Can't upgrade Windows 7 to Windows 8 - registry error

2

I am upgrading my Windows 7 setup (dual partition, one hdd), and I got this

Windows could not update registry data, cancelling install

And the setup is aborted, leaving an undeletable $UPGRADE.~OS and a windows.bt folder

What can be the problem?

Have you tried running a registry cleaning utility like cccleaner? – Caleb Jares – 2012-10-30T00:54:23.040

I did mydefrag, scandisk, ccleaner and the full surface scan utility from western digital – Magnetic_dud – 2012-10-30T11:07:43.153

This is sometimes the result of 3 things:

  1. Windows rot (often updates will screw things up)
  2. Registry cleaners
  3. Bugs with MS software (You may have found a bug with the Windows 8 installer)

I would strongly advise you to do a clean install.

I opted to wipe the drive and do a clean install – Magnetic_dud – 2012-11-01T11:32:09.453

Have you ever messed with any registry key permissions? I recommend you back up your personal data, use the Upgrade Assistant to create USB/DVD (ISO) media, then boot from that and clean install Windows 8.
