I have been trying to install windows 10 pro, 64 bit using my usb pen drive. I have completed the necessary procedures to make the usb bootable. The problem i am facing is that everytime i try to install the windows in the hard disk an error message pops up saying, 'windows cannot be install, the selected disk is of GPT partition style'. So after that i used rufus to convert the usb to gpt partition style for UEFI boot and also using the iso of windows 10. But i can't boot the pendrive now. The iso file was around 7gb so i had to use the ntfs system. What should i do now rather than converting the hard disk to MBR partition style?
