My /boot is corrupted and unreadable

You need to be a lot more specific about the problems you are having. This is an interactive forum where we give you steps and you reply back with the results or questions to get the steps done.

I don't know of any download in the tutorial requires Facebook but please be specific so we can help you proceed.

If you already reinstalled and you still have the old WIn7 on the PC then you didn't follow the steps in Clean Reinstall - Factory OEM Windows 7 to delete partitions during install and create new one as you wish or just click Next to let the installer create and format your install partition for you.

I would do it over and this time follow the steps closely and if you have any questions ask back fully so we can help you and not just have to guess what you're trying to ask.

What has Fbook got to do with it? Can someone enlighten me ?

There's likely some obscure software (possible Paragon Rescue) which now requests registration via FB but it can be skipped. I don't have the time to go through every link in tutorial to find out which so maybe OP will enlighten us.

You're right - if you go to Paragon site - there is an FB link there.
