That is exactly what the netinst image provides: root@hawk:/crc/isos/debian# fdisk -l 13.x/debian-13.0.0-amd64-netinst.iso Disk 13.x/debian-13.0.0-amd64-netinst.iso: 754 MiB, 790626304 bytes, 1544192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x4f2c5af7 Device Boot Start End Sectors Size Id Type 13.x/debian-13.0.0-amd64-netinst.iso1 * 0 1544191 1544192 754M 0 Empty 13.x/debian-13.0.0-amd64-netinst.iso2 4108 11307 7200 3.5M ef EFI (FAT-12/16/32) root@hawk:/crc/isos/debian# Have you checked for firmware updates for the motherboard? -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
