Do you apply any updates or upgrade any packages in the time between the system booting fine and it then failing?

I get an error message saying "Gave up waiting for root device" and then drops to the (initramfs) prompt. When this problem first occurred, simply typing "exit" at the prompt would resume the boot process. However, now I have to wait for almost 90 seconds (I'm guessing) before the "exit" command is able to resume boot process. I have noticed that the time during which the system is unable to resume the boot up process, the /dev/disk/ folder does not exist. In my earlier attempts at diagnosing the problem I have tried: 1. Reinstalling the grub 2. Identifying disks using the UUID as well as sda/sdb in the Grub 3. Updating the Linux kernel (previous install) On the bright side, once the system boots up it runs fine without a glitch. This is an old laptop with an unserviceable DVD drive plugged in that is disabled in the BIOS. I hope that you folks can help me find a solution for this annoying problem. Thanks!
