HELP!!!!
I cannot figure this out for the life of me.
Western Digital Hard Drive, 320gig, Cable Selected Primary=Windows XP=HDD-0
Western Digital Hard Drive, 320gig, Cable Selected Secondary=Windows Vista=HDD-1
BIOS Boot Order=HDD-0 and then HDD-1, then CD ROM
I cannot figure out how to get the "prompt" to select my operating system.
If I right click my computer under either Operating System then click Advanced and then Settings under Startup/Recovery it only gives me the option to select the current Operating System.
I"ve tried holding down the F2 button or the F11 button but neither worked.
So far I'm only able to switch by going into the BIOS each time that I want to do this.
My only option left is to edit the Boot.ini file but I'm not sure how to write it
Can anyone think of anything else in regards to:
2 Hard Drives
2 Different Operating Systems
and getting that prompt each time the computer reboots?
Please,
Thanks

Which Operating systems are installed and which drives are they on...
Ideally, you are suppost to install the oldest operating system first. If the newest OS is Win2k or XP it would have/should have created a boot menu.

Heres the brain puzzler (thought I mentioned earlier but maybe not)
HDD-0=Windows XP=Main Boot=Primary Master (think I have it set as Cable Select)
HDD-1=Windows Vista=Secondar=Primary Slave (think I have it set as Cable Select)
So yeah my BIOS reads:
HDD-0
HDD-1
CD ROM
In order for it to boot to Vista I'm having to set it to:
HDD-1
HDD-1
CD ROM
And in order for it to boot back to Win XP
HDD-0
HDD-1
CD ROM
I get no Menu either way

Oh. You did mention it. I'm just blind...
Was XP installed etc when you install Vista?
I haven't actually studied all of the following but have a good feeling it should help:
Windows Vista introduces a new boot loader architecture; a new firmware-independent boot configuration and storage system called Boot Configuration Data (BCD); and a new boot option editing tool, BCDEdit (BCDEdit.exe). These components are designed to load Windows more quickly and more securely.
The traditional Windows NT boot loader, Ntldr, is replaced by Windows Boot Manager (Bootmgr.exe) and a set of system-specific boot loaders. In the new configuration, Windows Boot Manager is generic and unaware of the specific requirements for each operating system, and each system-specific boot loader is optimized for the system that it loads.
Where is the boot.ini?
On BIOS-based computers that are running only Windows Vista, the Boot.ini text file is gone (not hidden) and any remnants of it on interim beta test builds are ignored. On computers with both earlier versions of Windows and with Windows Vista, the Boot.ini file remains to support the older versions but it does not affect booting in Windows Vista.
On EFI-based computers that are running Windows Vista, boot options are still stored in NVRAM. However, in Windows Vista you use BCDEdit to edit boot options on an EFI-based computer just as you would on a BIOS-based computer, instead of accessing NVRAM directly by using Windows APIs or specialized tools such as NvrBoot.
Windows Vista also includes new BCD classes that are supported by the WMI provider and enable you to edit BCD programmatically. For information about BCD classes, see the end of this tip.
Introduction
The Bcdedit.exe command-line tool can be used to add, delete and edit entries in the BCD store which contains objects. Each object is identified by a GUID (Globally Unique Identifier). Every drive or partition on the system will have its own GUID and could be {legacy} (to describe a drive or partition on which a pre-Windows Vista operating system), {default} (to describe the drive or partition containing the current default operating system), or {current} (to describe the current drive or partition one is booted to), or for example {c34b751a-ff09-11d9-9e6e-0030482375e7} (to describe another drive or partition on which an operating system has been installed).
Bcdedit.exe is located in the \Windows\System32 directory of the Windows Vista partition and can be accessed only from the Command Prompt which is found on the Windows Vista start menu at Start>All Programs>Accessories. Then right click on the dos prompt and hit "Run as Administrator". Use basic dos commands like Cd.. (to go back a directory) and "cd windows" (to go foward to the windows directory from the current directory), once you have navigated to the C:/windows/system32 folder enter "bcdedit" in the command prompt.
BCDEDIT Commands
bcdedit /? Shows all commands one is able to use
bcdedit.exe /? CREATESTORE Shows detailed information for the command CREATESTORE or any other command available in bcdedit as shown when running bcdedit /? followed by the particular command more information is required for.
bcdedit or bcdedit /enum all Shows the current structure of your boot configuration data.
The GUID tags {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} of all Windows installations present on your computer will be displayed.
Create a Backup
It is strongly recommended that one creates a backup of the BCD store before making any changes to it.
bcdedit /export "D:\BCD Backup\Bcd Backup" Creates a backup to a pre-created folder, in this case “BCD Backup” on drive D:
bcdedit /import "D:\BCD Backup\Bcd Backup" Restores the backup previously created
Making Changes to the Boot Configuration Data
bcdedit /set {legacy} Description “Windows XP Professional SP2” Changes the text description of the “Legacy” OS line in the boot menu. The quotation marks must be included in the command
bcdedit /set {current} description "Windows Vista Build 5270 x86" Changes the text of the boot menu line for the Vista or non-Vista installation one is currently booted to, from the default "Microsoft Windows" or other description to that shown in the quotation marks
bcdedit /set {5189b25c-5558-4bf2-bca4-289b11bd29e2} description “Windows Vista Build 5270 x64” Changes the text of the boot menu line for any other Vista installation. One must use the GUID for that particular installation as shown when one runs the bcdedit or bcdedit /enum all command
bcdedit /default {current} Sets the current Windows installation one is booted to as the default Windows boot OS
bcdedit /default {5189b25c-5558-4bf2-bca4-289b11bd29e2} Sets the referenced Windows OS as the {default} Windows boot OS
bcdedit /default {legacy} Sets the legacy (Windows XP) OS as {default} boot item
bcdedit /displayorder Sets the display order of boot menu items for example:
bcdedit.exe /displayorder {legacy} {current}
bcdedit /timeout 15 Changes the default 30 second time-out of the boot menu to 15 seconds or any other value inserted.
Correcting changes to the Partition/Disk structure
Where a partition or a hard drive has been added or removed and has caused the partition/disk structure to change, this can be corrected by running these commands in the order shown:
X:\>X:\boot\fixntfs.exe -lh -all (Where X: is the drive/partition on which the folder "boot" is to be found)
bcdedit /set {5189b25c-5558-4bf2-bca4-289b11bd29e2} device partition=X: Changes boot partition of the OS whose GUID is indicated. (Where X: is new drive/partition required). Must be used together with the osdevice command below
bcdedit /set {5189b25c-5558-4bf2-bca4-289b11bd29e2} osdevice partition=X: Changes boot partition of the OS whose GUID is indicated. (Where X: is new drive/partition required). Must be used together with the device command above

so is it better to edit the Boot file in Vista or in XP; cause I cant seem to get the bcdedit.exe to come up in Vista.
If XP is better, what do I need to add to get that prompt under boot.ini file.
Thanks
