ACER Nitro AN515-54 WIN10 + Ubuntu 16.04双系统

ACER 笔记本, 型号如标题.
自带512G SSD + WIN10 系统.
+ 机械硬盘 1TB
+ 8GB DDR

笔记本后盖不是拆分式的, 无法单独安装内存和硬盘, 只能整盖拆除, 无它, **卸完螺丝后, 暴力拆解**.
建议硬盘装上后不打螺丝, 刚开始装上, 但后面发现空间太紧, 挤压到硬盘, 甚至还发出异响, 差点把硬盘烧坏了.
*PS, 本想送去技术服务站安装, 可惜, 态度不热情, 100RMB不开发票, 距离远.

1. 开始时没有加机械硬盘, 无法识别到SSD硬盘
  安装时报错: No root file system is defined
  可以通过修改BIOS解决(Main > SATA Mode > AHCI), 但这样, 就无法保留原来的WINDOW, 这部分没实际操作, 不作说明.
2. 安装ubuntu 18.04 后
  尝试编译RK3288 Android 7.1源码, 出现新问题:

Lex: aidl <= frameworks/base/tools/aidl/aidl_language_l.l
flex-2.5.39: loadlocale.c:130:_nl_intern_locale_data: ?? 'cnt < (sizeof (_nl_value_type_LC_TIME) / sizeof (_nl_value_type_LC_TIME[0]))' ???

make: *** [out/host/linux-x86/obj/EXECUTABLES/aidl_intermediates/aidl_language_l.cpp] 已放弃 (core dumped)

最后, 因无法解决openjdk-7安装兼容问题 和 安装virtulbox-6.0 放弃使用18.04, 装回16.04
已尝试的openjdk-7兼容安装方法:

https://askubuntu.com/questions/761127/how-do-i-install-openjdk-7-on-ubuntu-16-04-or-higher

1. 开机时重复按F2 进入BIOS.
2. 切到 Security > Set Supervisor Password: 输入密码: ****, 方便后面设置, 密码请谨记.
3. 切到 Main > F12 Boot Menu, 高置为 Enabled, 使能F12显示开机项
4. 启动时按F12显示开机启动菜单

WIN10 与 Ubuntu切换方法: 开机时按F12, 会有两个选项, 选择Windows 或 Ubuntu即可.
