Can anyone help me decide the ARC path I need for my PC?
I have an HP Vectra XU 6/200, with the following drives:
IDE Primary Master = 4GB, Program Files, etc. ("C:")
IDE Primary Slave = 2GB, Data, Backups, etc. ("D:")
IDE Secondary Master = CD-ROM ("F:")
IDE Secondary Slave = None
SCSI ID 0: LUN 0, = 2GB, Windows 2000 System ("E:")

If I set my BIOS to boot from the SCSI, then OK.
In this case, the SCSI is drive 80h
However, I need to be able to boot from the IDE Primary Master.
On the E: drive, I have NTLDR, NTDETECT.COM, and BOOT.INI
On the C: drive, I have NTLDR, NTDETECT.COM, and BOOT.INI

Boot.ini looks like this:

[boot loader]
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional on SCSI" /fastdetect

When I set the BIOS to boot from the IDE interface, I get "cannot find %systemroot%\WINNT\SYSTEM32\ntoskrnl32." (or something along those lines)
In this case, the SCSI is Drive 82h

I have tried many and various combinations of multi(?) and rdisk(?), but cannot find the right, working combination.
I've tried the Microsoft article "Microsoft Windows XP - Reviewing and Correcting Boot.ini Settings on x86-based Systems", but I still can't figure out where I'm going wrong.

Re: ARC Paths in BOOT.INI

Yes, I've read that, partially understood it, but still can't find the right solution.

NTBOOTDD.SYS doesn't exist anywhere on my system, so i can't use the scsi(0) method in place of the multi(0) method, if that is what is needed.

Re: ARC Paths in BOOT.INI

OK,problem solved.
By running the Recovery Console, I was able to use the MAP ARC command.
This showed me that the correct path is:

Got there in the end!
