for days I have been crawling the web for solutions to my problem, but couln't find any. Here it is:
I got a new Laptop (ASUS Vivobook S200E) with Win 8 OEM preinstalled. I wanted to create a dual-boot system with Ubuntu 13 next to it. I read about UEFI and that I have to turn of Secure Boot and use the existing EFI partition as bootloader for Ubuntu. So I did. I also ran boot-repair reinstalling the GRUB. The result is when I start the computer I get into the boot menu. So far, so good. When I pick Win everthing is fine. But when I choose Ubuntu (recovery) the system starts, but gets stuck at the line '[1.806366] Switching to clocksource tsc'.
I already tried other versions of Ubuntu (12.04.2, 12.10). I played with boot-repair (using the recommended fix, setting everything manually). But nothing works. It's always the same issue.
I read that it could be a problem concerning graphic drivers, but this I can hardly believe.
If this is any help, boot-repair gave me this link to post in fora.
Thanks for any help in advance
I want to add that after a couple of frustrating days I decided to install Ubuntu as a single OS. Unforunately with no success, i.e. this problem has got nothing to do with dual-boot or Win 8 whatsoever. I hope that these new findings can bring some light into what the problem might be and how I can fix it.
I have tried editing the GRUB in order to set another clocksource as a kernel boot parameter (in recovcery mode - as the normal mode stays black resp. purple). Here is the list of settings I have tried:
No idea, what they mean or do, but these kernel boot changes had little or no effect at all. I found them on superuser.
