Can I convert my mbr ssd to gpt?

I tried cloning my hdd to my ssd and screwed by setting the ssd to mbr instead of gpt using AOIMEI so can i use the same program to convert it to gpt without needing another boot drive. I tried formatting it in windows, but that wont allow me to do it since the ssd is the boot drive unless I have another boot drive

while this is theoretically possible, I'd surely want to back up everything ["mirror"] the entire drive before I did it.  Frankly, I'm not familiar with that program and do not know if doing this would inherently format [wipe] the SSD.  You'll need a mirror program that runs from DVD or USB [and includes own mini operating system]
