You cannot be slipshod and expect it will auto-correct for you.
Yes, I figured out that I made a mistake there. I corrected and tried again but it did not get well. The booting fell into a shell after waiting 30 seconds as its mentioned here
then I tried the steps mentioned there
mount /dev/sda2 /mnt
mount -o loop /mnt/boot/images /KaOS-2020.05-x86_64.iso /iso
now it worked, I could boot into the live system and I installed the KaOS. kool but some things I like to mention, that once I rebooted the machine, my other grub menu entries are gone !
I have MXLinux installed in my sda2 now I have no option to boot there. Any idea how to ?
And your isofile name "kaos-2020.05-x86_64.iso"
Are you sure it is not "KaOS-2020.05-x86_64.iso" ??
I actually renamed the ISO file into all smaller cases then only I used it on my menu entry but yes It did not work anyway, so I reverted all back.
now, please help me to how do I get my other OS boot entry back
