 Posted: Sat Dec 31, 2005 9:44 pm Post subject: Making Grub boot once into a specific profile? |
 |
|
My goal is to have a button in KDE that, once clicked, will log me out, reboot the system, and choose a specific grub profile to boot into (windows, for games), but only boot directly into that profile once. When I reboot out of Windows, I'd like the normal grub menu to come up, which, naturally, has my Gentoo installation as the default.
How can I do this?
Someone had posted this small script:
| Code: |
!/bin/sh
# a simple script to reboot into windows once without user
# intervention. Assumes that the menu listing corresponding to
# windows at least has "win" in the title. If it doesn't, you can
# change the WINSTRING variable below.
mount /boot
WINSTRING=Windows
GRUBMENU=/boot/grub/menu.lst
let "WINNUM = `grep title $GRUBMENU | grep -in $WINSTRING | cut -d: -f1` - 1"
#echo "num is $WINNUM"
/sbin/grub --device-map=/boot/grub/device.map --batch savedefault --default=$WINNUM --once
quit
/usr/bin/reboot
|
Which looks like it does what I need. Unfortunately, from what I can tell, Grub has changed, and the "--default --once" options to the /sbin/grub line, above, cause errors.
There is probably a simple way to to this, I just don't know what it is! |

| I'd like an answer to this also, cause it would be useful for doing remote kernel updates |

| Lilo can do this. In fact, KDE already has built in support for using Lilo in such a fashion. |

| Yes, I know lilo can do this. I hate to leave Grub just to be able to do this though.... |

info grub
Look into the savedefault command. If you can't figure it out, I'll post a link to a script I use. |
