Trying to convret from MBR to GPT, found out my boot is in one drive and system in another

Not entirely sure how this happened, I built this computer about a year ago now, and I wanted to upgrade to windows 11 but I cannot get UEFI boot options since my boot drive is set to MBR. I also cannot convert it because, based on what I found, I have my boot on one SSD and my system on another. I am not sure how that happened since when I installed windows on the newly built PC I only had my boot drive physically plugged into the MOBO. I am attaching what my drive manager looks like and the MBR to GPT conversion failure.

Hello @ChristopherDavila-1285,

Thank you for your question.

I believe you need to convert the unit recognized as MBR to GPT, because not all computers recognize MBR as acceptable.

To convert from MBR to GPT just consult the article below and check the step by step:

https://docs.microsoft.com/en-us/windows-server/storage/disk-management/change-an-mbr-disk-into-a-gpt-disk

Also, I recommend that you post the windows 11 question on the windows insider forum, there you will have all the guidance on how to install the new Microsoft system correctly.

To do this, just click on the link below and select the top option called "Ask a question" and describe all your doubts:

If the answer was helpful, please don't forget to vote positively or accept as an answer, thank you.
