I would like to dualboot Xubuntu 13.10 and Windows 8 from the GRUB2 menu without reinstalling Windows 8; I don't have any Windows reinstall media besides the Recovery partition on the internal HDD.
I'm not new to Linux or Ubuntu or dualbooting, but the UEFI stuff confounded me; so, I picked my way through the initial installation of Xubuntu 13.10 on an Asus laptop with Windows 8 64-bit pre-installed. Nevertheless, I ran into a problem immediately in that the Installer never detected the Windows installation. I chose the 'Something Else' option and manually configured some partitions behind the Windows, keeping the Linux boot partition separate from Windows's, and I may have assigned a 'boot' flag to Linux's boot partition.
On reboot, Windows 8 booted immediately with no sign of Linux. However, after fiddling with the System Setup and manually pointing to Linux's .efi files, Xubuntu booted. But now, no Windows boot.
Currently, all the Windows boot features were disabled (FastBoot, hibernation), the single hard drive is UEFI set, SecureBoot-enabled, boot manager is GRUB2 with functioning Linux entries and non-functioning Windows entries. Boot-Repair was installed and run from the HDD-installed Xubuntu system; I only used it to generate a BootInfo Summary here: http://paste.ubuntu.com/8273250/
Some things stand out: sda5 reports two different starting points, a warning about the Linux boot partition being too far from the disk's start...
But where do I go from here?
