(The added bonus was that I Ubuntu automatically mounted the HFS+ so I was able to recover a bunch of picture from iPhoto and phone booth)
And none of this would have been possible without UNetbootin.
It is definitely the hero of the day.
So the S10 has a weird partitioning layout. It only uses the first half of the drive (in my case 80GB) for the XP Home (FAT32) partition there are 3-4 other partitions, some more or less hidden for the backup features that I would know about if I had bothered to break the seals on the product documentaiton.
Of course dd|gzip (then back again) on an Atom processer takes forever so there was a lot of downtime. 40 GB images. I think it compressed down to 7GB or so, but to and from an external USB drive. You get the point. Drive imaging is slow, but now I have a dual boot (8.10 and XP Home) S10. This is the 2nd time I installed 8.10 and the long and short of it it is supported pretty well. No more quirks than on other Laptop hardware.
