Feedback for mbr cmd convert script

I ran into an issue validating and converting a drive to mbr - when running the command prompt script found on the following ea help page: https://help.ea.com/en/articles/technical-issues/secure-boot/

The suggested command is:

mbr2gpt /validate /disk:0 /allowfullOS
mbr2gpt /convert /disk:0 /allowfullOS

It would run into an issue saying it was an invalid argument.

I had to change the lowercase "f" to a capital "F" in order for the command to be valid and then allowed me to convert the disk to gpt and follow the remaining instructions listed on the webpage (did not think about taking a screenshot at the time).

mbr2gpt /validate /disk:0 /allowFullOS
mbr2gpt /convert /disk:0 /allowFullOS

When I ran an additional test on a system where the boot drive was disk 2 - it did not like me entering disk:2 but allowed me to use a lowercase "f".

I do not know the rhyme or reason about the second test - but thought on the EA website, the string listed should be corrected for the "F" to be capital, so when users copy and paste - it will match the screenshots on the website and allow them to convert without running into an invalid argument error.
