启动修复无法恢复,BIOS 无法识别 HDD

启动修复无法恢复,BIOS 无法识别 HDD

有人建议我在这里发布有关我的 Phoenix BIOS 在安装 Ubuntu 13.04 后无法从 HDD 识别(因此无法从 HDD 启动)的信息。

我已将启动修复工具的内容粘贴在下面,它似乎知道如何修复 HDD 的 MBR,但它仍然未在 BIOS 中显示并且无法加载操作系统。

我还意识到我甚至无法从 13.04 实时 CD 启动,这有关联吗?

任何帮助将不胜感激。

答案1

通过 BIOS 操作查找硬盘中嵌入的驱动器 Sr0。Sr0 是一个环回设备,如果我没记错的话,它会使用您的 DVD 或 CD 作为缓存设备。它可能会损坏硬盘,使其无法正确格式化

答案2

刷新 BIOS

在现代 PC 中,BIOS 存储在可重写内存中,允许替换或“重写”内容。这种内容重写有时称为刷新。这可以通过特殊程序完成,通常由系统制造商提供,或在 POST 时使用硬盘或 USB 闪存驱动器中的 BIOS 映像完成。包含此类内容的文件有时称为“BIOS 映像”。BIOS 可能会被刷新,以便升级到较新的版本以修复错误或提供改进的性能或支持较新的硬件,或者可能需要刷新操作来修复损坏的 BIOS。— Via维基百科

如果我理解正确的话,你应该能够访问你的计算机 manfac 网站并将 BIOS 更新保存到跳转驱动器并刷新 BIOS,除非所讨论的系统足够旧以具有 EEPROM(从你的描述来看令人怀疑,我很高兴 dip 开关也消失了)

尽管您可以尝试运行 freedos,安装fdisk并查看当您尝试编写新操作系统时分区是否出现问题,fdisk但当窗口在分区拆分期间停滞时,freedos 允许我重写我的分区,让我的 BIOS 识别并安装 Ubuntu,从而保存我的系统!
