我的分区和wiki分区有点不同，装的双系统，archlinux安装分区是从win扩展分区划出的。所以分区设置的逻辑分区，我不确定linux分区是否需要boot，所以未设置。

/dev/sda1 boot id 7
/dev/sda2 id f
/dev/sda5 id 7
/dev/sda6 id 7
/dev/sda7 id 7
/dev/sda8 id 83
/dev/sda9 id 83

怎么解决grub 找不到linux的问题。

这句不是说没找到archlinux，这句可以无视掉
这句是因为什么lvm那玩意闹的，
当初我的ubuntu也会有这句，卸载了lvm的包好了

Found linux image: /boot/vmlinuz-linux
Found initrd image: /boot/initramfs-linux.img

这两句已经说明找到了archlinux

多谢，重启后，有archlinux
昨天第一次装archlinux失败，所有看到警告就晕菜了
