Windows 7 installation won't start

[Velnik]

I've been using windows 10 and wanted to go back to W7 and since I had a lot of problems since upgrading to 10 I decided to reinstall. I burned a DVD+ disc, made it bootable, changed the BIOS settings to boot from cd and made it through press any key to boot from cd. So after that i could select my region and language but that was it. After that it's just saying 'the installation process is starting' and I've been stuck all day at that. No progress. I tried yhe option repair my pc and right now all I got is the blue screen from windows 7 with my coursor on the screen. Someone please help because I'm dealing with a lot odlf issues with this computer and I'm getting sick and tired. I have toshiba satellite c855-2g7.

Probably a bad burn.

Download the iso again, wherever you got it from, and burn to DVD at no more then x4 speed. Use this simple program.

Have you had Windows 10 installed for more then 30 days ?

No I had it for 5 days or less. Is there something else causing this problem?

You should be able to do this: Windows 10 - Go Back to Previous Windows

I just did this on my Hp laptop that had Windows 10 on it for about two weeks. Having Nvidia video problems so rolled back to Windows 7 to fix it. Roll back worked fine.

Going from an older laptop with W7 to W10 is sketchy, you have to run the compatabilty checker first.

Did you do that ?

I checked it yeah. I upgraded to W10. And I can't roll back to W7 because I had the error delete all your accounts created while using W10 and the thing was I had 1 user account before the upgrade. Before that I had the black screen after boot and tons of other problems. After that my pc wont boot due to 'unmountable boot device' error.
