Question: I dual booted ubuntu 12.04 LTS with Windows 8, but I wanted to get rid of ubuntu. So I got EasyBCD (on windows 8) and removed Ubuntu following a tutorial on youtube, then I got rid of the Ubuntu partitions. After restarting my Sony Vaio, it went to grub rescue and I'm not sure what to do. Help please! Much appreciated!!

I installed ubuntu using a USB.

Answer: 
You need to use a windows installation cd and restore the bootloader on the MBR through the recovery environment or using the startup repair option under advanced settings. Here is a guide <http://www.redmondpie.com/how-to-fix-windows-8-mbr-master-boot-record/>

Install again Ubuntu "alongside" of Windows 8, now entering Windows 8.

Install this software on Windows (is free): <http://download.cnet.com/MiniTool-Partition-Wizard-Home-Edition/3000-2094_4-10962200.html?part=dl-6285158&subj=dl&tag=button>

Run the software, right click in your disk and after in "Rebuild MBR", after click in "Apply" in top, now you can delete the partitions by Ubuntu **with that software, it's not necessary to run Ubuntu**, and after click in Apply.

Good luck!
