I installed a OEM copy of windows vista ultimate  (not beta) on my machine. Before the install, I was dual booting Windows XP and Fedora Core 6 and they both worked fine. After the install I can boot to Vista and Fedora without problem, but when I select XP from the vista boot menu, the screen just goes black and all hard drive activity stops.

Before the install i had XP on two partitions on drive 0, and fedora on drive 1. Within XP, i formatted the second partition on my drive 0 (D:\) and then booted the Vista DVD. After the vista installation, i used EasyBCD 1.52 to setup the linux boot option (which worked great). Here are the entries reported by EasyBCD:

Entry #1

Name:  Microsoft Windows XP [Professional_SP2]
BCD ID:  {ntldr}
Drive:  D:\
Bootloader Path:  \ntldr
Windows Directory: 

Entry #2

Name:  Microsoft Windows Vista
BCD ID:  {current}
Drive:  C:\
Bootloader Path:  \Windows\system32\winload.exe
Windows Directory:  \Windows

Entry #3

Name:  Fedora Core 6 [Zod]
BCD ID:  {91df954f-b243-11db-950d-000129fbad38}
Drive:  D:\
Bootloader Path:  \NST\nst_grub.mbr
Windows Directory: 

I have no idea why XP wont start after the vista install. My only guess is that ntldr was corrupted during the install, however the file is present on the d: drive within vista. I had noticed that the install cleaned up my boot.ini on the d: drive. The wierd thing is that Vista calls disk(0)parition(1) d: and disk(0)partition(2) c: - which is the opposite of XP. I also tried adding an entry from EasyBCD that was identical to entry #1 above only the bootloader path was c:\ . When trying that i got a screen that said:

Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:

1. Insert your windows installation disc and restart your computer.
2. Choose your language settings, and then click 'Next'
3. Click 'Repair your computer'

If you do not have this disc, contact your system administrator or computer administrator for assistance.

File: \ntldr

Status: 0xc000000f

Info: The selected entry could not be loaded because the application is missing or corrupt

Anyway, any help here would be really appreciated! I would love to be able to multiboot xp, vista and fedora. Thanks for replies!

I have sinced fixed my problem. I used the XP cd to format my hard drive (into 2 partitions) and reinstall XP on partition 1. After installing XP, I booted from the Vista CD and installed on the other partition. Everything then worked fine. I also used VistaBootPro to backup my BCD file. Within XP, I used's bootpart to create an entry for fedora in XP's boot.ini. After a reboot, Vista's bootloader added the Fedora entry from XP's boot.ini to the Vista bootloader, so now I can load all three OSes from the Vista Bootloader! Ka-ching!

If XP's bootloader is gone (you mean it seems to skip it when you boot XP?). Boot to XP, and right click on My Computer, then Advanced (i think). Find Startup and Enviroment Variables, and reset the time to show the OS Selection screen to 30 (or appropriate time). I am not sure but I think Vista's bootloader somehow changes this.

Another thing you can try is when you select "Previously installed OS" from the vista bootloader, immeadiately tap F8, and you should be able to bring up the XP boot options screen.

Tip: Install VistaBootPRO and rename Previously installed OS to something better!

LMK if this helps at all, I'll help all I can but I am a total vista-noob! :)
