启动到ArchISO
将系统重装为 Debian 10，然后安装 grub-imageboot
# 安装 grub-imageboot apt update -y && apt install grub-imageboot -y # 新建文件夹用于存放ArchISO mkdir /boot/images # 进入文件夹 cd /boot/images # 下载镜像 wget http://mirrors.tencentyun.com/archlinux/iso/2021.12.01/archlinux-2021.12.01-x86_64.iso # 可选镜像 wget https://mirrors.ustc.edu.cn/archlinux/iso/2021.12.01/archlinux-2021.12.01-x86_64.iso wget http://mirror.rackspace.com/archlinux/iso/2021.12.01/archlinux-2021.12.01-x86_64.iso
配置grub
# 更新grub update-grub2 # 按照上面的提示，选择默认启动项，我这里是ArchISO是第三项 vim /etc/default/grub # 从0开始，所以这里是2 GRUB_DEFAULT=2 # 更新grub udpate-grub2 # 重启等待即可，登录到VNC reboot
