首先默认是安装win10系统然后在安装centos

一个硬盘两个系统：

首先将磁盘压缩出40个G出来

磁盘管理

然后分出40G压缩卷。

两个硬盘两个系统：

如果是两个硬盘就在win10的盘符下分出1024MB压缩卷，注意系统引导要在win10的盘符下。也就下面自定义centos7

安装的时候分卷的boot目录它的安装地址是在win10的硬盘上也就是分出来的1024MB空间，其他分卷安装在另一个硬盘上。

其他：

win10安装就略过

linux注意：

1.选择自定义安装

2.设置分区

一个盘：

如图所示boot目录在一个盘是默认在同一个盘分出的40G压缩卷

如果是两硬盘就是boot放在win10硬盘分出的1G压缩卷。其他放在第二个硬盘下面

注：

swap：是内存缓存，一般是内存1~2倍。

其他和正常安装centos一样。

安装完成必然在启动页面没有win10启动选项

解决办法

yum update

yum install epel-release

yum install ntfs-3g

grub2-mkconfig -o /boot/grub2/grub.cfg

设置第一启动项为win10

#找文件
find /boot -name 'grub*.cfg'

找到然后修改grub.cfg

然后在修改grub

vim /etc/default/grub

#第一项是win10 所以设置为0
GRUB_DEFAULT=0

最后

reboot
