suggest you do as I did in post #20.

Boot into you Windows DVD (or USB stick). Install Windows 8 from scratch, format your HDD before the install. You will need your Windows Key at the start of the install.
When the install is complete let the OS activate, will usually do so in a few seconds over the internet.
Then immediately do the upgrade, and select to keep nothing.

That was the only way it worked for me.

Good luck.

Yes, that is the last resort and I'm doing that now. Will update on outcome.

I upgraded using a downloaded ISO, extracted onto USB stick. Worked like a charm.
