I tried different combinations and every change that resulted in Fedora installer seeing the drive, broke Windows 10 boot setup. I thought I would be able to enable UEFI after the setup and use Windows 10 whenever I needed it and decided to install Fedora.

Programming, , , ,

The default Twitter Follow code, the script loads the like button synchronously. When you add the synchronous Twitter Follow button to your website, Page Speed Online will tell you to prefer asynchronous resources.
