So while talking always nice about Linux (today as well on devrant), my laptop wouldn't boot. I realised the battery was drained out as i had put it to sleep.

Now when i switch it on the light just blinked and nothing happened. After sometime when the battery was a bit charged and i had tried to hard reset the laptop, still wouldn't boot.

An hour later it was stuck at the bios screen asking me what I'd like to do- boot normally or repair. Anything I clicked it'll reboot and get back to that screen.

I realised after sometime that it was the RAM that was being the pain. So got a bootable usb to check the RAM. Post that it booted without new installation. Phew...
