Windows 7: Cannot upgrade to Windows 10 from WIN7 sp1

Cannot upgrade to Windows 10 from WIN7 sp1

Hi All,
I have tried to upgrade from 7 to 10 at least 6 times and in every instance I get "The Installation failed in SAFE_OS Phase with an error during Replicate_OC operation 0x8007001f - 0x20006" then it reverts to 7.

I have tried to install from a USB stick and using Media Creator Tool then using clean boot, disabled AV etc., and even tried Safe Mode [I know, I know] but am getting desperate. I think I can do a clean install but probably can't do it for free.

Toshiba Satellite L655 P6100 @2.00 GHz 2.GHz with 3 GB RAM, 64 bit Win7 SP1.

It's driving me crazy [which is not long trip]

Any help is appreciated. Tom

You can do clean install for free using gatherosstate.exe.

If you would rather do an "upgrade" keeping settings, etc, it will probably work as a 2 stage process which is a bit tedious

1. do a repair install using win7 installation media ( need to reactivate after)

2. do the upgrade to win10

Just in case you want to do a clean install and updating of Windows 7 SP1 and then do a clean install and activation of Windows 10 afterwards.

Win7 Pro 64bit Upgrade Key w/ Prem 32bit Upgrade Disk
To avoid the Student Win 7 hassle (upgrading Vista 32 to Win 7 Pro 64 bit ISO burn, etc), can I simply use the Home Prem 32 Upgrade (for my other computer) arriving this afternoon with my 64bit Pro upgrade key & end up with the 64bit Pro installation? Thanks.
