Ubuntu 无法调整分区 /boot 的大小

我无法调整分区启动的大小，我看了很多教程，但都不起作用。我不知道为什么。我想调整 sda5 的大小并从中取出 1gb，然后将 1gb 给 /Boot

在此处输入图片描述

我在终端中输入了 sudo fdisk -l：

Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders, total 312581808 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

我认为您无法调整当前正在使用的分区的大小。您可能需要从 USB 启动或双启动才能调整分区大小。
