??????? 拯救者刃7000K主机 i9-11900F RTX3070
? ? ? ? 主机的bios和笔记本的拯救者不同。
? ? ? ? 有问题请留言
1.安装ubuntu18.04系统
?????????说明：win11+ubuntu18.04
1.1 ubuntu18.04镜像地址（可以用迅雷等下载）：
????????Alternative downloads | Ubuntu
? ? ? ? 得到文件：ubuntu-18.04.6-desktop-amd64.iso
1.2 下载Rufus：
? ? ? ? Rufus下载地址：Index of /downloads
????????https://github.com/pbatard/rufus/releases
? ? ? ? 得到文件：rufus-3.17.exe（版本不固定）
1.3 制作镜像：
? ? ? ? 查看win11的BIOS模式：
? ? ? ? 键盘按win+r，输入msinfo32，可以看出本机为：UEFI
? ? ? ? 双击打开rufus软件，进行如下选择：（u盘会被格式化，注意备份）
????????
? ? ? ? ?准备就绪后弹出u盘，准备插到新电脑上。
1.4 磁盘分区
? ? ? ? win11的：搜索--磁盘管理，给win11留100G
1.5 关闭win11快速启动：
? ? ? ? 搜索--控制面板--硬件和声音--更改电源按钮功能--更改当前不可用设置--(取消勾选）启用快速启动--保存修改。
1.6 设置BIOS：
? ? ? ? 插入准备好的u盘；
????????重启，按下F1，进入界面：
? ? ? ? 选择More Settings
? ? ? ? secure?boot从disabled改为enabled
? ? ? ? ?First Boot Device由Boot Order改为USB HDD。
? ? ? ? 修改这两处后，按下F10，保存并退出。
1.7 安装ubuntu18.04
? ? ? ? 上面保存并退出后会进入安装界面
? ? ? ? ?选择第一个Try Ubuntu without installing或第二个Install ubuntu均可；选择第一个之后会进入ubuntu界面，在桌面上就有一个指向“install ubuntu”的快捷方式，同样可以进行安装。
? ? ? ? 这里选择第二个 install ubuntu，接下来是安装步骤
? ? ? ? 选择英语（也可以选择chinese），安装完成后也可以调整系统语言?
? ? ? ? ?选择正常安装：Normal installation和Download updates while installing Ubuntu
? ? ? ? 选择something else，和win11所在磁盘分开。?
? ? ? ? 下面是进行磁盘分区，考虑到/boot和/swap是必须的分区，这里将共分为三个分区/boot、/swap、/。
????????这里/home是存储用户个人文件的，一般意义上的“/”分区是存放计算机文件的，这里没有进行区分，具有较大的灵活性。能够让避免一开始给/home分区分的空间太小后来不够用且“/”分区有较大空闲----导致的空间利用率不高问题。
? ? ? ? 选中win11系统下划分的空闲磁盘分区：
? ? ? ? 点击左下角的“+”号，创建/boot分区。选Logical+Beginning of this space+/boot。
????????有的博客说的100MB够用，这里主要存放ubuntu系统的引导文件，有时候不小心点到的ubuntu更新，就会增加一些内核在这个位置，到时如果/boot分区满了，可以删除不必要的文件。我这里设置了500MB，一般200-300MB应该够用。
? ? ? ? 点击"+"创建/swap即交换空间分区，一般设为内存的2倍（让内存有时间休息下来，类似一半干活一般休息的意思）。我的内存为16GB，这里分区设为32GB=32768MB。选?Logical+Beginning of this space+swap area。
? ? ? ??点击"+"创建“/”，将剩下所有空间都给“/”。选Primary+Beginning of this area+/
? ? ? ? ?选择ubuntu安装引导分区即前面分的/boot分区，在下图的最后一行。弹出窗口后选择continue
? ? ? ? ?选择地区，这里选了上海，其他地方应该也行
? ? ? ? ?设置用户名、主机名和密码。注意用户名/主机名可以不一样，因为安装完系统后不容易修改，尽量这里设置一个比较合适的名称；密码尽量不要太长，因为进入系统后有很多需要输入密码的地方，太长容易耽误时间。?
? ? ? ? 接下来就是等待安装了：
?
? ? ? ? ?安装完成后会弹出这个界面，不要重启，“×”掉，然后选择关机；关机后将u盘拔掉，再开机。?
? ? ? ? ?开机界面如下，说明安装成功了
