So i formatted my hard drive (NTFS) from ubuntu cause its just not the operating system for me and it just froze so i had no choice but to press the power button. I thought it worked because the operating system will no longer boot, it says "grub error unknown file system" so i went to install windows 8.and i went through the windows 8 instilation and when i need to select my drive it says "windows cannot be installed to this hard disk space. the partition is of an unrecognised type. I dont know if i fucked up my hard drive or what. I just want to install windows 8 and its a laptop so i dont think i can plug in the hard drive to my desktop and format it that way.
