I needed to dual boot my computer with Windows 8 and another linux distribution (Fedora 18).
As instructed I turned off secure boot from BIOS and disabled UEFI before installation.
I created a separate partition and installed Linux on that.
I now have grub as my Primary boot loader. I see a windows 8 loader entry here, but I can't boot into Windows. As soon as I try to start it, the Windows boot loader returns an error.
Windows failed to start. A recent hardware or software change might be the cause. To fix this problem:
1. Insert your windows installation disk and restart your computer
2. Choose your language settings and click next
3. Click repair your computer
Since windows came pre-installed I do not have an install CD/USB. I created a boot usb using a friend's ISO. I've tried repairing my windows installation using the troubleshooting tools available on the Install/Recovery media.
The steps I tried included -
1. Fix/Detect Automatically.
2. Went into cmd and tried the following commands:
- bootrec /fixmbr
- bootrec /fixboot
- bootrec /rebuildbcd
- bootrec /scanos
They all return successfully, but I still get the same error on rebooting.
3. Running bcdedit returns an error.
I am sure that all my partitions are still intact, i.e the Windows OS partition and the Lenovo Recovery partition are both untouched.

Currently I can't boot up anything when I change the boot option from Legacy to UEFI in bios (Even the recovery media on the USB doesn't load)
I've been pulling my hair out and combing forums all over the internet but I don't seem to be getting anywhere. I don't have any data I'd like to save on either Operating system, but I would like to be able to get this setup up and running as soon as possible.
Any help will be sincerely appreciated.
