Ubuntu / Debian的预置工作正确 – 系统可启动.
但fdisk -l正在产生以下结果：
Disk /dev/sda: 50 GiB,53687091200 bytes,104857600 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: dos Disk identifier: 0x000e157a Device Boot Start End Sectors Size Id Type /dev/sda1 63 192779 192717 94.1M 83 Linux /dev/sda2 * 192780 1172744 979965 478.5M 83 Linux /dev/sda3 1172745 96470324 95297580 45.5G 83 Linux /dev/sda4 96470325 104856254 8385930 4G 82 Linux swap / Solaris Partition 1 does not start on physical sector boundary.

我在preseed中的当前分区参数是：

如何避免分区{n}无法启动物理扇区边界错误.在预播期间如何在partman中设置正确的起始扇区和扇区大小？
将您的d-i partman / alignment参数更改为最佳而不是圆柱.这应该可以解决问题.
