Had to download SystemRescue ISO after failed system update, where all partition information from SSD was gone. Before generating new bootloader on system update with “zypper dup” got warning messages “device /dev/sda is missing” and after hard reboot SSD detected by BIOS, but “no bootable disk” displayed. With “testdisk” found 3 partitions, write them and system started fine from last working state. So, why not add testdisk utility to Tumbleweed ISO too?
