Apologies if this subject has been discussed to death before, but I'm getting nowhere with this:confused:

My dad wants to upgrade his Win 7 Pro PC to 10 before the deadline, fair enough.

So last night I installed Win7 on my m-ATX box. The machine hadn't been setup properly since I cobbled it together out of spares and the SSD had a borked Windows install:

CPU: G3258
RAM: 16GB
GFX: 750Ti
Motherboard: Asus Z97M-Plus
PSU: EVGA GS 550W

Win7 installed fine and I then installed the motherboard and graphics drivers so I could get online. So I try running Windows Update and of course it refuses to play ball. Instead of sorting it out, I thought 'screw it, I might as well update directly to 10'.

So today I run the upgrade assistant. It's downloaded and then gets to installing. After watching it get to 99% complete I thought it would just finish. Nope, it's currently been at 99% for about an hour. I assume the only course of action is to just leave it and hope it'll finish? Or do I give up, reinstall Windows again and try to sort out the Windows updates first?

I've read that some systems have taken 20+ hours to finish, some not at all.

My main PC is not getting upgraded from 8.1 until I'm forced to.
 
I've had it stuck at a percentage sometimes 99% for upto 6 hours before completing before :( or got to about 6 hours and still not completed at which point I got fedup and restart it after which it rolled back and then tried again and completed successfully the second time. Windows 10 is a shambles.
 
Thanks for reading my post, it was a bit of a rant!

When you say restarted, did you just do a hard reset or a Start Menu restart?

The main thing here is that it's a clean Win 7 install, so it's not up to date. My dad's PC has no issues with Windows update, but I'm loathe to upgrade it until I've got an idea of how the process works in case somehting stupid like this happens.

I live 40 miles form my parents, so I can't just nip home to sort things out like I used to!
 
I've had a couple of instances of it stuck on 99% from the actual fullscreen (not inside Windows) installation where I've just done a hard restart - on restarting it rolls back to previous install and then on the subsequent attempt it has taken. Also had similar on updates.

I've found for older people especially its is better to leave them on 7, disable updates :( (due to so many issues lately plus the chance of auto upgrade to 10) and make sure their browser, AV and firewall are kept upto date - many of them get used to doing something a certain way often with notes written down for the exact path to do stuff and Windows 10 has a habit of changing everything around on the bigger updates and confusing the **** out of them meaning I have to spent a lot more time supporting them.

OK, thanks for the input. It's on the Windows upgrade assistant within Windows right now. I reckon I'll gamble on doing a hard reset and see what happens. Worst it can do is corrupt a clean windows install - this system has nothing else on it! If all else fails and the reset borks it, then I'll reinstall 7 again, get it updated (if possible) and then try again.

I need to get the upgrade complete so I can do a clean Win 10 install. ATM my Win 7 serial isn't registered for Win 10 - or at least that's what I'm led to believe.

I'll update this thread with the outcome of my wranglings!
 
Right, the hard reset didn't break anything. The Upgrade Assistant is now re-downloading and installing. If this attempt doesn't work I'm going to try the Win 7 Convenience Roll-up next to try and get 7 into a more up-to-date state in case that is what is causing such an issue.
 
Just had this happen on a new win7 dell. Took about 5hrs at 99% before it moved on. 1st few times, I restarted but had to start the upgrade from scratch each time so ended just leaving it.
 
OK, the convenience rollup (CR) has 3 prerequisites other than SP1 - two small Win Updates and the April 2015 servicing stack upgrade. Once these are done I'll get the CR done.

At the very least, at least I'll have a more up-to-date Win 7 system. If it still hangs up on 99%, then I may try to leave it running overnight. At least the fans are quiet enough that I might be able to sleep with it running.

I thinking I may dig out a spare 240GB SSD and 1TB HDD and clone my dad's boot and storage drives. At least if everything goes crazy when I do his system, I'll have a plug in replacement!

Edit: Now using WSUS to update to current Win 7 build standard...hopefully!

Why not download Windows 10 to either a USB stick or a disc, backup any files that you need to, then install Windows 10 from fresh? I'd imagine it'll take about 10 minutes to create an installation on a USB stick, another 10-20 to boot up from the stick, format the entire drive then reinstall.

The hardest part after that, is configuring the drivers and Windows.
 
I would create a USB image. The only problem is that as far as I know, you need to run the upgrader to "register" your licence key with Win 10. Otherwise I'd be very, very happy to do a clean install.
 
Finally! Got there in the end. Once the WSUS Offline updater (version 10.6.3) finished, Windows Update came back to life. The upgrade assistant then had no issues whatsoever installing Windows 10.
 
Had windows 10 update fail 6 or 7 times, only got it to install after I turned off windows update by setting it to never check for updates.

It may have been luck but it did work first time after I turned off auto update.
 
Tried that, still didn't work. In the end the WSUS Offline updater did the trick.

I always have auto-update disabled. Sure I let it check for updates, but nothing gets installed without my permission!
