Whilst we were waiting for the MSI Wind U100 to come I did some homework and planning by doing some searches of the MsiWind.net wiki and Ubuntu forums and found several items which were of interest.
I found that the drive was likely to already be partitioned into three primary partitions with a 4 Gbyte FAT32 partiion for system restore information, a 40 Gbyte partition for Windows and the remainder of 75 Gbytes being a NTFS partition which was not used. I planned to delete the big NTFS partition and make an extended partition to hold a FAT32 data partition, a Swap partition and two EXT3 partitions for the root file system and a separate /home partition.
There were several forum articles covering Wifi and it became clear that there are now several possible Wifi cards but the most likely one was one I used for drivers was a RTL8187SE WLAN card and I found precompiled drivers at http://boskastrona.ovh.org/index_en.html
The next step was to make a bootable USB stick to install Ubuntu Hardy Heron 8.04.1 and I used
Unetbootin which seems to be the perfect way to install Ubuntu on a machine without a CD. You can either download to the machine and install or you can create a LiveUSB. I created a LiveUSB of Hardy heron and tried it on the only machine which I have capable of booting from a USB stick and it behaved just the same. It looks as if it should be able to create a LiveUSB from an ISO of a LiveCD of other programs such as disk partitioners but I have not tried it yet. In fact I created two LiveUSBs because I made on for the partition editor Gparted as well.
