Hi everyone - I've gotten myself into a bad spot and am not sure what needs to be done from here.
I cloned my fresh 8.1 install from my smaller SSD to my larger intel ssd with Acronis. The Intel drive is using GPT for the partition table, the Mushkin SSD was using MBR.
I tried following Attempt Three (at the bottom) on this guide to create a new boot partition but get stuck when trying to do bcdedit.exe with "Filepath could not be found" error.
Intel ssd currently has a 100mb FAT32 boot partition that I created NEW and the OS partition.

What do I need to do/type into the recovery cmd prompt to create a new boot partition/bootmanager/mbr to get my cloned OS install to boot?
edit: pretty sure my issue is that my bcdedit.exe is missing. How do i replace this?
