I have a refurbished Dell PowerEdge R200 using a SAS 6 RAID controller that I am attempting to install Ubuntu Server 10.04.3 LTS x64 on. I have a RAID 1 setup that I am installing to. Well the install of Ubuntu Server x64 went through with no errors, but when I rebooted it went to a (initramfs) prompt complaining that it gave up waiting for the root device.


As soon as it shows that prompt, I can type enter and it continues booting to the logon prompt. Iíve done a good amount of research at this point and cannot find anything concrete that will fix this. One thing I found is for Grub and it says to add rootdelay=90 to /boot/grub/menu.lst but Grub2 doesnít have that. I have also tried editing /etc/default/grub to uncomment GRUB_DISABLE_LINUX_UUID=true so that grub stops using the UUID. It appears to me that itís just timing out before the boot path is fully detected. Does anyone have any ideas?

After You See the message
"Press <Ctrl-E> for bmc setup within 5 sec......"

Hold Down Shift

Then do the following



Some netbook users have had success by placing "rootdelay=90" at the end of the "linux" line when they boot.

At the Grub menu, highlight the entry you want, press "e" to edit the menuentry.
Find the "linux" line. It probably ends with "quiet splash".
Add rootdelay=90 to the end of that line.
Press CTRL-x to boot.

If it works, edit /etc/default/grub (gksu gedit /etc/default/grub) and add rootdelay=90 to this line:
Quote:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash rootdelay=90"
Then update grub:
Code:
sudo update-grub
You may be able to reduce the value of rootdelay.


boot into the server / login in
update grub as per the post..
