I just bought a new laptop (a lenovo ideapad Z500) and it came installed with Windows 8. I wanted to have Ubuntu on it too, therefore I resized the Win8 partition from the control panel and installed Ubuntu on the free space I created.
Ubuntu works perfectly, Windows does not load anymore...
I tried the recommended repair with Boot-Repair but it did not fix, now I get a "Windows boot loader failed to start" on startup and then I get the GRUB screen.
The partition summery created by Boot-Repair is here: http://paste.ubuntu.com/1444837/.
How can I fix this?
Thanks in advance for your help.

Edit: some more info after trying this for yet another. It looks like I'm not the only one having troubles with this, it seems that the whole Lenovo Z series is affected by this. I tried so far:

• I've followed this guide: https://help.ubuntu.com/community/UEFI
  I could not get the Live CD to boot. Tried the same with Live USB, no luck. The CD is not detected as a bootable device, the PC keeps rebooting with the live USB inserted.




• I've also tried this guide: http: //www.linuxbsdos.com/2012/11/05/dual-boot-windows-8-and-ubuntu-12-10-on-uefi-hardware/

No luck either, I get the Win 8 boot loader but I get an error message whenever I try to launch ubuntu UNLESS I accessed the BIOS and altered the boot order, in order to have Ubuntu on top of the list. This way I can access Ubuntu but not Win 8, unless alter the boot order again...

• Standard install from CD. After the installation completed I could not get Win 8 to boot anymore. Used boot-repair and I still had could not get Win 8 to boot.

Still looking for an acceptable solution, thanks for your help.
