The Windows 10 tablet RCA Cambio w101 has a built-in internal flash drive of only 32GB as disk 0. This does not suffice because my Windows installation already uses 29GB. Right now I can boot from the efi partition of disk 0 only into the Windows partition C: on disk 0.
My goal is to preserve the efi partition on disk 0 but to have Windows on an external drive as disk 1 and then hide the Windows partition C: on disk 0. As a first step in this direction, I attempted to create a dual boot in the boot manager.
So far I cloned the Windows partition to an SD card and added this partition's drive letter to the BCD using EasyBCD. When I choose the SD card in the boot menu, it does not boot. I tried the same with a USB stick, but the problem persists.
Experimenting with alternatively the stick and the SD I messed up the BCD. Right now it looks like this:

I know how to add and delete entries in EasyBCD. But how can I delete and edit lines? I mean just to edit, not using the complicated commands of BCDedit?
