today my company buyed hp proliant dl380 g8. i configure RAID 10 with my disks. i puts installation DVD with windows server 2008 enterprise sp2, but the server doesn’t boot from dvd. the dvd is bootable. i used provisioning but i can’t choose dvd, i receive option for network, usb, ftp. in bios first boot device is cd room but it’s not work. why? can i install windows manual without hp tools and how?
