It's got to the time where I need to do this and I have done it numerous times in the past but this time I am having problems.

Last week bought two new 500gb harddrives and replaced my existing 300gb slave. Formatted and partitioned this and all was okay.

Today I have removed the 300gb master and installed, formatted and partitioned the new 500gb hd with PM8.

I have set the primary partition as active and all the others are logical which is asthe old hd was partitioned.

I have been geting a disk boot failure error on trying to boot from the CDROM with the XP installation disk. Having originaly had the bios set incorrectly I have now rechecked it and ensured the boot order is set to CDROM, HD-0 and the floppy.

I have ensured that the primary hd has been detected, detection is set to to Auto and Access Mode to LBA following the Seagate instructions. I have now also disconnected the secondary drive to exclude that from the picture until I get into the primary drive.

I have also reset the jumper on the new primary to Master having disconnected the secondary drive.

I am at a loss to know what is wrong. Could anyone give me any ideas?
