Here's a very easy way and undocumented (I think) way to make a Vista boot disk.
1) In Vista, format a floppy disk. Do not make a MS-DOS startup disk.
2) Boot into another OS or WinPE or BartPE (whatever OS gives you access to Vista files).
3) Copy "bootmgr" file from root of Vista to the root of floppy.
4) Create a folder called "Boot" on floppy.
5) Copy "BCD" file from "Boot" folder on floppy. Rest of the files in "Boot" are not necessary.
If you are dual booting, then your "bootmgr" and "BCD" may be in your other OS partition.
Also, if you have a dual-boot system with XP and Vista, you can also boot XP from the floppy. Copy bootmgr, BCD as described above and also add to the root of the floppy ntdetect.com, boot.ini, and ntldr.
Note that bootmgr and BCD reside on the active, primary partition. So if XP is the active partition and is the primary partition, then Vista boot files will be in the XP partition. This occurs when you install Vista from within XP.
Addendum
Note: for the purposes of creating XP-only, Vista-only, or XP/Vista dual-boot floppies as described in http://www.msfn.org/board/index.php?showtopic=95537, you should change your "Startup and Recovery Settings" in Advanced System Properties from within Vista. Save the settings, boot to XP, then copy the modified bcd file to floppy. You must do this each time you change the settings.
Addendum 2:
This boot disk will only work on your system and not some else's system. This is because bcd contains a unique GUID for your Vista installation.
Your suggestion looks great but I have one question:
I have a Laptop with NO floppy drive, only a CD/DVD writer and 4 USB ports. Vista Ultimate 32 bit OS is my only OS.
I just want to flash/update my BIOs and have to do it from the command prompt at boot up as it's a .bat file not an .exe file. Cannot do it from within windows via the command prompt. Just the way this laptop is setup from the Manufacturer.
I'm guessing if I copy the "bootmgr" file from my root dir over to a CD and boot to the CD...it should bring me to a command prompt on start up or do I need the "BCD" file?
What is the "BCD" file? Do I need it?
Thanks

Vista boot disk is very important. There is a feature in Windows Vista where in you can boot your PC thro' USB disk. Get more information on http://www.vistahunt.com/windows-vista-boot-cd.html here. The Vista has a newly built boot loader with two parts. Vista booting is quite fast.
