I want to see all everything in booting like what is being loaded and all instead of grub purple Interface.. So is there any way to enable text kind of mode and disable that purple screen ??
sudo gedit /etc/default/grub. Look for the line that reads:
GRUB_CMDLINE_LINUX_DEFAULT="vesafb.invalid=1 splash quiet"
splash quiet part (yours might be different, so don't change anything but that). Save the file.
sudo update-grub. Reboot, no more purple screen.
Temporal (one time)
In the boot menu, press E. Look at the end of the line starting with
splash quiet. Remove
splash quiet (do not touch anything else) press Ctrl + X. No purple screen.
