Ashu's questions

我有 Windows 11 和 Ubuntu 22.04 LTS 双启动系统。Windows 11 在普通 SSD 上，而 Ubuntu 22.04 LTS 在 PCIE NVME SSD 上。它是 Dell XPS 8930 Desktop(2018)，我在那里做了很多升级和添加。作为最新升级的一部分，我将 512GB PCIE NVME SSD（版本 1）升级到了 4 TB PCIE NVME SSD（版本 4.0）。我为此使用了傲梅克隆软件。在升级 PCIE NVME SSD 的过程中，我删除了交换分区，因为它不再被使用了。磁盘克隆成功。之后，我将桌面上的旧 PCIE NVME SSD 换成新的 PCIE NVME SSD。

双启动 - Windows 和 Linux 都可以正常启动。但唯一的问题是这张支票在那里。过去我也进行过此检查，但它是一个较小的 PCIE NVME SSD，但现在它用于较大的 PCIE NVME SSD。

消息如下：SGX Launch Control 已锁定。仅支持 SGX 虚拟化。我相信这可能是因为我在 BIOS 中启用了虚拟化。这个消息很快。但在那之后它是一种检查磁盘的过程。我的 PCIE NVME SSD（安装了 Ubuntu 22.04 LTS 的是 4TB）所以这种检查磁盘类型的检查确实减慢了启动过程。我如何禁用这种检查磁盘的过程。

也尝试过这种方法但没有成功。也尝试过这种方法但没有成功。这是这个问题的视频

我认为这可能是潜在的问题

我有一个双引导系统——Windows 11 和 Ubuntu 22.04 LTS。常规 SSD（2.5 英寸）上的 Windows 11 和 PCIe NVME Gen 1 上的 Ubuntu 22.04 LTS - 512 GB。随着 PCIE NVME 价格下降和我对 linux 的使用增加，我为我的 linux 买了另一个 PCIe NVME Gen4 4 TB 驱动器。我的台式机主板仅提供一个 PCIe NVME 驱动器，这意味着我需要将 512 GB PCIe NVME 克隆到 4 TB PCIe NVME。过去有人这样做过吗？有什么需要照顾的吗？我的 Linux 安装很简单 - / 和交换分区，没什么特别的。正在通过此链接，但似乎对此没有太多讨论。

Windows 10 是默认操作系统，但是当我选择 Ubuntu (20.04 LTS) 时，它根本没有加载。Ubuntu 安装在单独的 NVMe 驱动器上，驱动器一切正常：

选择Ubuntu后，它更进一步，然后黑屏。屏幕左上角有一个闪烁的光标，就是这样。可能是什么问题？在过去 3 个月中 - 我已从 Nvidia GTX 1060 6GB 卡切换到 Nvidia 1050Ti 4 GB 卡。即使在那次切换之后，Ubuntu 也总是运行良好。可能是什么问题？

我已经有 3 个多月没有登录 Ubuntu 了，在过去的几个月里，Windows 更新了很多次。我没有将我的 Windows 10 升级到 Windows 11。

更新 1： 在 live-usb 启动后尝试启动修复（“尝试 Ubutu） - 它表示启动修复工作正常，但是当尝试在 Ubuntu 中再次重新启动时......相同的黑屏，光标闪烁。这是pastebin引导修复中的位置这些是进一步的说明

开机成功修复。

You can now reboot your computer.
Please do not forget to make your UEFI firmware boot on the Ubuntu 20.04.1 LTS entry (nvme0n1p2/efi/ubuntu/grubx64.efi file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

更新 2 我能够通过恢复模式启动，但随后启动 Ubuntu Linux 无法正常工作。我只能通过恢复模式启动到 ubuntu。

更新 3 全新安装的 Ubuntu Linux。即使这样也没有成功。在安装 nvidia 显卡驱动程序方面存在问题。恢复模式安装并尝试“安装损坏的软件包”并收到此错误。 所以最后我进入了额外的驱动程序并开始使用 nvidia-470（专有和测试）驱动程序。之后它工作正常。

