I have got a newly built system with following specs Intel Pentium E5300 2.6GHz, 2MB L2 Cache,800MHz FSB P5kpl-AM/PS Motherboard http://in.asus.com/products.aspx?modelmenu=2&model=2507&l1=3&l2=11&l3=563&l4=0 2GB DDR2-800 Transcend Samsung 22x SATA DVD Drive http://www.cdfreaks.com/hardware/product/94539-Samsung-SH-S223B.html Seagate 320GB HDD (SATA 3.0 GBps) http://www.seagate.com/ww/v/index.jsp?vgnextoid=e7c048e03b758110VgnVCM100000f5ee0a0aRCRD The board has 4 sata connectors(SATA1,SATA2,SATA3,SATA4). I have connected the DVD drive on SATA1 and the HDD drive on SATA2. The BIOS options for IDE/SATA storage devices are currently as ATA/IDE Configuration: Enhanced (options are Enhanced/Compatible/DIsabled) Legacy IDE Channels : SATA (Options are PATA,SATA and Primary PATA + SATA) Also i have set the boot priority to boot windows XP from the dvd drive. When i boot up, i am getting this message "Reboot and select proper boot device OR insert boot media in selected boot devices and press a key" I have tried changing the settings to Comaptible mode and PATA/SATA/Primary PATA + SATA. But all of them fail to boot the Windows XP SP2 boot disk. The disk is in good condition and has been used many times before for installation. I am not able to find out the solution to this problem. Please help me solve this problem.
