    Operating System Not Found after Kali Linux Installation

    I have a Sony Vaio E Series laptop that came with Windows 8 installed. I later updated to Windows 8.1. I have been trying to install a Linux distro as a dual boot option.

    Today, I shrunk the main partition on my C: drive to make room for a Linux installation (I made 16GB of free space). I burned Kali Linux 1.1.0a to a DVD, turned off SecureBoot and QuickStart in Windows and my UEFI settings, changed my default boot order to Optical Drive then Hard Disk. My Vaio wouldn't boot the DVD initially, so I put the boot setting to Legacy.

    I used the Kali Linux graphical interface for installation. I chose the free space made during the partition shrinking, and let it auto-install there.
    Installation went fine. I restarted my laptop and removed the Live DVD, but "Operating System not found" kept showing at startup. I put the Live DVD back in, and went through the steps at to try to make my computer recognize the partitions on my hard drive. Restarted, and still "Operating System not found".

    Running lsblk from the Live DVD gives the following:

        NAME        MAJ:MIN    RM     SIZE   RO  TYPE  MOUNTPOINT
        sda           8:0       0   931.5G    0  disk

        loop0         7:0       0      2.6G   1  loop /lib/live/mount/rootfs/filesystem.squashfs
    Best case scenario, I would love to get Kali Linux and Windows 8.1 working again. At the very least, I just want my Windows back. If you need any more information than I have provided, please tell me what you need. Thank you very much.

    Where's your boot partition? did you install grub (or lilo) during installation?

    Windows is still there so don't sweat that too much.

    Mine looks like this

    sda 8:0 0 232.9G 0 disk
    ├─sda1 8:1 0 100M 0 part
    ├─sda2 8:2 0 162.8G 0 part
    ├─sda3 8:3 0 1K 0 part
    ├─sda4 8:4 0 68.1G 0 part /
    └─sda5 8:5 0 1.9G 0 part [SWAP]
    sr0 11:0 1 1024M 0 rom

    sda1 is my first partition and is bootable, notice how small it is.

    Which is yours?
