我想在我的双启动 acer 上扩展 Ubuntu 18.04 的磁盘。一切运行顺利，但它需要一些额外的空间，因为我最初只给了它 20 GB。
所以我在 Windows 磁盘管理器中又切出了 40 GB。在 Linux GParted 中，我将磁盘添加为sda7ext4 并挂载它。但是当我想安装某些东西时，它并没有像我预期的那样运行，因为仍然没有足够的空间。
从那以后，我真的搞砸了。我按照以下步骤重写了分区表：https://www.ryadel.com/en/resize-extend-disk-partition-unallocated-disk-space-linux-centos-rhel-ubuntu-debian/
重启后仅转到 GRUB 2.04。

有人能建议如何再次启动 Ubuntu 吗？我发现sda6缺少引导扇区类型等。有人能建议如何修复吗？
答案1
抱歉发了不必要的帖子。幸运的是，我准确地记下了两个分区的开始和结束块。使用 live usb ubuntu，我将分区表反转回来。从此，linux 照常从磁盘启动。之后，我使用 live usb 和工具 gparted 将未分配的 40 GB 磁盘合并到安装了 linux 的现有 20 GB 磁盘。gparted 成功移动文件，重启后，我有 60 GB 可用于 linux。
