Hi,
The 0x000000e error after running mbr2gpt usually indicates that the boot configuration (BCD) or the EFI partition wasn’t created or updated correctly.
This can happen if the disk didn’t meet all the mbr2gpt requirements or if the firmware wasn’t switched to UEFI mode after the conversion.
To help further, it would be useful to know:
- the exact mbr2gpt command you used,
- whether the tool returned any warnings or errors,
- and whether the system firmware was switched from Legacy/CSM to UEFI after the conversion.
If you can share a screenshot of the error and the output of mbr2gpt, we can narrow down the root cause.
