Hi Greg. Thank you for being willing to help. I read the post www.grooovypost.com/howto/dual-boot...
I've been at this off and on for several days now. I've spent time at askubuntu.com. I've been on the lenovo forums. Let's not forget every possible suggestion from the internet.
So, the post is straight forward, the instructions clear. I've followed them many times.
Some background. The first time I downloaded an ISO of Mint I ended up overwriting my windows OS. So, I restored Windows, all went smoothly except for a missing DLL for powercfg which I managed to find and restore. The above process gave me a ubuntu selection
on the boot menu.
Subsequent installs of either Mint or Kubuntu appear to be successful. I can live boot the OS from the USB and see it's installed. My problem seems to be with the boot loader. I would prefer to have the Microsoft Windows graphical boot manager rather than
the boot setup that comes as part of the UEFI from Lenovo. GRUB doesn't install as the groovypost indicates.
Hope I'm being clear about this.