我正在更换我孩子台式电脑的机箱和 PSU。这是 2015 年 HP 台式机 - 英特尔四核计算机。很多部件和升级都在它上面进行，最新的是 GPU（Nvidia 1005 Ti）——所以它是为了更换 PSU 和外壳（为了更好的气流）。它有 5 个 SATA 端口 - 因为新机箱没有 5.25" 托架 - 所以无法使用 DVD 驱动器。它有两个 SSD 和一个 3.5 英寸硬盘驱动器。我没有拍下 SSD 和硬盘的照片驱动器已连接在此主板上. 一切都在几个小时内完成，但我们收到此错误 POST BIOS: No boot disk has been detected or the disk has been failed。尝试了各种组合来连接主板上的硬盘驱动器和 SSD - 错误不会消失。我拿出SSD，发现SSD（500 GB）有Windows，SSD（1TB）-只有Windows D驱动器或数据，而3.5英寸硬盘是Ubuntu Linux。我不知道我们上次创建双引导是什么时候 - 安装了 GRUB 或 LILO。我儿子根本没有使用 Ubuntu，所以我们可以负担得起卸载/删除 Ubuntu Linux 并在需要时安装它。我以某种方式登录到那台计算机并创建了 Windows 恢复媒体（在 USB 上）。现在我如何卸载 Ubuntu 和 GRUB/LILO 使其成为纯 Windows 计算机？

我将在那台计算机上安装 Ubuntu Linux，稍后当孩子对 Ubutnu linux 产生兴趣时。

我按照这个 删除了 Ubuntu 20.4.1 LTS 和 grub2 - 获得最多支持的答案。之后 grub2 黑屏消失了，但 Windows 10 没有启动。

更新1

我使用 live USB 登录，然后尝试启动修复。遵循它的所有建议。它试图重新安装 grub2，所以似乎在我的计算机上安装了另一个 Ubuntu Linux 20.4（我有 1 个安装了 Ubuntu Linux 的 NVME PCIe 驱动器 - 我删除了它，然后是安装了 Windows 的 1 个 SSD，即 Windows C 驱动器和然后是 Windows D 和 E 的两个硬盘驱动器）。似乎在 C、D 或 E 上的某个地方 - 安装了 ubuntu linux，我想摆脱它或移动到 PCIe NVME 驱动器这是引导修复输出链接和引导修复活动的内容：

You can now reboot your computer.

Please do not forget to make your UEFI firmware boot on the Ubuntu 20.04.1 LTS entry (sdb2/EFI/ubuntu/shimx64.efi file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.

If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi

这是我的 Ubuntu Linux 20.4 LTS 的 gparted 视图

不知何故，在其他地方安装了隐藏的 Ubuntu 20.4 LTS，这使我的 grub 启动到 Ubuntu 20.4 LTS Linux。

更新2 经过一番搜索和挖掘，发现在/dev/sda7上安装了另一个Ubuntu Linxu 20.4.1 LTS的副本

并通过df命令确认

更新 3 即使从 Windows 删除 /dev/sda7 分区然后删除 /EFI/ubuntu - 我也无法启动 Windows 10。因此使用live USB驱动器将重要数据从Windows C：复制到Windows D：后来使用Windows恢复驱动器将Windows重新安装在C：驱动器上。我本可以将它安装在其他驱动器上，但我的 C: 是 SSD，我更喜欢在更快的媒体上安装操作系统和应用程序。

我的戴尔 XPS 9560 有一些不稳定的 wifi 连接问题。连接经常掉线或非常慢。

试过这个

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info &&
  chmod +x wireless-info &&
  ./wireless-info

这是我的 pastebin 内容 但没有改进 - 可能是什么问题？当我启动到 Windows 10 时 - 相同的 wifi adator 运行良好。

我有一台戴尔 XPS 15-9560 笔记本电脑，配备 15.6 英寸 4K 超高清 (3840 x 2160) IGZO IPS 350 尼特触摸屏和 NVIDIA GeForce GTX1050 4GB GDDR5。它具有 4K 分辨率。从 grub 屏幕到 Ubuntu，它字体非常小。有什么办法可以增加字体大小吗？

