I am performing a test in which I hard-reboot a machine with Ubuntu during its boot sequence (just before login prompt appears).
After the reboot, GRUB's menu shows up with no timeout (not its rescue-mode, but the usual menu), as opposed to before reboot where GRUB had a timeout and started to boot Ubuntu.
I am using a fresh installation of Ubuntu 12.04 LTS Server for my tests.
Although it is a nice feature for recovery, I would like GRUB to continue the "usual boot" sequence with the default timeout, instead of the "fail-safe" mode where it waits for input, even if previous boot failed.
How is it possible?
