GRUB freezes after timeout


Dear All,

I have setup my linux Ubuntu system to automatically boot. Off late, I have detected a small problem that I am unable to understand. My GRUB is set to boot into the default OS after a timeout of 10 secs. Yet, during the reboot, the system stalls at GRUB expecting a user to press the return key, even after the countdown of 10 secs has completed. Any ideas why such behavior is persisting??

Does the selected menuentry boot after you press the Enter key to boot? What version of Ubuntu?

It does boot after keying in the return key. I have deployed the system in external environments where it is expected to function continuously, untethered. I am using Ubuntu 9.10.

As far as I recall, Ubuntu Karmic (9.10) installed GRUB 1.97~Beta4 by default. The grub.conf file is used only by GRUB-legacy (<=0.97).

Santosh, please try this. In /boot/grub there is a grubenv file. Delete it:
Code:
sudo rm /boot/grub/grubenv
If there was a previous boot failure prior to this problem, the recordfail var is set in the grubenv file. The recordfail is an Ubuntu mod to GRUB. On every boot, it looks at the recordfail var, and if its set, it disables automatic boot from the GRUB menu.

I know no other way of unsetting the recordfail var. On the next boot, a new grubenv file will be generated without the recordfail env set.
