Thanks bunanson. Before announcing my problem, I'd like to inform you all that I am very new to Linux and all these operating as the OS I use most of the times is Windows. However, please scold or flame if you must to get me to understand how to operate this process of booting a 16gb SDHC onto n800. Second, I would like to state that I have succeeded in booting from 2 GB SD card using this website http://thisweekinnuclear.com/KDEonN800.html, on maemo.org (how to easily boot from a mmc). Unfortunately, I struggled a lot because I didn't really understand what they were really talking about with the repository and stuff. And some stuff is missing because I believe they expect people to know it already. Such would be installing becomeroot in order to do sudo gainroot on xterm. Overall, I really didnt really know how I managed to boot from a 2GB SD card, but it was probably luck. I decided to install KDE, but it failed because it did not have sufficient capacity. Now before this time, I had about 1.4 gb on the device to use and around 400mb on the partition. KDE requires 1.5gb, so I decided to find the tarballs and certain files, but with my "newb-self" I wasn't able to find the tarballs or detemine which file is unnecessary to have. I tried to do search and type in tar and stuff like that, but it's not there. However, I began to realize that even with 2gb sd Card, I don't think that is sufficient for me as I want my n800 to have as much as possible because I would like to keep many useful apps to run on n800 and not just KDE. So I decided to purchase a 16gb SDHC ADATA card. After searching around, I have found so many people failing to boot from a 16gb SDHC. I began to be hopeless, but surprisingly, I came across this thread from Milhouse and bunanson and a few other people. I was very excited to see that they are able to boot from the 16gb SDHC.
