Hi,

We bought several optiplex 3040 that came with windows 7 preloaded, all the machines include a purple cd with windows 10. I follow the instructions to reboot in UEFI mode, access the CD menu and selected to restore the PC, the machine starts working and after it shows that the restore is complete it reboots and shows the same menu all over again. What do I have to do in order to install windows 10 using this CD? what am I doing wrong?

Thank very much for your help

Kind regards!
