View Full Version : [ubuntu] Problems with grub2

January 15th, 2010, 08:24 AM

I'm using ubuntu 10.4 on a embedded system ( i need to use already 10.4 because with 9.10 i have the blank screen problem ). Everything working fine except a booting problem with grub2.

Because this system is embedded , the user doesn't do a usual shutdown but just put off the power supply.
After powering up again , its startup normal with detecting a bad shutdown and do a disk check. After fixing bad disk it reboots again.

And now it is waiting in the grub menu until you select a menu point with a keyboard.

I never noticed this with legacy grub , how to change this ?

It sounds like you have more technical knowledge than I do so maybe you can make use of this HowTo I wrote:

Thanks for this clear how-to

I followed it and now i'm back to the old grub.
Everything working as expected again.

Just for anybody reading this. The problem of the OP can be solved very easily without reverting to Legacy Grub:

Open the file 00_header via

gksudo gedit /etc/grub.d/00_header

Look for

if [ \${recordfail} = 1 ]; then
set timeout=-1
set timeout=${GRUB_TIMEOUT}

Change it to

#if [ \${recordfail} = 1 ]; then
# set timeout=-1
set timeout=${GRUB_TIMEOUT}

Save the file and run

sudo update-grub

Now Grub2 will always use the default timeout
