0x000000e blue screen error on boot after mbr2gpt
Hello,
I just tried converting my boot disk to gpt in order to upgrade to Windows 11 from 10. I don't have screenshots on the cmd while doing so, but I remember it said it was successful. I have disabled CSM support and enabled Secure boot and made sure it says secure boot is active on the BIOS as well, but I still get this error when trying to boot. I do have 2 identical boot options which I've read can happen after mbr2gpt, but neither seem to work.
I am able to boot in safe mode and would love any help getting my PC to boot now, and while I'm fine with wiping and rebuilding windows as a last resort, I would love to not have to reinstall everything. I take being able to boot in safe mode as a sign I might just have to repair with my partitions or something so I'm hoping I don't have to reset everything.
Thank you!

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.
Converting your disk from MBR to GPT and configuring BIOS/UEFI settings can sometimes be tricky, especially when boot options appear duplicated or fail to boot properly afterward.
Given that you can boot in safe mode, it's a good sign that the system is not entirely failing.
You can do this by interrupting the normal boot process 3 times, causing Windows to enter Automatic Repair.
Alternatively, use a Windows installation USB or DVD to boot into recovery mode.
Windows 10's "Settings > Apps > Startup" list is designed to control which apps automatically launch when you log in, but it only includes apps registered with the system's startup entries—mainly those registered via the app's own settings or the Task Manager. It does not support adding arbitrary applications like fan control software directly to this list in a way that differentiates between launching in the Game Bar environment or the desktop environment.
If still unsuccessful, consider clean installing Windows 11 after backing up your data, as sometimes conversions and BIOS settings can cause persistent issues.
