Error in reinstalling Windows 10

Question

When trying to reinstall W10, the installation fails with error 0x80004005 

I was resetting my Laptop before handing it on to a friend, but unfortunately I went too far and deleted everything.  My Repair disc would not repair the installation.  And I do not have a backup.

When I bought the laptop it came with Windows 8.1, and I was able to reinstall that from an ISO, but doing the same with Windows 10 won’t work.  I had updated to W10 at the time it came out, but of course I don’t have a product key, although I do have a set of 8 X 6 numbers, which I don’t know is for!

Anybody got any ideas?

Hi Mordor1

I am Dave, I will help you with this.

You can reinstall Windows 10 at any time and it will not cost you anything !

You should just clean install Windows 10 rather than upgrading from Windows 8.1. This will have 2 benefits, if you have to reset again, it will reset to Windows 10, not 8.1 and your system will be more responsive and reliable.

Since you previously had Windows 10 installed and activated on that PC during the installation process skip the steps which ask for a product key and select the option 'I am Reinstalling Windows 10 on this PC', and activation will not be an issue, your PC will have a digital entitlement stored on the Microsoft Activation Servers

to download the Media Creation Tool (Click on Download Tool Now), with that you can download the latest Windows 10 ISO (Select Create Installation Media for Another PC), you can create a bootable USB flash drive (min 8GB) using that tool

Then, Boot your PC from the Installation Media you just created (change Boot Order in your BIOS) to begin installing Windows 10

Thanks Dave, this worked, after I had problems with Partitions!

Answer 3

I'm sorry if the steps didn't work. It seems that the issue is complex than what I expected.

It may be best if I release your question to other advisors so they can take a look at it and let them share some other ways that can fix the issue.

You take care and keep safe always.

Sincerely,

Louie

Answer 4

I'm afraid none of these helped me. To be clear, all I had was my Laptop repair DVD, which had, I presume, Windows 10, which would not repair, and a Windows 8 ISO which I was able to use to restart the formatted laptop.

So I cannot get any installation of Windows 1o to load.

• Have run sfc scannow, no problems
• Run Update Troubleshooter which fixed two  issues
• Ran Windows10Upgrade9252.exe from USB and it  failed again at 80%
• Ran Update Troubleshooter again, and once more it said it had fixed the same  two issues
• Tried installing with Media Creation Tool to update; failed.
