Converting MBR System disk to GPT

When using this option to convert my boot disk to GPT, the partition assistant will reboot the computer and try to apply the command, but I'm getting a KERNEL_SECURITY Error from windows 10, and the partition assistant stops with error 13.

Please help-

  • So is your computer bootable now? Any data loss?

  • Partition assistant was not able to perform any of the tasks on the partition, so yes, computer is bootable as before. Nothing was done to the partition.

  • Please try to convert the disk in Partition Assistant WinPE.

    Note: A backup of data is strongly recommended.

  • So you have a BIOS machine with a MBR boot disk and you want to convert the boot disk into GPT. Do you think this wil work? You need an UEFI machine in order to boot from GPT.

  • Machine is running win10 pro x 64bits. It can boot Legacy Bios and UEFI.
