"Operation system not found" when installing 13.04
Solution 1
Well, running fdisk
again, to write a fresh partition table after having wiped it along with the MBR, seems to have done the trick. I am now able to boot the live DVD/USB key and get started on Ubuntu 13.04 installation.
Thanks for the suggestions!
Solution 2
You need to set your SATA mode to AHCI instead of RAID in you BIOS. Also make sure you remove the RAID meta-data:
sudo dmraid -E -r /dev/sda
sudo dmraid -E -r /dev/sdb
Now reinstall Ubuntu, and you should be fine.
Keep in mind that any other operating system won't work anymore after this.

I am attempting to install 13.04 on a Dell XPS 15 (L502X), onto an Intel SSD. I have run
shred
to wipe the contents of the SSD, so I should be starting from a clean slate, and my objective is for Ubuntu to use the entire drive. Note, though, that I had an older Ubuntu installation on this SSD prior to runningshred
.However, from both a amd64 DVD and an amd64 boot USB key (created using Startup Disk Creator from the downloaded ISO), I get "Operation system not found" when I attempt to boot. If I try booting from something else (e.g., an old SysRescue Linux mini-CD), it boots fine, so the issue is not that the L502X cannot boot from external media.
I even double-checked that the MBR on the SSD was wiped by using
dd
. Still no luck.Any suggestions?
(and to those editing the title, no this is not a typo in my question)
Thanks!
UPDATE: Replacing the SSD with another hard drive (one with Windows 7 on it) allows the USB key to boot. Hence, the problem is with the SSD. The SSD itself seems fine -- SysRescue Linux sees it. However, there's something on it that is preventing the Ubuntu 13.04 live DVD/USB from booting, for some reason.

CommonsWare over 10 years@psusi: I cannot run the script, as I do not have a non-Ubuntu bootable Linux environment handy that is capable of accessing either the Internet or a thumb drive from which I can load the script in question.

ubfan1 over 10 yearsDid you md5sum check the downloaded iso? See help.ubuntu.com/community/HowToMD5SUM Check the number against the listing in the link for your release listed at releases.ubuntu.com under the MD5SUMS link.

md5sum
checks out fine, but thanks!

CommonsWare over 10 yearsMy Dell XPS L502X notebook does not have a RAID option -- it was already set to ACHI. Running
dmraid -E -r /dev/sda
reportsNo RAID disks and with names: "/dev/sda"
, which fits. Thanks, though! -
