I am using ubuntu 13.04. And want to have windows 8 pro on a separate partition of 150 GB along side ubuntu.
I did the same and installed windows 8 pro x64bit UEFI but when I try to repair grub to get ubuntu & windows 8 both in same page, ubuntu is able to boot from there but windows 8 is not. Windows 8 is just showing loading windows files and system reboot itself.
Please help, I tried multiple time re-installing windows 8 and grub but still no luck.
