After reinstalling Ubuntu again on the machine, the GRUB Rescue screen appeared as it says hd1 not a known file system. I did the following steps:set prefix=(hd0,gpt7)/boot/grubset root=(hd0,gpt7)insmod normalnormalThis led me to boot Ubuntu. And I did my GRUB update too. But the main problem was I have to enter the above steps in order to view the GRUB OS selection page. Can I avoid this steps and go directly to the main Grub Selection page?
