错误:未检测到启动盘或磁盘发生故障

我有一台 acer-pc,一开始安装了 oem windows 8 或 8.1 x64。后来我想安装自定义 ubuntu。我检查了 oem/normal/x86/x64 和其他 windows 安装。我甚至在其他硬盘上安装了操作系统,我以为可能是光盘问题,但事实并非如此。

现在,在 x64 ubuntu 安装之后,它仍然显示ERROR: No boot disk has been detected or the disk has failed.不允许以任何方式使用该电脑的消息。

我已经从 usb 启动了 ubuntu(在 oemubuntu/next/next 安装之后)它显示:
