A couple weeks ago, I decided to finally uprgrade my system from windows 7 to windows 10, via the online free upgrade. After 2 weeks, I decided that I preferred Windows 7 and saw the option to revert back. I followed the prompts to do so, but when my computer attempted to reboot, I got the "Windows Error Recovery" screen. I tried the startup repair, but the system said it was unable to fix the problems, at which time the "HP Recovery Manager" screen popped up. I tried to use the system restore feature, but it said there were no restore points created (I created one before upgrading to 10).
Since then I have tried to reboot several times, but just keep going in the same loop.
I also tried downloading the Windows 10 ISO file and boot from my USB, but that did not work either. Microsoft said at this point I should contact the manufacturer (HP), who of course said that my computer was no longer under warranty. Any suggestions?
My computer is a HP Pavilion dv6
Thanks for any help you can offer!
