I've ubuntu 16.04 installed on my hard drive of laptop consuming total space of the drive. I would be installing 16.10 alongside that and so I was trying to make space available for the same. I deleted 2 partitions of the earlier installation namely /temp & /var. I did all this by booting from gparted bootable usb. Now I am unable to boot into my previous installation of 16.04. Grub menu is appearing, ubuntu logo is coming, then a terminal appears for 'maintenance'. I checked log via terminal and found 2 entries mentioning that those 2 partitions failed to be mounted.
I think the issue is due to those 2 deleted partitions although I'd shrunk root partition from the end part or end sector of the partition keeping the beginning sector the same. It has separate /boot partition which was untouched. Also I moved swap and home. As mentioned earlier I did via the bootable gparted USB.
As the issue may be because of deleting the 2 partitions, so will the issue resolve if I access the root partition via a bootable USB and remove the mount entries for the 2 partitions in the /etc/fstab file? I would like to say for rescue I've gparted live USB, Ubuntu 16.10 iso in my cell phone. That's all! Can the gparted bootable USB be used to create bootable ubuntu 16.10 USB?
How to proceed please?
