After rebooting, the same image worked fine. The installer also works fine and looks great! Also, I used the non-iso9660 disk image because the iso9660 disk image (not documented on the page above either) has 1.5 MB (not a typo). $ file /gnu/store/lcx2w0y6pi6av4qhipmwc9xjzy4p7gbd-image.iso /gnu/store/lcx2w0y6pi6av4qhipmwc9xjzy4p7gbd-image.iso: DOS/MBR boot sector; GRand Unified Bootloader, stage1 version 0x79, boot drive 0xbb, stage2 address 0x8e70, 1st sector stage2 0xb8db31c3, stage2 segment 0x201; partition 1 : ID=0xee, start-CHS (0x0,0,2), end-CHS (0x3f8,9,12), startsector 1, 3121451 sectors, extended partition table (last) $ stat /gnu/store/lcx2w0y6pi6av4qhipmwc9xjzy4p7gbd-image.iso File: /gnu/store/lcx2w0y6pi6av4qhipmwc9xjzy4p7gbd-image.iso Size: 1495040 Blocks: 2920 IO Block: 4096 regular file Device: 801h/2049d Inode: 34661153 Links: 2 Access: (0444/-r--r--r--) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2019-03-27 23:25:26.240200749 +0100 Modify: 1970-01-01 01:00:01.000000000 +0100 Change: 2019-03-27 23:25:26.248200669 +0100 Birth: -
