Reboot from SD card and Openhab on SSD disk

Hi I have a RP4 and moved 1jr ago my openhab instance to a SSD disk. So if i restarted my RP4 the system started based on the SD card, and the OH system / database is running on a SDD disk. Last week I tried to change my RP4 Case (a case with no fan). Due to a stupid action by myself i damaged the SD card. So I have a SSD disk with a full running openhab system and I need a new reboot SD card. My question is: how do I create I bootable SDcard without effecting my openhab installation on my SSD disk?
