After reboot, the grub rescue screen i386 file not found, screen appeared.Hi @kushal140 nice to see you back ..Yes some people on here have several distro all on one disk. IN the old days we were limited by "primary partitions" of 4 if my memory serves me well and then "logical" partitions. With the new GPT the limit is beyond my wildest dreams . If Linux distros are installed on separate partitions they don't communicate with each other nor try to be incompatible. Its the boot loader that picks the one to boot up .
So out of interest did you get any joy with grub rescue ? and what has happened since you were last on ?
