  1. Create a system repair disc (http:\/\/windows.microsoft.com\/en-US\/windows7\/Create-a-system-repair-disc\u00a0\"Jump\"\u00a0<\/a>). You can skip this step if you have a Windows installation media. Is a good measure to reboot and verify you can start your system from this disc.<\/li>
  2. Identify which disk you want to convert (usually is #0). This can be done by looking at the number in the Windows Disk Management.<\/li>
  3. Download gptgen from here\u00a0http:\/\/sourceforge.net\/projects\/gptgen\u00a0\"Jump\"\u00a0<\/a>. (You could use the Windows Disk Management Tool for this too. (diskmgmt.msc)) This tool will allow you to convert your MBR disc to GPT with the data included.\u00a0<\/li>
  4. ATTENTION: After this step, your computer CANNOT BOOT until the whole process is completed. DO NOT Shut Down Unless Instructed to!\u00a0<\/strong>

    Unzip gptgen and then run CMD with elevated\u00a0privileges. (replace the 0 with the identified disk number).<\/p>

    This *will* result in a BSOD\u00a0shortly after and it’s to be expected:<\/p><\/code>

    gptgen.exe -w\u00a0<\/em><\/strong>\\\\.\\physicaldrive0<\/em><\/strong><\/a><\/code><\/p><\/li>

  5. Boot using your Windows installation or previously generated system repair disc.<\/li>
  6. Choose language and preferences, and then select\u00a0Repair Your Computer<\/em>\u00a0->\u00a0Troubleshoot<\/em>\u00a0->\u00a0Advanced options<\/em>\u00a0->\u00a0Command Prompt<\/em><\/li>
  7. We will need the disk partitioning tool. With this, we will recreate the boot partitions. Type:<\/code>

    diskpart<\/em><\/strong><\/code><\/p><\/li>

  8. Identify the boot disk where Windows is located, typing:

    list disk<\/em><\/strong><\/code>\u00a0<\/em><\/p>

    \u00a0Something like this should appear:<\/p>

     <\/p><\/code>

    \u00a0\u00a0\u00a0\u00a0\u00a0 Disk ###\u00a0 Status\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Size\u00a0\u00a0\u00a0\u00a0 Free\u00a0\u00a0\u00a0\u00a0 Dyn\u00a0 Gpt<\/strong><\/code><\/p><\/code>

  9. Once identified, select the disk (replace with the correct number):<\/code>

    select disk 0<\/em><\/strong><\/code><\/p><\/li>

  10. Verify the partitions:

    list partition<\/em><\/strong><\/code><\/p><\/li>

  11. Something\u00a0similar at\u00a0the info below should appear.

    \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0Partition ###\u00a0 Type\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Size\u00a0\u00a0\u00a0\u00a0 Offset<\/em><\/strong><\/code><\/p>

  12. Delete the previous system partition:

    \u00a0\u00a0select partition 1<\/em><\/strong><\/code><\/p>

    \u00a0 delete partition<\/em><\/strong><\/code><\/p><\/code><\/li>

  13. Create the new boot partition, Microsoft reserved partition:

    \u00a0\u00a0create partition EFI size=100 offset=1<\/em><\/strong><\/code><\/p>

    \u00a0\u00a0format quick fs=fat32 label=\"System\"<\/em><\/strong><\/code><\/p>

    \u00a0\u00a0assign letter=S<\/em><\/strong><\/code><\/p>

    \u00a0\u00a0create partition msr size=128 offset=103424<\/em><\/strong><\/code><\/p><\/li>

  14. If you list the partitions again, you should have ended up with something like this:

    \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Partition ###\u00a0 Type\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Size\u00a0\u00a0\u00a0\u00a0 Offset<\/em><\/strong><\/code><\/p>

  15. Ensure that your Windows installation is mounted, replacing 3 with the volume number of the Windows installation (usually 1):

    \u00a0\u00a0list volume<\/em><\/strong><\/code><\/p>

    \u00a0 select volume 3<\/em><\/strong><\/code><\/p>

    \u00a0 assign letter=C<\/em><\/strong><\/code><\/p><\/li>

  16. Exit diskpart:

    \u00a0\u00a0exit<\/em><\/strong><\/code><\/p><\/li>

  17. Generate boot partition data, replacing C: with the letter of the Windows installation (usually C:):

    \u00a0\u00a0bcdboot c:\\windows \/s s: \/f UEFI<\/em><\/strong><\/code><\/p><\/li>

  18. Cross your fingers and then\u00a0restart your computer!<\/strong><\/code><\/li><\/ol>
