tag-icon • tag-icon boot dual-boot grub2 upgrade

我已经成功运行 Windows 10 和 Ubuntu Linux 18.04 LTS 系统近 2.5 年了。然后听说 20.04 LTS - 似乎安装得很顺利 - 我想尝试一下。我点击了以下链接：如何将 Ubuntu 18.04 LTS 升级到 Ubuntu 20.04 LTS。 从命令行完成所有操作。一切顺利。我在 PCI NVME SSD 上安装了 Linux，在普通 SSD 上安装了 Windows 10。我使用 Windows 引导加载程序作为默认条目，如果我想使用 Linux，则选择 Ubuntu Linux。根据该链接，我安装了不使用内核来清理一些空间。我得到了紫色的 grub 屏幕。

但升级之后，出现了这个黑色的 grub 屏幕。在此处输入图片描述在哪些 Linux 上 - 有两个条目 - 我不知道哪一个是默认的。但如果我尝试选择其中一个 Linux - 它不会启动 Linux，而且全是黑屏。

虽然在 Grub 上 - 我可以选择 Windows 的条目，并且它可以毫无问题地启动它。

哪里出错了？如何使用升级后的 ubuntu Linux 20.04 LTS 恢复正常生活？我可以选择高级选项，然后尝试启动 5.4.0-31-generic（Ubuntu Linux 20.04 LTS 附带的内核）之后它显示：正在加载 Linux 5.4.0-31-generic...正在加载初始 ramdisk...然后卡住/冻结。在此处输入图片描述 在此处输入图片描述

可能是什么问题？但在选择 Ubuntu 的高级选项后，当我选择 Ubuntu Linux 4.15.0-101-generic 它向我显示了相同的消息正在加载 Linux 4.15.0-101-generic…正在加载初始 ramdisk…但没有卡住或冻结，最后加载了新的 Ubuntu Linux 20.04 LTS

这是怎么回事？我检查了 20.04 LTS 是否已安装并可以使用此选项 root@ashu-XPS-8930:/home/ashu# cat /etc/lsb-release

cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=20.04
DISTRIB_CODENAME=focal
DISTRIB_DESCRIPTION="Ubuntu 20.04 LTS"

并且 Linux 内核的版本仅为 4.15.0-101-generic

root@ashu-XPS-8930:/home/ashu# uname -r 
4.15.0-101-generic

似乎已经存在漏洞升级时还是上次更新没有做好

更新 我尝试安装其他各种内核，认为可能会解决这个问题，但没有成功。 在此处输入图片描述

答案1

您是否再次尝试了步骤 2（删除内核）？

步骤 2）删除未使用的内核并安装“update-manager-core”

重启后，一旦 Ubuntu 18.04 LTS 桌面可用，建议删除未使用的内核以释放 /boot 分区的空间，运行以下命令：

pkumar@LinuxTechi:~$ sudo apt --purge autoremove

答案2

请参阅我的问题和答案删除了 Ubuntu 和 grub 但 Windows 10 无法启动。

不知何故，对于我来说，双启动 Windows/Ubuntu - Ubuntu 从以前的 LTS 升级到新的 LTS 版本从未成功过。当我尝试将双启动 Windows 7 或 10/Ubuntu 16.04 LTS 升级到 Ubuntu 18.04 LTS 时也发生了同样的情况。在原地，Windows 升级工作正常。

比修复此问题更好的是全新安装或保留 18.04 LTS。
