Fedora 10 x86_64 fresh installation on dual-boot - change boot settings

[Cypress]

I'm totally new to Linux. I've read something here and there. Got a fresh installation of Fedora 10 x86_64 on my HP dv7-1070el notebook with previously installed Vista Ultimate 64bit. I have 2 HDDs. The OS are installed on different hard-disks.
The problem: I've chosen to put the boot loader on the first sector [...] on the second HDD (/sdb5) where Fedora is installed, not on MBR /sda1 where is Vista. Now, when I reboot, it goes straight to Vista and I expected to be asked for a boot choice. What I want is to start using Fedora and to be able to choose which OS I want to use when I start my notebook.
I'm not sure I made myself clear since I'm not too familiar with all terms so please correct me so I can learn . This is what I remember from installation. Everything else went great, no installation problems.

If there's no way to get the dialog of which OS I want to boot, tell me the command for booting Vista when GRUB starts.

Reinstall the boot loader and choose to install it on the mbr of the first disk.

I finally managed it using EasyBCD software and it got what I wanted. Now I'm searching for what I have to do next...I suppose kernel loading and so on...
