在尝试(并失败)在11.10中安装更好的ATI驱动程序后,我以某种方式在启动时丢失了grub菜单。屏幕的确变为熟悉的紫色,但是它不是启动选项列表,而是空白纯色,然后迅速消失并正常启动到默认条目。
我如何找回引导程序?我已经尝试过sudo update-grub
并且在分辨率和色彩深度的各种不同组合中都startupmanager
没有成功(640x480、1024x768、1600x1200、16位,8位,10秒延迟,7秒延迟,2秒延迟...)
编辑:
我已经尝试在启动过程中按住Shift键,但它似乎并没有改变其行为。我在终端中收到消息“ GRUB Loading”,但是随后正常出现grub菜单的地方出现了一阵空白的洋红色屏幕。
