我已经在 Windows 7 Starter 上使用 wubi 安装了 Xubuntu。
我经常使用 Xubuntu，因此将默认启动设置为 Xubuntu 很有意义 :-)
这是当前列表：
PS C:\Windows\system32>.\bcdedit.exe /v

我尝试了这个：
PS C:\Windows\system32>.\bcdedit.exe /default {ddf99198-60c6-11e5-8ca7-hhhhhhhhhhhh}
输出：
The default entry is not valid as specified.
Run "bcdedit /?" for command line assistance.
The parameter is incorrect.
我也尝试了这个：
PS C:\Windows\system32>bcdedit /bootsequence {ddf99198-60c6-11e5-8ca7-hhhhhhhhhhhh} /addfirst
输出：
The entry list data is not valid as specified.
Run "bcdedit /?" for command line assistance.
The operation completed successfully.
接下来我尝试一下这个：
PS C:\Windows\system32>.\bcdedit.exe /displayorder {ddf99199-60c6-11e5-8ca7-hhhhhhhhhhhh} /addfirst
输出：
The entry list data is not valid as specified.
Run "bcdedit /?" for command line assistance.
The operation completed successfully.
它们都不起作用，还有其他指示吗？:-)？
答案1
这些 GUID 似乎都无效。首先，所有字符都必须是十六进制数字。其次，最后 12 位数字似乎不太可能都相同（如图所示），即使它们是有效的十六进制数字。
