【解决办法--实测可行】Partition 1 does not start on physical sector boundary.
新的硬盘使用fdisk进行划分的时候有提示Partition 1 does not start on physical sector boundary.
后面按网上找的办法，在fdisk进行分区的时候，输入u进行更改显示输入的单位，然后再删除分区，再进行添加新的分区就正常了。

By switching the "u" units. The default sector size will show up when you create the partition. If you are starting to partition a new disk and you get this error, you can.
1. create a partion with the defaut.
2. n,p,1,Enter, Enter
3. Display and get the partition error message. "p".
4. switch units "u"
5. delete the partition. "d"
6. Now create again. this time the defaults will show the correct sector. (in my case it was 1024).
以下是处理的实例：

至此，完结。
