I bought Asus Notebook with preinstalled Windows 8 x64. I am using Norton Ghost from Hiren 's Boot CD to make image a hard drive, but something I'm broke and my Windows will not start, search the installation disk to perform the repair., But when you do the work, again asking for the same repair. Doubt that I Corrupt MBR or GPT. I do not know which system is followed in my HDD. How to find out whether the MBR or GPT and how to try to fix it? Thank you in advance for your help.
