Hi, the weekly testing ISOs for i386 and amd64 are now equipped with the new MBR:
https://cdimage.debian.org/mirror/cdimage/weekly-builds/i386/iso-cd/debian-testing-i386-netinst.iso https://cdimage.debian.org/mirror/cdimage/weekly-builds/amd64/iso-cd/debian-testing-amd64-netinst.iso Testers wanted for booting this ISO from USB stick. One can recognize the new MBR by the MD5 of bytes 32 to 431: $ dd if=debian-testing-i386-netinst.iso bs=1 skip=32 count=400 2>/dev/null | md5sum 1705df1b3dee9b725432e099ecc63eaf - $ dd if=isohdpfx.bin.170324 bs=1 skip=32 count=400 2>/dev/null | md5sum 1705df1b3dee9b725432e099ecc63eaf - The old MBR, which caused this bug report, yields 2b1369901086845791f595a9aa8b1a16 Have a nice day :) Thomas
