1 GRUB简介1.1 MBR和PBRMBR分为GRUB.MBR和DOS.MBR。由于硬盘上扇区从偏移0到偏移62属于同一个磁道0虽然DOS.MBR仅占用一个扇区但是需要将DOS.MBR后面的偏移1到偏移62保留所以磁盘上第一个分区的第一个扇区是从偏移63开始的。fbinst软件会保留1-16064扇区等于硬盘1个柱面的大小255 x 63 x 512 8MB所以第一个分区是从扇区16065开始的。USB-ZIP和USB-FDD会将U盘的第一个扇区格式化成DOS.PBR而不是DOS.MBR。USB-FDD和USB-ZIP的来历软盘的容量小没有分区结构所以软盘是没有MBR的整个软盘只有一个分区第一个扇区就是PBRFDD和ZIP模式在DOS下启动后U盘的盘符是A。1.2 GRUB- GRUB又叫OS Loader在Android系统上kernelflinger是OS Loader的一个EFI应用- GRUB镜像组成GRUB.MBRboot.img, 硬盘扇区offset 1 到offset 62放置GRUB的core.img/boot分区的boot/grub/grub.cfg1.3 创建USB-FDD或者USB-ZIP格式U盘步骤1Android上dd if/dev/zero of/dev/block/sda bs512 count42Windows上快速格式化该U盘这个U盘就只有PBR扇区而没有MBR扇区2 Windows安装2.1 BIOS设置进入BIOS设置一般有Del、Enter、Esc等键。2.2 Windows ISO刻录方法Windows上的Universal USB Installer工具软件刻录操作系统ISO文件到U盘Linux下将操作系统ISO文件刻录到U盘dd ifxxx.iso of/dev/sda 注意使用的是整个磁盘所以用的是sda而不是sda12.3 Windows GHO镜像安装方法 - 比较常见1) 制作PE启动U盘2) 下载Windows ISO镜像后番茄花园解压出来里面包含GHO文件拷贝到PE启动U盘的GHO文件夹或者提前将文件.gho拷贝入待装系统的电脑D盘根目录。3) 插入PE启动U盘到电脑USB 2.0口选择从U盘启动启动到PE界面后选ghost方式安装ghost镜像的后缀名.gho。2.4 Win10临时关闭驱动签名This PC - Advanced system settings - Advanced - Environment Variables开始 - 设置 - 更新和安全 - 恢复 - 点击右边高级启动项下方的立即重启进入高级启动 - 选择疑难解答 - 高级选项 - 启动设置 - 重启 - 再按数字键7或F7禁止驱动签名期间可能要求输入Bitlocker Recovery Key提前从如下的网址中获取或者在别人电脑登录获取。https://myaccount.microsoft.com/device-list2.5 Printer2.5.1 Printer1HP LaserJet M1005 MFP2Nantian PR9 并口-OKI仿真驱动2.5.2 Canon TS308 Cartridge - 20221220CL-846S Color, PG-845S Black.
