我在启动我的笔记本电脑 Acer Helios 300 2019 时遇到了奇怪的事情：
我刚刚在新的 SSD 上安装了新的 Ubuntu 18.04.4 LTS。在 SSD 上安装过程中，我没有格式化已有 Ubuntu 的现有 HDD。
在 SSD 上安装了新的 Ubuntu 后，启动时会出现 GRUB 让我选择要启动哪个 Ubuntu（从 SSD 还是 HDD）。
我选择从SSD启动。
在SSD的Ubuntu中，我使用GParted格式化HDD。
我更新了 GRUB 以确保它删除了过时的信息。
sudo update-grub执行此操作后，GRUB 在启动时不再出现，但奇怪的事情发生了：Predator 徽标（来自笔记本电脑制造商）在启动时出现两次。两次之间正好是 10 秒的类似于 GRUB 的紫色屏幕，但菜单 GRUB 实际上并未出现。
问题记录链接在这里：

我怀疑我对 GRUB 做了一些错误操作。有人能帮忙吗？（我刚接触 Ubuntu 几天）。谢谢。
更新：我修改了我的 Grub 文件如下：
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_DISABLE_OS_PROBER=true
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"
GRUB_CMDLINE_LINUX=""
紫色屏幕仍然出现。以下是输出cat /boot/grub/grub.cfg
