I'm running into the infamous "Windows could not update the computer's
boot configuration" error while trying to upgrade my Win XP (Pro SP2
OEM) installation to Vista Business (OEM upgrade version)

* I have checked the UpperFilters entry which still reads PartMgr.

* The compatibility check lists these problems:

Avira AntiVir
ATI Catalyst Control Center
Intel(R) Network Configuration Services
Visual Studio .NET 2003
Windows Messenger 5.1

* In setupact.log it says:

* boot.ini looks like this:

[boot loader]
timeout=2
default=multi(0)disk(0)rdisk(1)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Microsoft Windows XP
Professional" /noexecute=optin /fastdetect
C:\CMDCONS\BOOTSECT.DAT="Microsoft Windows Recovery Console" /cmdcons

* System is a Gigabyte 8KNXP P4 2.8, 1GB, with one IDE drive that
holds a 1.6GB boot partition and one SATA drive that holds a 76GB
system partition

Where to go from here?
 
Well since nobody responded I had to solve it myself. I don't know
which step fixed it, but here goes:

- Downloaded EasyBCD and ran it which copied the Vista MBR
- Deleted everything on startup partition except for ntldr, ntdetect &
boot.ini
- Ran diskcheck & defrag

After this procedure Vista was finally able to complete the upgrade.
