Strange entry in the boot.ini file

  powerless 23:32 11 Oct 2003

Windows XP SP1 and in the boot.ini file....

[boot loader]



[operating systems]

signature(1bfc1bfb)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Home Edition" /fastdetect

What is the "signature(1bfc1bfb)"?

Yesterday i did reformat and reinstall and have only just noticed this.

Also in msconfig when checking the boot paths. XP tells me that:

signature(1bfc1bfb)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Home Edition" /fastdetect

Does not point to a valid operating system and would I like to remove it?

I will not remove it as i may not be able to boot into XP.

Scanned for a virus etc but nothing.

Talking of a virus, Norton AV 2004 has an option to "Load Auto-Protect during system boot" which is different to "Start Auto-Protect when Windows starts up" Could it be a way of checking for a boot virus?

Computer boots and runs ok but what is the "signature(1bfc1bfb)"?

No. As the boot.ini file has always been as above but without "signature(1bfc1bfb)"

The hardware etc settings on XP (for activation) is in the wpa.db file.

"The System BIOS or controller hosting the boot partition on which Windows is installed, does not support INT-13 EXTENSIONS, or has the INT-13 Extensions option disabled, and the partition on which you installed Windows is either larger than ~7.8 gigabytes (GB) in size, or the ending cylinder number for that partition is higher than 1024." I think that it is the one.

I actually deleted a partition so i think that made it add "signature(1bfc1bfb)" when i created another partition.
