MBR vs GPT - Secure Boot

[Wainuitech]

I haven't come across a tool that can convert a MBR drive to GPT without destroying the user data.

So from that POV no. it won't then load windows.

If anyone knows of one I would like to know...

You can convert the system from MBR to GPT. ( done it a couple of times) From Memory its a command you enter ( inbuilt in Windows) I'll look it up and post the details later tonight as soon as I find it.

EDITED:  FOUND IT    For once I wrote it down.  IMPORTANT -- Make sure you image the whole system 1st in case it fails.


4. Convert MBR to GPT:
If you're using an older MBR (Master Boot Record) partition style, you'll need to convert it to GPT (GUID Partition Table) to fully support UEFI and Secure Boot.
You can use the mbr2gpt tool (built into Windows) to convert the drive without data loss.
Important: Back up your data before using mbr2gpt or any other disk conversion tool.

Using MBR2GPT (Recommended):
1. Open Command Prompt as Administrator:
Search for "cmd" in the Start Menu, right-click on "Command Prompt," and select "Run as administrator."
2. Validate the conversion:
Type mbr2gpt /validate and press Enter. This will check if the disk can be converted without issues.
3. Convert the disk:
If validation is successful, type mbr2gpt /convert and press Enter. This will initiate the conversion process.
