singleboot

singleboot

[Paul Tarjan]

I've been wanting for quite some time a method to be in linux, and
reboot into windows for just this one time and keep linux as my
default boot. My only solution so far has been to have a boot disk
with one grub.conf with windows as the default and the other grub.conf
on the hard drive to have linux as the default. Then I push in the
disk to go to windows and pop it out to go to linux.

I have a two part questions. Is there something that I can write to
the grub.conf that will be acted upon once, and then removed? And if
not, is anyone opposed to me adding it? Something like a "singleboot =
#" directive that would override default and then be removed after
grub executes it?

Thanks

What about :

default saved

title windows
root ...
makeactive
chainloader +1

title linux
root ...
kernel ...
initrd ...
savedefault
boot

Then you can select windows and it will only boot once in windows (as
long as you don't select it again sometime).

Another solution would be, if your bios can do that, to define disk boot
order as :

windows disk
linux disk

Then if the windows disk is plugged in, it will not even run grub but
directly the windows bootloader. If nothing is plugged in place of the
windows drive, it will just skip and boot grub on the second.

I'm not sure I got your request right :
Do you want to "physically" remove the boot entry so no one can use it
later ?
Do you want it to be 100% automatic (like used as some remote automation) ?
