In my case the command worked and I was able to successfully create my recovery drive:
reagentc /setreimage /path \?\GLOBALROOT\device\harddisk0\partition2\Recovery\WindowsRE
for others that are confused, you need to select the primary drive that the os is on (the one your laptop is booting from). as for the partition, you need to select the one that says system using its number (the order it is in from left to right)
