I'm trying to install 10.04.2 on a Dell machine with no current OS. I finally found the thread that said to use the alternate installer if you have a RAID: so i'm using ubuntu-10.04.2-alternate-i386.iso, burned using Roxio on my (different) windows box.
I go through the early installer steps ok, get to partitioning, choose guided resize (potential tangent: first time this modified partitions #6 and #7, second time it was just "use entire disk"). Then "installing base system", then a dialog that says:
Please insert the disk labeled "Ubuntu 10.04.2 LTS _Lucid Lynx_ - release i386 (20110211.d) in '/cdrom/' and press enter
Well, the disk is already in the drive, and the installer has previously claimed it's reading from /cdrom. Reinserting it doesn't change anything. My only choices are <Continue> or <Go Back>, both of which display the same message. So i can't get past this, or escape, or do anything other than power down.
Looking at the disk on my Win machine, it appears to be labeled "Ubuntu 10.04.2 L" (can't tell if that's truncated or not).
Does the installer really demand a certain label on the disc to succeed?? Any suggestions for how to successfully install in this situation?
Update: just to be sure, i checked the md5sum, and it's correct.
