I setup a new ubuntu quantal system and edited /etc/default/grub as follows:
# If you change this file, run update-grub afterwards to update
# /boot/grub/grub.cfg.
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX=""
# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with
Every time update-grub is run all hard drives are scanned. Each drives that is in standby state will spin up to go idle. This is a waste of energy. We use update-grub version 1.98:
# update-grub -v
grub-mkconfig (GRUB) 1.98+20100804-14+squeeze1
Regression
There is a GRUB_DISABLE_OS_PROBER=true option in the /etc/default/grub file. But that seems to only work from version 2 and up.
Q1. In /boot/grub/grub there are many references to a UUID.
Where does grub get this reference? I would like to change the source and then run update-grub.
I prefer not to edit the grub file manually because then when I do run update-grub the UUID will come back.
Q2.
After upgrade to 12.04 my GRUP was broken. I thought that a single problem so I booted from Ubuntu CD, mounted my Ubuntu disk, then grub-install, restarted PC and everything was fine again. But I've noticed that GRUB crashed after every GRUB packages update. I did today 12.10 upgrade and it happen again. Is that GRUB issue or maybe is something wrong with my hardware?
Any ideas for getting around this stumbling block, anyone? I'm testing quantal, and running several other Ubuntu installs, some on the main HD (sda) and others on a USB external drive (sdb). Since the update to grub2I've been having increasing problems with grub, not accessing some installs, etc.
Two (Vaio) laptops, Vista/Quantal on one, Windows 7/Quantal on the other, Quantal on both fully updated as of a few minutes ago. Both have Windows recovery partitions on sda1 and boot into Windows itself from sda2. (7 has the usual separate small boot partition on sda2).
Apart from Quantal, the grub menu on the Vista machine only has an entry for the recovery partition, not for Vista itself.
My grub menu went through rather extensive changes after the last update. It started booting to my old 12.04 entry by default. Where this gets confusing is that there is no longer a 12.10 entry in grub.cfg.
I installed and tried the grub-cfg as mentioned in How do I change the grub boot order?
Hi folks,
Have just come back from hols to find large upgrade for QQ and after it was complete update grub gives the following error.
Code:
sudo update-grubGRUB >= 2.00 has been unpacked but not yet configured.
grub-mkconfig will not work until the upgrade is complete.
It should run later as part of configuring the new GRUB packages.
Can't find anything that tels me how to fix it.
I just installed a fresh Ubuntu (12.04 I think, currently running 10.04) onto a new partition (formatted with btrfs) but the end of the installation gave me a Grub could not be installed error. So I went about adding it manually using this guide:
http://linuxnorth.wordpress.com/2011...ub2-revisited/
which involves editing the grub.cfg via the 40_custom file and running update-grub.
