Tattooing HP’s

After updating Bios on my HP Pavillion XE I can no longer use old recovery disks that came with computer — screen comes up and says Sorry unable to use this disk Disk is for A HP computer only…
How can I fix this? or is there a fix — I Changed HDD one that came with it was a Maxtor 40 gig I changed it over to a WD 80 and the Maxtor is a slave drive
