![Grub 错误:ubuntu 和 windows 8 = 错误无效签名](https://linux22.com/image/1099725/Grub%20%E9%94%99%E8%AF%AF%EF%BC%9Aubuntu%20%E5%92%8C%20windows%208%20%3D%20%E9%94%99%E8%AF%AF%E6%97%A0%E6%95%88%E7%AD%BE%E5%90%8D.png)
我最近在装有 Windows 8 的分区上安装了 ubuntu 13,但我无法返回 Windows 加载器。当我选择 Windows 8 时,出现错误“签名无效”。但是 ubuntu 运行正常。
我已经在互联网上搜索并使用 os-proper 测试了解决方案,但没有任何改变:
