[SOLVED] Laptop Debian 6 Restart and Reboot problem.

andrewthomas · 03-10-2011, 07:36 PM

When you boot your computer from a power-off state, you are shown the debian grub2 menu with a spacefun-grub background.

When you select the first entry you boot into your debian-6 install.

The second entry is for debian recovery mode.

The third entry is for your windows recovery partition.

When you select the last entry you should then get another menu enabling you to choose to boot windows or your Ubuntu wubi install.

I don't see anything wrong here.

Could you post the contents of the /etc/default/grub file on your debian install?

I think it may have installed the first grub into the small 100mb partition that Windows 7 calls the loader then switches to the C: where Windows is and gives the graphical choice for grub. Once there I see the 4 choices. Does that explain what I am seeing? Hope so

Scroll down to wins os to boot wins.

Booting into Windows not the problem. The problem seems to be that if I choose restart from Debian it doesn't go through POST it just restarts Debian. I would rather it went through post so I can choose Windows or Ubuntu.

At boot I see grub2. Wubi if I am not mistaken shows up when I select windows then I see Windows or Ubuntu its part of the Windows boot menu - used to be in boot.ini file.

It would help to see this.

Code:

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

GRUB_DEFAULT=saved
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX=""

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_LINUX_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

Here it is.

I would have to think that maybe wubi is allowing the restart to go back to OS instead of computer. Maybe you can check your wubi configuration. I myself would prefer to have 1 bootloader handling job. Having to make a selection from 2 boot menu's would drive me crazy.

If this were the case, it would be happening when using Ubuntu, not when using Debian.

I would reinstall grub-pc from Debian and see if that helps.

I may be mistaken though.

Oh, guys, don't touch grub! The bootloader is not the case here. I've just tried Debian 6 live, install os from it. Live and real installation have the same behavior - command "reboot", also from Gnome menus -- does something (stop gnome, X manager, stop and start some daemons as I can catch on screen), but not the real hardware reboot. I've recall the Win3.11/95 option "reload windows" - windows was reloading, but whole PC was not. I guess, it's some optimizing idea of developers.
For now I'll try to dig into it.

hex_messer · 03-21-2011, 07:09 AM

Ha! in Debian 6 reboot is "RapidReboot", done with kexec. It's really fast reboot of kernel (into running or new). So let's reading...

hex_messer · 03-21-2011, 08:00 AM

So, the described behavior is because of kexec-tools. It's init.d script executed (by design) just before the reboot script, so only the kernel is rebooted.
In first look I can't figure out how to configure kexec to be optional, so for now I've just uninstall package kexec-tools.

Try it out! It's your solution.

hex_messer · 03-21-2011, 10:20 AM

And one more: kexec-tools seems to be installed by default while installing from Debian 6 Live disks. Installation from basic DVD set with two options "Graphical environment" and "basic utilities" does not install kexec-tools.

I have not tried this yet as I have been on vacation all of last week. Will try soon and let you know. However what is kexec-tools and do I need it? Thanks for seeing my original post and pointing to something that sounds like a solution.
