BIOS将控制权交给bootloader后,bootloader先执行boot.img部分,boot.img只负责跳转到GRUB2的diskboot.img部分,这部分加载GRUB2的其它未加载部分和用于文件处理的驱动到内存中。加载完后,GRUB2开始执行grub_main函数。grub_main函数完成初始化console、加载grub配置文件等任务后,调用grub_normal_execute函数,用于展示选择操作...
GRUB stands for Grand Unified Boot Loader. We’ll cover GRUB 2; there is also an older version now called GRUB Legacy that is slowing falling out of use. GRUB 是 Grand Unified Boot Loader 的缩写。我们将介绍 GRUB 2;还有一个旧版本,现在称为 GRUB Legacy,正在逐渐被淘汰。 One of GRUB’s m...
菜单一:MBR(grub2) --> kernel file --> booting 菜单二:MBR(grub2) --> boot sector(Windows loader) --> Windows kernel --> booting 菜单三:MBR(grub2) --> boot sector(grub2) --> kernel file --> booting 最终 boot loader 的功能就是“载入 kernel 文件”。 载入核心侦测硬件与 i...
grub2-set-default "CentOS Linux (3.10.0-123.9.3.el7.x86_64) 7 (Core)" 3、执行如下命令,确认配置成功。...2、在grub.conf文件中决定开机使用哪个内核版本做启动的参数是default,默认值为0,代表从最新的内核启动。代表启动的内核版本从上往下依次是0、1、2等。...3、如果要选择从旧版内核,即系统最开...
5.5.1 Exploring Devices and Partitions with the GRUB Command Line (使用 GRUB 命令行探索设备和分区 ) As you can see in Figure 5-2, GRUB has its own device-addressing scheme. For example, the first hard disk found is hd0, followed by hd1, and so on. But device assignments are subject ...
对于硬盘驱动器,MBR 加载一个阶段 1 启动加载程序,该程序通常是 Linux 系统上的 LILO 或 GRUB 阶段 1 启动加载程序。这是另一个 512 字节单扇区记录。 阶段1 启动加载程序通常加载一个记录序列,该序列通常称为阶段 2 启动加载程序(有时称为阶段 1.5 加载程序)。
This tutorial shows you how to install and use GRUB, the Grand Unified Boot Loader. Like LILO, GRUB allows you to boot your Linux system, taking care of loading and booting the kernel. Unlike LILO, GRUB is very feature-rich, much easier to use, much more reliable and flexible, and ...

Command-line access. Note:The tutorial below is written for GRUB 2, the current iteration of the GRUB bootloader. What Causes GRUB Boot Issues? The most frequent reason for GRUB not booting into the operating system involves another OS's bootloader overwriting GRUB boot configuration. Another caus...
如果安装PVE的时候文件系统选了ZFS,那PVE会用systemd-boot而不是grub,命令行去grub里改是没有效果的,得去/etc/kernel/cmdline。 内核/驱动 AER刷屏 如果延长线或者接口质量等导致pcie信号不太好,dmesg里可能会被AER(PCIE advanced error report)信息刷屏…… ...
