Solved! Laptop gets blue screens after format

[taki tsan]

I formatted my Lenovo b5400 from Windows 10 to Windows 7 64bit ultimate and for some reason I get constant blue screens (didn't get any before) and I can't install Windows updates. I run chkdsk /f/r and sfc /scannow and the windows memory diagnostic tool.

You may have to get the OS on a CD/DVD/USB and try reinstalling it from there.
