I am using Ubuntu 11.10. An hour ago I had my laptop Sony Vaio VPCEB1S1E running. I saw there are updates to install and I installed them. I turned off the laptop and now when I turn it on it loads until BusyBox v1.18.4 appears.
I've seen suggestions for solving this on askubuntu. I booted Puppy Linux from USB and repaired the partition where the Ubuntu is installed. I rebooted but it did not help.
I saw other suggestions like writing "exit" at the BusyBox prompt. This didn't help either.
I love the Ubuntu OS, but these days I get problems like this while booting. The last times I could repair it with GParted, but then it wasn't a problem with BusyBox, it was some other error, like "cannot boot /".
The same problem had occurred on Ubuntu 10.10 and there I had repaired it with GParted.
