******* RESOLVED ********** Hi I am having problems using Vista with Sony NEC Optiarc SuperMulti (AD-7170A) OEM DVD Burner.(http://www.tigerdirect.com/applicat...451-1000&CMP=EMC-TIGEREMAIL&SRCCODE=WEM1474C). I have built a Intel Core Due desktop as below. I have my HD0 (IDE) with slave jumper setting connected to the slave side of the IDE cable and the DVD burner with Master jumper settings connected to the master side of the IDE cable (all 3 DVD burner I tried). I initially had problems installing when using a OEM DVD Burner - idvd16dd. So I replaced it with Sony DVD burner - retail DRU-840A. The system then ran fine, I could install Vista Home premium, then the Drivers for my graphic card, other drivers for my motherboard IP35-E (DirectX9, audio etc), Norton AV 2007 and update the vista and Norton online. After this, I replaced the DRU-840A with a cheaper OEM Sony NEC AD-7170A to reduce the cost. However, after I installed the new DVD burner, the system will not boot correctly , when Boot from DVD, it gave me an option to repair, which I did, but without success. After a few tries , not it does not even boot from DVD. I changed the boot order in several fashion but no success. I removed my IDE hard drive to load Vista on my second SATA HD, but when I boot from DVD, it goes to 'Verifying DMI pool Data', stay there for like 20 minutes and the errors out 'Couldn't find BootMGR' Case -- ATX Mid-Tower (ULT31795) Motherboards -- IP35-E ATX CPU (Processor) -- Intel core duo 2 E6750 Graphic Cards/Video Cards -- PNY GeForce 7600GS , PCI Express, 512MB DDR Memory -- 2GB (2x1GB) PC26400 DDR2 800Mhz 240-pin DIMMs crucial Software (O/S) -- Vista Home Premium OEM Hard Drive0 -- 200 GB ATA Maxtor L01P200 200GB 7200RPM 8MB Hard Drive1 -- HITACHI Deskstar T7K500 HDT725025VLA380 (0A33423) 250GB 7200 RPM 8MB Cache SATA 3.0Gb/s Hard Drive OEM DVD Writer -- 16 x Writer idvd16dd / Sony NEC AD-7170A / Sony DRU-840A Power Supply -- Coolmax V-500 - 500 W with 120 mm fan fans -- 1 x 120 mm + 2 x 80 mm any suggestions?
