我之前在系统上运行的是 Windows 7，但由于 Windows 7 中出现“未找到可启动设备错误”，我决定重新安装 Ubuntu。我使用 HP 恢复实用程序对硬盘、处理器等进行了所有测试和检查 - 所有组件都通过了所有检查。因此显然没有硬件问题。
接下来，我从实时 USB 启动 Ubuntu，由于我可以使用 Ubuntu 访问驱动器，所以我备份了我的数据并使用 GParted 删除了所有现有分区。
现在，它看起来像这样： 分区
我有 2 个硬盘 - sda（见截图 - 500 GB）和 sdb（28GB，采用英特尔快速启动技术 - 我打算保留这个硬盘原样）
sda1 - Windows 7 的启动分区。我没有改变这个
sda2 - 我删除了所有现有分区并合并到此分区。我想在此分区上安装 Ubuntu。
现在，当我运行 Ubuntu 安装程序时，它检测不到 sda。安装程序仅显示 sdc（USB 闪存驱动器）
其他信息：我的 BIOS 中没有任何 RAID 选项。我的系统在传统模式下运行。
sudo fdisk -l 检测驱动器：

这里出了什么问题？
答案1
从 Live USB 运行 Ubuntu 安装程序。转到安装程序菜单底部，选择“执行其他操作”。您应该从那里看到 sda2。请注意，在 Gparted 输出图像中，您显示正在使用 8+GB。您可以覆盖它，也可以返回并使用 GParted 将这些数据放入其自己的分区中，然后在空分区中安装 Ubuntu。