这是一台非常好的笔记本电脑 - 真正的 MacBook Pro 杀手……越来越受欢迎……我可以看到很多人都会遇到同样的问题。

编辑 1

我搞砸了我当前安装的 ubuntu desktop 18.04 LTS，不得不重新安装它。现在刚刚尝试了这个：将 nouveau.modeset=0 添加到启动参数对于较小的字体来说是更好的解决方法，我现在有更好的分辨率。到目前为止，它比其他解决方案要好得多。

似乎 ubuntu18.04 LTS 与以前的版本相比，Nvidia 显卡的问题并不稳定且复杂得多。

我正在尝试在 Windows 10 旁边安装 Ubuntu Desktop 18.04 LTS，但它没有检测到我的Samsung EVO 960 PCIe NVME SSD(500 GB)。从 Windows 10 专业版中可以看到和使用相同的内容。可能是什么问题？

而不是直接安装。首先，我进入“尝试不安装模式”并打开 gparted...gparted 显示 SATA SSD、其他硬盘驱动器、USB 驱动器，但不显示三星 PCIe NVME SSD。

我的可启动 ISO 映像中还需要其他什么来检测 PCIe NVME SSD？我的 BIOS 模式是 UEFI（这是安装 Windows 的模式），是这里提到的问题吗？我的是戴尔 XPS 8930 台式机 - 英特尔酷睿 i7-8700（6 核处理器，64 GB RAM，Windows 安装在 SATA SSD 上，我正在尝试在 PCIe NVME SSD 上安装 ubuntu Linux 18.04 LTS）。

编辑 1 我没有尝试 Ubuntu，而是继续安装，但最终出现了一些错误……Ubuntu 无法检测到我的计算机上的 Windows 10 安装…………似乎 18.04 LTS 还为时过早尝试出来。

编辑 2 在 Internet 上搜索戴尔 XPS 台式机/笔记本电脑特定问题并找到以下链接： link1 link2 link3

进入 BIOS(F2) 并在保存此设置时将 BIOS 更改 为SATA settingBIOS 警告我可能无法启动我的操作系统 (Windows 10) 或者我需要重新安装它。我继续...几次...在 BIOS 级别重新启动...操作系统从未出现...最后 BIOS 进入健康检查和恢复模式...我将设置恢复为至少Windows 10 能够启动。RAID OnAHCIRAID On

对于双启动 Linux 或 PCIe NVME 驱动器，戴尔的 BIOS 似乎并不那么容易使用它似乎......将在周末晚些时候尝试。

Edit3 不知何故，Ubuntu 安装程序无法检测到 Windows 10。进一步谷歌搜索，然后将 BIOS 更改回启用安全启动和启用 UEFI。现在 Ubuntu 安装程序能够检测到 Windows 10。在我闪亮的三星 PCIe NVME SSD 上安装成功，没有任何问题。

我试图遵循这个问题，但不是很清楚该怎么做？就我而言，我的分区看起来像这样

我想从挂载为“/”和 ext4 分区的 /dev/sda4 中释放一些空间。一旦我得到这个可用空间，我想登录 Windows 以将可用空间分配给 Windows 分区（C:) /dev/sda3。

现在我的“/”有 234 GB。我只想将其减少到 100 GB，以便可以将剩余的 134 GB 添加到 Windows 分区。

当我使用 gparted 时，我没有选择按下调整大小按钮，因为它是灰色的……为什么？

我需要先卸载它..在这种情况下 Ubuntu 会工作吗？

我真的需要使用 live USB 来完成这项工作吗？由于这是 Linux 分区，因此我只想从 Linux 中进行操作……当向 Windows 添加更多空间时……在这种情况下，我将使用 Windows 工具（请提出建议）。

感谢大家的意见/建议。我也在关注这个链接 在使用 live USB 之后，gparted 缩小 /dev/sda4 现在当增加 Windows（/dev/sda3）时 - 我遇到了问题，我必须移动缩小的 /dev/sda4 为 Windows 腾出相邻的空间（/开发/sda3)

进行这两项操作时，还收到一条警告消息...

