[Bug 1480703] Re: grub-install defaults to /dev/mmcblk0

[carlostipton1319]

As a user, encountering an issue where "grub-install" defaults to
"/dev/mmcblk0" instead of "/dev/sda" can indeed cause installation
failures on laptops that have an SD card. The preference for
"/dev/mmcblk0" over "/dev/sda" can lead to incorrect bootloader
installation and system booting issues.

To address this problem, you can try the following steps:

Disconnect the SD card: Before running the installation process, try
removing the SD card from the laptop
