I have created a partition of MS-DOS FAT on my Mac, then created a Windows 7 Install Disk on my Flash Drive.

When I try to boot using the Install Disk via rEFIt. It just says no bootable disk found.

Why would OS X display a message like that if I used Bootcamp to create the Windows 7 Install Disk?

Have you selected the USB flash drive as boot-disk? – Michiel Sep 25 '12 at 12:24
Yes I did. Could not work installing Windows 7 to my Mac through a USB. Just couldn't detect it. So I resorted to using a DVD installer with UDF format. I will try using the contents of the DVD though to create a USB installer and get back to this post should I find any success. – jeraldov Sep 26 '12 at 3:15
It could be an issue with the USB drive. Switching drives solved a similar problem for me: apple.stackexchange.com/questions/75619/… – recklesscoder Apr 12 at 1:34

Are you sure the iso you started with was bootable ? some upgrade dvds are not bootable (tho most SHOULD be)

While rEFit rocks (all my macs have it) sometimes it just wont see a bootable usb, and sometimes it will see two bootable partitions on them ...

Try to boot with option key and see if osx bootloader recognizes it as bootable. If it also doesn't recognize it, go back to OSX and re-create the boot drive preferably on a different (brand) pendrive.
