Hello,
I tried creating recovery media using Dell Backup and Recovery application after upgrading to windows 10 and was not able to. I tried using my external HDD which gives an error during "Initializing Disk". And my USB Pen Drive is not even recognized by the application.
The application worked fine in Windows 8.1 previously. But after upgrade, the application was also updated to the latest version which is supposed to work fine with windows 10 and it is not.
