Step 7 Fix:


==========


 


The directory '/home/stack/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Changed ownership of /home/stack/.pip from root:root to stack:stack

Windows 10 & Fedora 25














Windows 10 (pre-installed)



1> Got a blank screen ... decided to bypass configuration of feature like cortana

      to get the real screen.

2>  





Fedora 25 on new Dell Notebook Insprion 14 7000 series.



1> No CD/DVD drive.



2> Downloaded fedora 25 workstation .iso image from fedora site after comparing both Fedora and Ubuntu for a while.



Decided to go with Fedora as in company I have to rely on OEL. 



3> Too many recovery partitions on the pre-installed notebok. Finally, got 400 GB unallocated. 



4> Tried different tools to burn .iso image to bootable usb stick.



      fedora media writer : didn't detect the usb stick.

      lili (live linux) : image didn't boot (supported only till fedora 22 workstation)

      rufus : did the trick for me



5> F12 gives boot options: boot from usb or windows 10 from EFI boot partition


6>  Scanner : Got it working through 'simple scan' (yum install sane-*)



7>
