Help with edit grub.cfg (grub 1.97~beta4)

[redcodefinal]

So i recently tried installed Ubuntu 9.10 hoping i could dual boot with windows 7. My last post had t do with fixing it. I have it sort of fixed but, when I try to boot to my win 7 I get a error:invalid signature. I figured out this is because the only boot option is chainloader +1

I need to edit grub.cfg manually to add in the boot options or else I have to manually type them in every time I want to boot to windows 7. I noticed I have to have permissions from root. how do I login as root to fix my issue...

You don't login as root.

1. ALT+F2

2. gksudo gedit <path/to/filename.ext>

it keeps sending me to home/(username)/boot/grub/ for some reason... Sorry I am a bit of a ubuntu noob.

put a / before boot/grub

so it should read

gksudo gedit /boot/grub/grub.cfg

[redcodefinal]

Still won't let me save... Says it is read-only

Then you're SOL if gk/sudo can't do it, we don't give instructions on how to login as root, it's against forum policy.

If you have installed new grub you do not edit grub.cfg. There are several files that get copied into grub.cfg on every update or your when you make a change you run the update.

All you should have to do to find windows is:
sudo update-grub

This runs the osprober that finds other operating system and updates and changes you make to

gksudo gedit /etc/default/grub

Which is a new file that is like the comment area in old menu.lst.

If prober does not put a correct entry in you can copy your entry to 40_custom, edit it there and then run the update. You can turn off the osprober to prevent duplicate entry in /etc/default/grub with this entry:

GRUB_DISABLE_OS_PROBER="true"

Just wondering then: Why the hell does google/etc. give instructions on editing the grub.cfg and not what you did? It's very frustrating.

OSprober doesn't add the right parameters for windows 7... It only adds chainloader +1. I know this will solve it. I can add them directly when I boot through GRUB but they won't save. So far I am guessing this is the only way to fix this.

I get this every time I try to save

You are trying to save the file on a read-only disk. Please check that you typed the location correctly and try again.
