@zeeshaan please stop spamming wrong informations. your "fix" has absolutly nothing to do with the problems here reported.
just encountered the same problem on one of my servers. i checked on some of my other servers and noticed that they hadnt installed grub2, they used grub make sure you have installed grub-pc and not the old legacy grub this fixed it for me apt-get install grub-pc grub should be removed and the grub2 package will get installed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/360378 Title: Gave up waiting for root device after upgrade then busybox console -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
