Update your UEFI BIOS to revision A13 then reattempt: [URL]
Hello All, Hello Support, Dell Backup and Recovery software suggested to me that I upgrade to Windows 10. I like that idea. I checked my ultrabook on DELL website. Inspiron 7537 is Tested (Dell proudly says) so I should be able to upgrade my OS flawlessly. I made 2 attempts to upgrade to Windows 10, both failed in the same way. It goes through several stages but at a certain point a black screen stuck and only power button OFF makes the laptop do something (turn off). In both attempts after 2 restarts, the installation process reverted my operating system to Windows 8.1 Why DELL say it is tested and I can upgrade - it proves otherwise - does not work. I would not be contacting DELL forums about this (because DELL support in my country told me this is Microsoft business)  IF IT WAS NOT FOR THE FACT that DELL 'advertise' me Windows 10 and claims my laptop is ready to do the upgrade. Please assist and explain. Thank you all in advance. Martin
