Formatted hard drive, downloaded win 10 iso on flash drive The install stops with unexpected error, changed registry value from 1 to 3 on ChildCompletion, the error goes away but computer blue screens. Does the bias need updating. It’s a 2011 machine & it states windows 7 in the bias. ?????
Ive done like 8 reinstalls of Windows 10. Same outcome

What is the product number of your notebook?
Use this guide to find that information...please do not post the serial number.
I'll see if there is a BIOS update available.
You may want to reinstall W7 64 bit and then take the free upgrade back to W10 if W7 will install.
I would not recommend updating the BIOS in any other operating system but W7, since none of them would be supported to run on a newer operating system.

The product number you posted indicates that you have a Compaq Presario CQ57-371SA notebook.
Below is the link to the driver page for that model...the BIOS update can be found under the W7 and W8 driver section.
HP Notebook System BIOS Update (AMD Processors)

You're very welcome.
Hopefully, W7 will install, you can update the BIOS and then do the free upgrade to W10.
You just need to click in the blue Update Now button at the link below to upgrade to W10.
Your W7 installation will need to be activated in order to get the free upgrade to W10.

If you were running W10 on there beforehand, then just install W7 and don't worry about the product key, so you can update the BIOS. I think you have the option to skip entering the key and you can enter it later...which you can't.
Then see if you can clean install W10 as you were trying.
Here is a link to the W7 Home Premium 64 bit ISO download...toward the bottom of the page.
Use the microsoft tool that I zipped up and attached below that you will need to transfer the ISO file to a DVD or USB flash drive so that it is bootable.
After you update the BIOS, hopefully you can clean install W10.
When you get to the part that asks you to enter a product key, select the 'I don't have a product key' option.
