Hello
I'm facing a strange problem. I had my laptop dual booted with Windows 7 and Mint 17.1
Till last week all was okay.
Yesterday when I tried to boot into Windows via grub, grub froze at the keystroke. Since I couldn't boot into Windows, I made Windows as default in grub.cfg.
I'm facing the same issue now trying to boot into mint. I defaulted the MBR to Windows using Windows recovery but when I tried to boot into mint using a live CD, mint is still not booting.

I tried the following:
1. Boot via Bootrepair liveCd but the same issue: it did not boot
2. Removed HDD and tried booting but prompt keeps looping back to BIOS


Can someone suggest what could be the issue? I am running a surface test on HDD to check for any issues..
Although I am not very sure but could it be related to BIOS or corrupt partition table? Can you point me to some good tool for creating new partition table?

From the live environment, what is the output of:

What's a boot-repair liveCD? I downloaded boot-repair during a LiveUSB Ubuntu session and ran it from there.

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair
https://help.ubuntu.com/community/Boot-Repair

I can run these commands but the live environment does not boot... The live USB does not boot.. the only thing booting is Windows ..
Is there any tool which I can use to delete the existing partition table and create a new one..

I have tried resetting the boot and mbr using bootrec.exe but no improvement
