我在 Toshiba Satellite Chromebook 上安装新操作系统时遇到问题。我继续遇到一条消息“您插入的设备不包含 Chrome OS”。
我基本上遵循了 Chrome OS 的探索你的 Chrome OS 设备。我启用开发者模式后，设备自行清除。我可以通过++ESC进入开发者模式，并收到消息F3Power“启动验证已关闭”然后我收到一条消息“Chrome OS 缺失或损坏”。我对此没意见，因为我正在安装一个新的操作系统。
然而，当我插入 U 盘时debian-8.3.0-amd64-lxde.iso dd'd 到它，它会产生消息“您插入的设备不包含 Chrome OS”。插入 U 盘启动时，我收到同样的消息。尝试启动时，我也收到同样的消息debian-8.3.0-i386-lxde.iso。
根据产品论坛和Chromebook Central 帮助论坛，可能是 U 盘制造商或物理 USB 端口的问题。论坛问题指出 ScanDisk 驱动器存在问题，但我尝试了两者必恩威和通用制造商称为USB2.0（根据dmesg）。论坛帖子还指出 USB 2.0 和 3.0 端口可能存在问题。我尝试了两个 USB 端口，但都没有成功。
我还发现一条消息说使用CTRL+ U（USB 启动）启动，另一条消息说使用CTRL+ L（传统启动）启动，但都没有帮助。
你知道实际启动另一个操作系统的秘诀是什么吗？
以下是输出crossystem --all。我相信它是通过 USB 启动进行的；而不是通过 Legacy 启动。