让我们看看发生了什么？

更新 能够将 Linux (/) 缩小到 111 GB 并将其向右移动以为 Windows (C:) 让路。还能够扩展 Windows(C:) 以添加剩余的 GB。

在此之后，我的 grub 无法正常工作，这需要我使用boot-repair. 在此步骤中 - 我需要执行以下命令：

sudo dpkg --configure -a
sudo apt-get install -fy
sudo apt-get purge -y --force-yes grub*-common grub-common:i386 shim-signed linux-signed*
sudo apt-get install -y --force-yes grub-efi-amd64-signed shim-signed linux-signed-generic

最后是粘贴箱内容

有很多不必要的 EFI 条目，我可以按照我的策略进行修复。

然后grub-customizer修复引导顺序

现在一切正常。这里看起来像在这个操作之后

我已经让 Windows 10 和 Ubuntu Linux Desktop 14.04 LTS 运行良好。后来我添加了另一个驱动程序并且无法使用LVM来使用Ubuntu的第二个驱动器的提醒。这就是为什么我认为最好在 14.04 上安装 Ubuntu 16.04 在获得正确的 .iso 文件并使用它之后......我尝试这样做并选择了其他东西......无法弄清楚如何在安装时使用 LVM时间......我试图退出安装......幸运的是，我有 Windows 的救援磁盘并进行了备份......但在两者之间退出 linux 安装后......我被 grub 救援卡住了屏幕。

Minimal BASH like line editing is supported. for the first word, TAB lists possible        command completions. anywhere else TAB lists possible device or file completions.

然后我单击 Tab 并显示：

Possible commads are: [authenticate badram boot break clear configfile continue cutmem echo export extract_entries_configfile extract_entries source gettext initrd insmod linux loopback is menuentry normal normal_exit probe return search search.File search.fs_label search.fs_uuid set setparams shift source submenu terminal_input terminal_output test unset.

有点像......这个链接和这个链接对我不起作用......

我有 /dev/sda7 作为我的 '/' 和 /dec/sda6 作为交换，而 /dev/sda2 是 /boot/efi 和 /dev/sdb3 作为 LVM2 PV...

在 grub 救援中，我可以弄清楚我的“/”在哪里

ls (hd0,gpt7)/

节目

boot/
etc/
opt/
mnt/
root/
usr/
var/

ETC...

该怎么办？请帮忙。

尝试了这些解决方案 #1 #2

但没有成功......我得到了想要的结果（根据那些博客）但我仍然只能进入 grub 救援模式......没有办法

即使从 Windows 命令提示符尝试了这些命令（使用恢复媒体和故障排除之后）

BOOTREC /SCANOS
BOOTREC /FIXMBR
BOOTREC /FIXBOOT
BOOTREC /REBUILDBCD
bootsect /nt60 SYS or bootsect /nt60 ALL

没有影响...我只是坚持使用 grub 救援模式。在 USB 媒体中找不到任何 .iso 以跟随其他链接。

更新

尝试使用 Windows 10 恢复媒体 (USB) 并将计算机也重置为出厂模式...将 secureBoot 设置为禁用，将旧启动支持设置为启用并禁用快速启动...仅使用 grub 命令行菜单...（ hd0,gpt7) 包含我的根 (/) 和 ubuntu Linux 的其他分区...但是 sudo mount 等...不起作用...甚至无法擦除 Ubuntu 并将其安装到 Windows 10（计划安装Ubuntu Linux 桌面 16.04)

也将问题发布到微软社区。

想要完全删除 Ubuntu 14.04 并使用恢复媒体重新安装（恢复）Windows 10。安装 Windows 10 后，我想安装 Ubuntu 16.04 LTS。

