i had recently built my new pc with 4gb ram and an i3 3240 cpu and Asus p8h61 mx motherboard with windows 7. But when i converted my hard disk from MBR to GPT my computer is not booting and there is just a blinking underscore on top left corner. When my computer first came it was in GPT format. after which i wanted to re install the windows 7 but it asked for mbr format so i Converted it succesfully to mbr through easeus partition . after i installed the windows i wanted to convert it back to gpt which was succesful but a blinking underscore is coming. I will be thankful if there is a fix for that.
