As is my habit, I was tweaking my ubuntu laptop and I deleted one unused partition. Then I continued working on the system. After I while I turned off laptop and went to TV. Coming back, I realized my system won't boot. Leave along booting, it was not even showing boot menu - the grub menu. Instead it was going to some grub rescue. Grub is a program which shows the OS options when you switch on the system. Yes, it is called grand unified boot loader. But currently it was not able to find the partition. After some googling, I came to know that I should find out the partition in which grub is present using ls command, then insmod something called "normal" and then execute normal command. And it worked, I did get back my boot loader. And hence could boot the system. So I keep thinking about this, many people like me may post the question about grub rescue, but who has the time, inclination and dedication to answer these? But there are. There are plenty of good Sam...