更新 现在收到此错误...我仅使用 Windows 10 中的恢复 USB 驱动程序...它应该可以工作...但无法正常工作...我如何才能完全清除我的整个硬盘驱动程序内容并确保Windows 恢复驱动器正在恢复我的 PC...如果需要，我已准备好释放数据。

现在 Windows 10 恢复也没有发生。我永远卡在这个屏幕上。

不知何故使用了 Ubuntu Live USB(16.06 LTS)...尝试 ubuntu，这就是它在 gparted 中的样子。

这是pastebin的内容

更新（2016 年 5 月 5 日）

就我而言，即使是os-uninstaller也无济于事。

由于此处提到的 wifi 问题，我必须按照以下命令将内核升级到 4.2.x：

$ cd /tmp  
$ wget \  kernel.ubuntu.com/~kernel-ppa/mainline/v4.2.5-wily/linux-headers-4.2.5-040205_4.2.5-040205.201510270124_all.deb \  kernel.ubuntu.com/~kernel-ppa/mainline/v4.2.5-wily/linux-headers-4.2.5-040205-generic_4.2.5-040205.201510270124_amd64.deb \  kernel.ubuntu.com/~kernel-ppa/mainline/v4.2.5-wily/linux-image-4.2.5-040205-generic_4.2.5-040205.201510270124_amd64.deb  
$ sudo dpkg -i linux-headers-4.2*.deb linux-image-4.2*.deb

我知道我可以使用以下方法删除它：

sudo apt-get remove linux-headers-4.2* linux-image-4.2*

这解决了我的 wifi 驱动程序（Intel wifi 3165）问题。但是我了解到我是从主线获得内核的，这不是一个好主意，因为我不会再获得任何更新等……那么升级内核的正确方法是什么？我听说我应该使用：

sudo apt-get install linux-generic-lts-wily

想知道我需要做什么才能正确升级内核吗？对我来说，如果我没有这个内核版本，我的 wifi 就无法工作，这非常重要。此外，想知道当新的 LTS 版本（16.04 LTS）在 2016 年 4 月推出时，我的 Ubuntu Desktop 14.04.3 LTS 和这个升级的内核会发生什么？

我还有另一个限制：我需要使用 LTS 版本，因为我使用的一些软件工具/产品（DSE 和 RLEC） - 仅需要 14.04.3 LTS 版本。这就是为什么不能去 15.10

我在我的台式机和笔记本电脑（都运行 Ubuntu Desktop 14.04.3 LTS）中运行 RedisLabs Enterprise Cluster。在我的桌面上 - 如果我重新启动，RedisLabs Enterprise Cluster 会停止，但如果是我的笔记本电脑，它不是吗？如何停止 RLEC 服务？两者的唯一区别是笔记本电脑 - 我已将内核版本升级到 4.2.5，而台式机仍然是 3.1 或 3.2 上次我通过完全卸载 RLEC 解决了这个问题。

我可以杀死其中一些进程，但这并没有多大帮助。

我正在使用一个新的硬盘驱动器（非 SSD，普通旧硬盘驱动器），它已经 ext4 格式化并在阅读本文后安装在 /media/mynewdrive

但是我想将它安装在 /opt 因为大多数软件都安装在那里。目前我需要手动将这些东西移动到 /media/mynewdrive 和下面......不是很方便记住的位置......我该怎么办？我的旧驱动器中已经有 /opt 和子目录，我想保持原样。这是我当前的挂载命令输出：

这是 500 错误，但当我访问这个位置docker 分布时

我可以看到一些文件...我应该直接从那里安装吗？根据您过去的经验有什么建议吗？

root@ashu-HP-ENVY-Notebook:/home/ashu# uname -r
4.2.5-040205-generic

我正在使用 linux kernel 4.2.5 基本上安装 docker 没有用，有什么帮助吗？

我正在使用 Ubuntu 桌面 14.0.4。由于某些原因，我需要升级到内核 4.2.5。但在那之后，VMWare Player（我相信版本 12.x 64 位 linux）无法正常工作。在启动时，它正在尝试为新内核编译模块。我卸载了它并重新安装了 VMWare Player，但同样的问题。它正在寻找不可用的特定版本的 gcc。

