Comment 5 for bug 1266195

Remember I still have the Dell created first partition, then the first Linux extended partition starts at 41.9MB (parted doesn't appear to have options to output in sectors I'm afraid).

Using fdisk it appears the Dell partition (type de) starts at sector 63 and my extended partition starts at 81918 and my first Linux partition starts at 81920.

Note that this is after I got a working install by creating an ext4 /boot partition (which is the partition that starts at 81920).

It is a test machine though, so I could blow it away and test a new install if necessary.
