I\'m having this weird error and I did not suceed to find the origin. First of all I would like to say that I succeeded to perform some installation of Magento 2 on a window
An easier would be to run below command from magento root folder.
php bin/magento setup:static-content:deploy
This will feed the content perfectly in respective folders. If you have specific language then run like below.
php bin/magento setup:static-content:deploy en_US
php bin/magento setup:static-content:deploy en_GB
