There is no Startmenu tab on any of my machines either. I run W10 pro - Dutch language...
Hello, probably the problem lies in the recovery system that has been delivered with the laptop. These tools are not designed to upgrade a sysem. So the remedy i would try is: Use a program to boot the system and clean all partitions on your hard disk (Paragon HD suite in the free version would do) Than have a clean W7 install on the hard disk. Upgrade to W10. Succes!
