Not Booting from DVD-R/W

[bkgzb]

Hi All, I have LG DVD-R/W and P-IV (HP motherboard) system. When I boot from CD-ROM from setup. My DVD-R/W is not booting in HP motherboard system but show everything in my computer->DVD Drive. I have tried many bootable CD to boot but not succeed. When I used this DVD-R/W to another system it boot quickly and also when I used another CD-ROM to P-IV HP Machine it boots. So problem is that LG DVD-R/W is not booting with P-IV HP machine. So What I do to boot LG DVD-R/W with P-IV (HP motherboard) system?

Check your mobo model number and update the BIOS from the respective site also change your IDE Cable(If your DVD writer is not SATA) and see the jumper settings too if your HDD and DVD-RW is on a single cable ,then change the DVD-RW jumper to centre,also I recommend you to use the separate IDE cables as there will be two slots of IDE on your MB
I hope it helps
(please post your PC's full specification if problem doesn't solve,as HP systems always have chipset motherboards)
