在遇到 NVIDIA、wifi 和登录循环等问题后，我从 Linux Mint 迁移到了 Ubuntu，但通过按照此站点说明保存我的主文件夹，我找到了一些我曾问过的问题这里和这里：
迁移到 Ubuntu 18.04 后出现 NVIDIA 驱动问题
安装 Ubuntu 18.04 时出现问题（双启动和单独的主文件夹、NVIDIA 显卡杂项），但从 USB 运行 Ubuntu 可以正常工作
在这种情况下，Ubuntu 陷入了登录循环，之后我必须按下ctr+alt+f3并运行sudo startX，将 NVIDIA 设置为xconf...选项并执行sudo apt purge nvidia*（在伪 startx` 之前）。才能访问低分辨率屏幕，并且没有正确安装英特尔驱动程序，这很烦人。有关更多信息，您可以查看我之前的问题。
我尝试从实时 USB 安装 Ubuntu，并尝试格式化/dev/sda3和分别/dev/sda7将它们设置为/home/和，/但在安装过程中出现一些错误，从实时 USB 重新启动时卡在安装过程中，现在它第一次无法显示我的硬盘驱动器，运行后sudo fdisk -l它显示我的硬盘分区，但/dev/sda7您在此处看到的除外：
因此输出sudo fdisk -l是：
ubuntu@ubuntu:~$ sudo fdisk -l

那么你建议根据这个做什么邮政：
很多地方都问过这个问题。您需要将 BIOS 中的 SSD 控制器设置从 RAID 更改为 AHCI，否则 Linux 将找不到它。
但缺点是您需要在 AHCI 模式下修复或重新安装 Windows。
为什么使用命令后其中一个分区没有显示fdisk？此外，执行此操作后我的双启动是否被删除？如果是，如何恢复它以便像迁移之前一样使用新的 Ubuntu 操作系统访问 win 和 Ubuntu？
感谢您的关注。
