设备介绍：
DSM版本：918+ 主板CPU：蜗牛星际J1900板 内存：8G DDR3 固态：移速SATA固态（msata在win微桌面识别，群晖安装时候识别不到） 方式：SATA固态安装在硬盘盒上，左边左边第一个位置。其他盘取出
【1】修改引导盘配置文件：
插在电脑上（win10为例），注意有弹出格式化提示，不要格式化。linux系统盘，win不识别正常。打开三个盘里面正常那个盘
打开 boot / grub.cfg 用记事本编辑

核心点是这行，总的在两处 loglevel=15 DiskIdxMap=00 SataPortMap=1 SasIdxMap=0

保存，退出。
【2】bios 设置 windows8.x，（其实实测 windows7 也能刷，看教程要设置 8.x）
2.1 U盘启动盘，插主机箱后面 【黑色】 的usb上面。切记，一定是后面的黑色sub上，主板上的进不来bios，可以平时启动用
2.2 开机点按 F11 进bios页面。位置：Advanced->Miscellaneous Configuration->OS Selection

【3】设置 SATA Mode 为 AHCI。Port 1 设置 Enabled

【4】选择本地pat

下一步： 等待完成100%，会有倒计时10分钟（其实用不到那么久，差不多五分钟就好了）

【5】设置新的储存空间
储存管理器 – 新增储存池 – 新建空间
