Hello Armin,
Setup repair cannot find the \boot folder with the BCD file nor the \window
that contain Windows Vista.
Does the \boot folder exist and is there a BCD file in that folder? Can
you see that folder while inside of Repair if you open a CMD prompt?
It may be possible the drivers for volume are not present so the disk isn't
seen
How does a previous version like XP know to load bootmgr.exe instead of it's
own ntldr.exe?
These are not exe files. It's bootmgr and NTDLR no extension. The pointer
to those files in the bootcode on hard drive. Those two files have to
start prior to the boot.ini loading.
So the code in the master boot record ( MBR) points to load either NTLDR or
Bootmgr.
NTLDR in turn would then load the boot.ini.
Bootmgr would load the BCD file, which if had a entry to Windows XP would
include a pointer to load NTLDR which then would load the copy of boot.ini.
What do I need to modify in XP's current files such as boot.ini to make this
work?
This can't happen, NTLDR has no way of passing control to Bootmgr, has no
knowledge of bootmgr and contains functionality above what bootmgr..
Bootmgr has the ability to point to NTLDR and thus work,
The change has to come from loading bootmgr properly at boot time and
having a correct BCD file present.
Thanks,
Darrell Gorter[MSFT]
