Recently I installed Fedora Core in a Virtual Machine in Vista Computer. Because is on a virtual Machine i don't get the full power of the computer.
Got some Issues with login and x, but I resolved with help of Tink(moderator) and reading other post here.

Now I want to do a Dual boot. I know many people have already ask about dual boot and maybe many post about it. But the last time I tried end with boot problem (grub error), none operating system boot. No Vista, No Fedora. Tried reinstalling Fedora a second time to be sure i added Vista in Grub boot loader, with no success.
So I reinstalled Vista again.

So now I wanna know if theres a safe way to do it. Any Linux distribution with Vista.

Vista already installed

AMD Semprom 3100+
768 MB ram
nVidia GeForce 6100
2 hard drives (wanna use 1 for linux)

Try these instructions here: http://apcmag.com/node/5162/

I have set up a dual-boot numerous times, there is not much hard about it as long as you have the right grub syntax

I wanna thanks Linuxquestions.org, and all people who helped setup Linux on my computer

This time i used Ubuntu to install. Easy, Fast, no need to configure the boot loader for vista. All was automatic. Recognize all hardware and gave a solution for my nVidia card.

the website Nexus gave above is excellent for dual boots

Thanks

The sad side of the story is every dual boot with Linux is safe.

It is the duty of every Linux installer to check every hard disk partition for a boot loader and automatically include it as a booting choice if one is found. All Dos, Windows, BSD and Solaris systems place their boot loaders in the root partitions and so will be included by Linux installer to multi-boot, usually without the user lifting a finger.

If a user installs a Linux with Windows already inside it he/she has to sabotage the installation in order to avoid ending up with a dual boot.

Why sad? Surely it's a good thing GNU/Linux is op/sys friendly.

IMHO- the only *really* safe way is to use 2 (or more) HD's and physically unplug the existing OS drive, install on the other driver, then either muck with grub to chainload the original, or use the BIOS boot order choice to boot.

I find it easier to just single boot Linux (though I do worry sometimes when distro-shopping that I might hose my stable install ).

The way I did it, while Pata disk device names were in use, was to partition each hard disk in 63 partitions, wrote a Grub menu.lst to boot all of the empty partitions and then installed the Linux to fill up the disk gradually. Each partition became bootable as soon as I installed a system inside. With a Sata I could still put 44 Linux inside, although the standard way is to have no more than 15 partitions.

What a awful waste to use one HD to install a Linux with a average footprint no bigger than 3.5Gb?
