UPDATE the os is ubuntu server 8.10... I've tried setting up grub from knopix but on setup command it reboots the pc... Also I've entered safe mode, using the cd option "boot from first disk" because it's the only way it boots, and started grub, did the root and setup followed by a reboot to watch progress and nothing... on the process i found something strange the boot drive was hd4,1 insted of hd0,1 that i get from grub before inserting cd... how to go arround this? <div class="gmail_quote">---------- Forwarded message ---------- From: Bruno Pinto <<a href="mailto:bpbroas@gmail.com">bpbroas@gmail.com</a>> Date: Sat, Mar 28, 2009 at 4:36 PM Subject: ubuntu server intrepid does not boot To: <a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a> Hi all. Sorry about my english and great thanks in advanced. I'm building a data server it as : - amd Phenom 2 2.3 GHZ - 2X 2GB ddr2 800 Kingston - 4 sata2 500GB seagate - two sets of raid 1 - mobo msi k9a2gm v3 - 40 GB ide for system It works fine if drives are set to ide on mobo bios or with only ide connected. If i set raid on mobo the systems hangs after grub displaying only a blinking cursor... But if i run the install cd and choose "boot from first disk drive" it boots normally. I've being for hours trying to work this out and nothing, already tried gsd and other and still nothing, what to do? Thanks </div>
