Tri-Booting, Windows 7 & XP

[Inconsequential]

Right setup is as follows:

Intel SSD: OS X
500Gb HD, three partitions:
1. 150Gb Windows 7 x64
2. 100Gb Windows XP x32
3. Macintosh HD 5 (rest)

Now, both systems are installed but currently it doesn't give me an option to boot from either Windows 7 or XP, it just goes straight to Windows 7.

How do I get a boot selection screen up?

Cheers.

Hold Option on startup.

Hold Option on startup.

Not what I mean.

On the option screen "OS X" And "Windows" comes up.

Selecting "windows" make it immediately boot into Windows 7.

I need to know how to find out how to add W7 and XP separately to the Option Boot Screen. OR.
Find out how to sort out the MBR/Bootmgr so that I get the Windows Boot Option screen.

Do the two Windows OSs show up separately in System Preferences -> Startup Disk?

Neither of them do!

You may want to ask crazy frog how it all worked in the end. https://forums.macrumors.com/threads/920673/

Install refit

I had a smilar problem. Solved this by installing refit from the snow leopard os.

I did the following.
1. Partition to three separate partitions 1st as hfs+ and others as fat
2. Install snow leopard on 1st partition
3. Install windows 7 on 2nd partition reformatting as ntfs during install.
4. In windows 7 go to "disk management" and set 3rd partition to active.
5. Install windows xp on 3rd partition and reformat as ntfs(quick)
6. Now when you boot a refit boot screen should show up.

Note if refit doesn't show the other partitions just reinstall it in snow leopard

btw email me if you have any problems, but google it first.
