Default partitioning scheme


  • This may be a silly question and may have been answered previously, but is GPT the default partitioning scheme for Windows 8?  I only ask because when I installed Developers Preview and viewed the physical disk at the byte level, it appears to be GPT - the first physical sector is the MBR and then at PS 2048, there's a backup MBR and at PS 2049, it looks like it's GPT, but the signature EFI is not present.  Any help will be greatly appreciated.  Thanks!

  • It would've been great! I'll add that it doesn't seem to be possible to boot from a GPT when installing to a VHD. I mean that you can't create a GPT partition on the VHD.

    Well this is the world we live in And these are the hands we're given...

  • Thanks for the response!  I installed Windows 8 on a wiped basic disk on a different computer, so it is the only OS running - I'm not using a VM.  So, I'm still wondering if Windows 8 defaults to GPT on the install.  Thanks again!

  • All of my Win 8 installs (both physical and virtual) have been standard MBR.

  • Thanks for responding - I really appreciate the input.  GPT also has an MBR so that legacy software, like disk utilities, will still function, so I am also seeing an MBR.  I'm not doubting you, I'm really just trying to figure out which is the default partitioning scheme - MBR or GPT?
