Smile How to get OS choice at boot?

Hi folks, I am a complete & total NEWBIE here. So please be gentle.
Okay, I have an 80Gb SATA drive with Win XP Pro.
I have a 120Gb IDE drive with Ubuntu mounted.
I know that it is supposed to be able to see both and ask which OS I
want to use, but it does not do that.

I probably goofed when I installed Ubuntu because I disconnected the SATA
drive when I loaded Ubuntu because I did not want to load it on the SATA
drive and I did not want to compromise my Windows installation yet.

So, now that I have that fouled up, can anyone advise me as to how to get
the boot system to see both drives and give me the option to choose my OS?

By the way, I now go into the bios each time I want to change OS's.
Thanks in advance.

The simplest option would be to reinstall Ubuntu on the IDE drive but with the SATA drive also plugged in (you should not get confused at the formatting stage because there will already be a Ubuntu install on the SATA one). That way the installation will proceed as normal, but when GRUB (the boot loader) is installed on the MBR, Ubuntu will add both OSes to the menu.lst file (therefore allowing you to choose which OS you want at boot).

But, if you really don't want to do this, PM me and I'll help you along - you'll have to edit a few files though.

Don't worry to much about messing up windows--it is easy to restore the windows boot using the rescue disk.
This said, you have several options:
make a boot floppy or install grub to the drive 1 mbr--all using grub from within Ubuntu.
Re-install and let it put grub in the drvie 1 mbr
Re-install and let it put grub on a floppy
