Had gotten the message from Microsoft that my laptop could upgrade to Windows 10. Did so on 7/29/2015 and things seemed ok, but it was very slow and wireless mouse's scroll wheel didn't function. Then bluetooth stopped working. Ran the program to go back to Windows 7 and it said it completed properly, but now it won't boot. Can't go to safe mode and when I looked there are no recovery points saved. Even though warranty has expired, Dell support agreed and sent me "Reinstallation DVD" for Windows 7 Home Premium SP1 64-bit. My problem is that I really don't want to do factory reset type of install as we have thousands of photos on this laptop and they can not be replaced. Any help would be appreciated. I am using our desktop to post and I can not access the internet from the laptop. I did, when in adnavced menu, get it to boot once without the constant rebooting and it ended up at a blue screen saying I needed to run my anti-virus program. I am not that computer savy, so be prepared for a lot of questions.
