As far as I know, no one has discovered a short way of doing this. This means that you will need to use the long way:
(1) Copy all of your personal files from the SSD to an external USB disk.
(2) Change the partition table of the SSD from MBR to GPT.
Note: this destroys ALL partitions on the disk.
(3) Re-install Windows in UEFI mode.
(4) Copy your personal files from the USB disk to the SSD.
(5) Update the BIOS.
The alternative is to choose NOT to update the BIOS. Do you need to update the BIOS?
