Vista & Kubuntu 7.04 dual boot problem

[noddy]

Hello there, peoples!

I have a pc with AMD Athlon 64bit dual core, 4GB memory, 2x250GB discs and Vista home premium 64bit. The 2nd hard drive has been deliberately left unused for Linux.
In order to ensure that my Windows was not destroyed by the Linux install, I disconnected the disc drive with windows on it & booted from the ISO dvd. Then I installed Kubuntu to the 'only' disc drive and it works OK, I think!
The problem is the Linux drive is not now visible within windows but is visible in the windows hardware descriptions! No boot option appears for Linux. The only way to start it is disconnect the windows drive!
How do I get a dual boot, please?

Regards, Noddy

Hi and Welcome !

Plug-in both Hard Disks in such a way that Kubuntu boots up by default.
Press Alt+F2 and type this

kdesu kate /boot/grub/menu.lst

Above command will open menu.lst file in kate editor. Put # sign before hiddenmenu line and add this code at the end of file.

title Windows Vista
        rootnoverify (hd1,0)
        map (hd1) (hd0)
        map (hd0) (hd1)
        chainloader +1

Save file and reboot machine. GRUB Menu will appear at startup. Select Windows Vista and check if it boots up.

EDIT:
In case it doesn't work, boot up Kubuntu, open Konsole and execute this

sudo fdisk -l

Post output here.

Thanks, Casper

It still does not work properly.
I edited menu.lst as directed, but now get
'Error 23: Error while parsing number'
when I select the Vista option.
Apologies for delay in replying - it is taking me a while to remember how to use Unix! Its been a good few years since I used it.
I am having a few strange problems now, the windows system time keeps going 1 hour out and shutdown no longer switches off (or is taking a very long time!), I have to use F11 at startup to be able to boot from the second disk to start Linux. I cannot connect to outside world with Linux.

fdisk output is attached.

I can see attached output of fdisk.
