Grub Doesn't Show boot Windows 7 as option

[ducis]

hey,
I just installed mint. I created a 64gb partition manually and have successfully installed mint but.....
in grub there isn't an option to boot my windows partition even though I can browse it in mint.

sorry for being a noob,
ducis

Try in the terminal doing

Code: Select all

sudo update-grub

for some reason it isn't always detected in the first place.

Reboot and see if that works. If not, can you post the output of the boot info script? http://sourceforge.net/projects/bootinfoscript/

[ducis]

sure,
how do I use the boot info script?

[beefstu]

did

Code: Select all

sudo update-grub

not work?

ok download the file and save it. It should save it in your downloads folder. In a terminal

Code: Select all

cd ~/Downloads

then

Code: Select all

./boot_info_script055.sh

That should create a results.txt in your downloads folder which you just need to copy the contents and put them here

This is a pain in the rear for new Linux users like us

See my thread above.

[ducis]

terminal replies when I enter ./boot_info_script055.sh

bash: ./boot_info_script055.sh: Permission denied

[beefstu]

woops sorry should be as root

Code: Select all

sudo ./boot_info_script055.sh

[ducis]

all i get now is
sudo: ./boot_info_script055.sh: command not found

(sadface)

[beefstu]

still need to be in the same dir so

Code: Select all

cd ~/Downloads

then

Code: Select all

sudo ./boot_info_script055.sh

sorry i didnt make that clear!

[ducis]

Thanks for being so helpful,
but i still get the same thing

did I need to specify I was going for a dual boot when i installed? I just made a swap and file system partition.

In order to allow the OS to run a script, you must first make it executeable. This is an easy to forget step, but it would account for the error you are receiving. Try this:

Code: Select all

cd ~/Downloads
chmod +x boot_info_script055.sh
./boot_info_script055.sh

Good Luck! Grub can be more than a bit stubborn at times.

IMO check out the link I posted. I was having the exact same problem as you... and now I dont.

[beefstu]

cebalrai may be right, you might want to try adding Windows 7 to your menu.lst. You presumably upgraded from Mint 7?

Cebalrai, could you post what you added to menu.lst, been a while since I dealt with grub1?

[ducis]

i added

Code: Select all

title Windows 7
root (hd0,1)
makeactive
chainloader +1 

to the end of the menu.lst, and got windows 7 as a boot option in grub, but when i select it I get "Invalid Device Requested".

How do I know what root hd# my windows 7 partition is?