调查了这个线程还有另一个线程 ，但无法找到 gcc-5.2.1 版本。也无法卸载以前版本的 gcc

这是我当前版本的 gcc

我在具有 Nvidia GTX 950M 图形驱动程序的 HP Envy Slim 笔记本电脑上使用带有 Linux 内核 4.2.5 的 Ubuntu Desktop 14.0.4。一切正常，但我想确保我使用的是正确的图形驱动程序？

我使用以下步骤来获取它：

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-352
sudo reboot

我正在尝试关注此线程：询问 Ubuntu：如何安装 Intel Dual Band Wireless-AC 3165 驱动程序？

但是，我无法iwlwifi-7265D-13.ucode从任何地方获得正确的 ucode 文件。

我正在运行 Ubuntu Desktop 14.04 LTS 并遇到无法配置英特尔 wifi 卡 3165、wifi 驱动程序的英特尔链接的问题

仅从内核 4.1 开始支持此 wifi。我在通用 3.19。我应该将这个 wifi 驱动程序的内核升级到 4.1 还是 4.2？

我担心的是我需要使用仅适用于 ubuntu 14.0.4 LTS 的 Datastax Enterprise cassandra 和 Redis Labs Enterprise 集群。因此，如果我升级内核 - 它们可能无法正常工作？我有哪些选择？

我在英特尔酷睿 I7 上使用 Ubuntu 15.10 桌面版 - 64 位版本 - 具有 16 GB RAM、4 GB 显卡（Nvidia GTX 950M）的四核笔记本电脑。成功安装后 - 由于 Ubuntu 的内置和默认图形驱动程序不够好，Ubuntu 冻结。我继续从 http://www.nvidia.com/Download/driverResults.aspx/84043/en-us安装了“Nividia GTX 950 M 驱动程序”

并点击此链接 How do I install the Nvidia driver for a GeForce GT 630

成功安装 Nvidia 显卡，但在登录时出现登录循环（unity 和 lightdm）。

我已经检查过它只是加载了 nvidia 驱动程序，并且 nouveau 被禁用（或未加载）。我仅从 nvidia 网站获得的 nvidia 驱动程序。

我试图安装 Nividia GTX 950 M 驱动程序。为此，我需要执行 Ctrl+Alt+F1，然后停止 XWindows（sudo service lightdm stop）。它停止了，然后我开始运行 Nvidia 驱动程序的安装。一旦驱动程序安装正常 - 它要求我重新启动笔记本电脑。在统一登录屏幕上的笔记本电脑后，我的密码不起作用。我检查了所有内容-大写锁定等....但它只是不工作....如果我同时按Ctrl + Alt + F1 - 相同的密码正在工作。使用命令检查我安装的 Nvidia 显卡时

less /var/log/Xorg.0.log | grep 'vendor'

我可以发现它已经正确安装了 Nvidia 图形驱动程序并卸载了默认的“Nouveau”驱动程序。

我想知道……出了什么问题……如果我按 Ctrl+Alt+F7 - 我的密码不起作用……会出什么问题？

我正在使用 Ubuntu 14.0.4 桌面 - 英特尔酷睿 I7 上的 64 位版本 - 具有 16 GB RAM、4 GB 显卡（Nvidia GTX 950M）的四核笔记本电脑

我查看了整个互联网上的各种问题。事实上，差不多 6 个月前，我在我的惠普台式机上做了同样的事情，但我做了太多的尝试和尝试，以至于我忘记了这次该做什么？我需要做其中的任何一个或全部或具体做什么吗？在 BIOS 中禁用安全启动？在 Windows 8.1 中禁用快速启动？禁用 UEFI 引导并启用传统引导？

我需要做什么？最重要的是，我不知道到底需要做什么？互联网论坛上有很多博客和内容，答案非常混乱。
