F10 using Easy BCD with 4 HD partitions

[fluxam]

An attempt to install on a hard drive with partitions NTFS 1:XP64, NTFS 2:Vista32, ext3 (3) / and ext3 (4) /home made it impossible to boot into Vista. I instructed that GRUB go into partition 3. I had Neosmart Neogrub installed, -- a blunder, I now think.
Other distros can be booted by installing GRUB to partition \ or home and then adding a "Neosmart Linux" boot entry using EasyBCD.
I've fixed the PC. I'm ready to try again; how should I install to those two ext3 partitions so I can still boot into the Win OS'es?

Make the 3rd partion a 320MB ext3 for Fedora n (newest first 9 or 10).
Make the 4th partition an extended partition for the rest of the drive.
On the extended partition define a logical partition Linux 83 for / 6-9 GB, an 82 Linux swap 2G, a Linux 83 /home rest of disk.
Install grub boot sector on 3rd partition sda3. (to use the old stuff, otherwise the default grub installs on the disk mbr, point to the Linux /boot. Used add button in the installer or modify grub menu to add other O/S's)

To install another Linux system, leave room on the drive and repeat /boot , /swap, /, /home.
Install grub boot sector on the /boot for that system and then
modify the first grub to link or boot the second.

There can be 15 sdn partitions on a disk.

Fedora's grub is a modified version and old stiff is obsolete.

Thank you very much.
I'm not clear as to whether I should use Neosmart EasyBCD to point to the Fedora GRUB. Or, are you suggesting using the Fedora GRUB as boot manager to start XP64 and Vista?
Setting up EasyBCD has to be done in Vista, and in my abortive first attempt, only Fedora could be booted.
