Hiya! Absolute Linux newbie here...

We have a new Lenovo Yoga laptop with split HD running Windows and Linux OS. One of the first times it was in use we used Skype on Windows until it ran out of batteries. When I try to start it now I get this message:
------
GNU GRUB versjon 2.02 beta3-4ubuntu2

Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions.

grub>
------
I tried googling + searching this fora without luck...anyone who feel called upon to (patiently!) walk me through this? ...Even better, anyone in Drammen, Norway who wants to help the Green Party and come and do this?
Cheers, Max

You could start by posting which version of windows and which version of Linux you are using.
Also, UEFI/GPT or the older MBR.
I don't really see how running Skype on windows could subsequently prevent booting.

Thanks for answering...but I've actually submitted all the info I'm aware of. I supposed the "2.02 beta3-4ubuntu2" would tell which Linux version it is, as for Windows; no idea, but brand new laptop so newest version I suppose (I haven't used Windows for 15 years and don't follow their development).

UEFI/GPT or the older MBR....? You might as well write WTF? Means nothing to me...But I'll go ahead and ask the guy who installed it.
As for Skype: I don't think thats the culprit, just wanting to inform about exactly what I did. As far as I could learn from googling, there's some upstarts file which "Grub" can't locate, and I have to locate them for it... ? Don't know if it's true...and don't know how.

Windows 10, Ubuntu Gnome 17.04, UEFI Lenova Yoga 510/14ISK, Model 80S7 ...Any help?

It's been a long while since I used grub, but might this be a prompt to select the OS to boot?
What happens when you type TAB?

Auch: If you're really interested you might manage to read it from either of these 2 images...or simply recognize the wide selection of potential commands: It's just too much to sit and type and I can't access any screengrab options on the Lenovo computer...

Possibly Win10 hibernation getting in the way.
Get into the power-on boot list during the black screen after power-on - maybe F12. Select Windows from there and close it down properly. Then reboot and see if grub works then. Else we'll have to give you some recovery instructions.

Did the person who installed Ubuntu give you the installation DVD or flash drive? If you have that, there are a number of ways to attempt to get more information to try to ascertain what the problem might be such as using the boot repair software.
