Have you configured any raid disk controllers in the bios first? This is a very common question - servers with RAID controllers need to set up with your chosen disk configuration first - when they're happy they will announce their effective device to the OS where the usual partitioning and md-raid, lvm etc can take place.

1: Comfirm your boot menu settings 2: Comfirm your BIOS settings (CD/DVD is active) 3: Verify your download (md5sum / sha1sum). 4: Try the DVD in another system 5: Burn and try another disk 6: Try another boot option / medium: flash, PXE/kickstart, etc.
If you're provisioning a datacenter or multiple systems, I'd jump straight to #6 myself.

does that system have some form of PERC raid controller? you need to go into the PERC Bios (or use Dell's utility disk and the raid configuratator) and define whatever level of hardware raid you want, creating logical volumes that your OS will see as 'disks'.

Thanks very much to all, now I have understood.. anyway it's a perc s300.. I see I can make a virtual disk read-only... very interesting.. well .. to have a /boot partition read-only is a non-sense... thanks to all again... someone has told "google is your friend" .. ..but I say "I prefer human friend".. :-)

Hi,
afaik the Perc S100 and S300 is a software-based raid and only supported on Windows. This is even stated in Dell's server configurator.

1. make sure you are able to see two /dev/sdx 2. create /dev/mdx with them : man mdadm 3. Go home and have a nice sleep
Alternative: What?
