在Windows 10之后安装Ubuntu时出现多个错误

（请阅读评论以便更好地理解）

所以让我从头开始。

我在Windows 10中下载了Ubuntu并将其刻录到USB。当我重新启动时，我看到了启动选项并被选中Install Linux。我到了需要格式化所有数据的步骤。因为很晚才关闭电脑。

当我下次打开电脑时它正在显示

Boot device not found

经过多次尝试，我知道我必须安装Linux，所以我开始了。我选择“擦除磁盘”并出现以下错误：

所以，我选择了“其他东西”，我得到了这些分区：

我还通过磁盘工具格式化磁盘，现在它们如下：

/dev/sdb contains GPT signatures, indicating that it has a GPT table.  However, it does not have a valid fake msdos partition table, as it should.  Perhaps it was corrupted -- possibly by a program that doesn't understand GPT partition tables.  Or perhaps you deleted the GPT table, and are now using an msdos partition table.  Is this a GPT partition table?

命令sudo gdisk -l /dev/sda给出了以下结果：

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!

Do you want to proceed? (Y/N): y
OK; writing new GUID partition table (GPT) to /dev/sda.
yWarning: The kernel is still using the old partition table.
The new table will be used at the next reboot.
The operation has completed successfully.

我通过@TomYan给出的命令很少发现

我用了 sudo gdisk -> x -> z

它擦除整个分区并重新启动（我在liveusb上，所以我只需点击重启然后再进入后面的屏幕）

它重新启动我点击“其他东西”点击该分区使其合乎逻辑然后我做了挂载点/ 并点击继续它警告我关于交换但我继续并成功安装

重新启动后，我添加了锯片分区
