I have noticed a number of folk seem to have had problems somehow doing
upgrades. I have always done a clean install from CD and not had any. Now having
got a new PC i will probably do a USB install.

I actually did this exercise for the first time a couple of weeks ago. First
time i was a little unsure like yourself. I have a 500G disk with 4G RAM. For
swap you need twice your RAM but over 2G stick with the amount of RAM... is what
i read. But the install disk actually does it for you and answers that question.
So how much space to allocate? I used to have two hard disks so put the system
on one and used the second for storage - ideal way to my mind. I'm actually a
xubuntu user - which uses <6G. I chose 100G for / and the rest for /home. Just
seemed a safe place to start. Now i think 50G would have been a better choice as
i've got 87G unused. I'm not going to put that much on to use up that amount of
In summary on the install ubuntu have got everything thought out [excellent OS!]
you only have to chose the size for / and it will do the rest unless you want to
allow for a FAT32 partition or another distribution. Personally i think the two
drives is the safer route... but my smaller drives are pata not sata [think i'd
have to look into a conversion cable maybe when i get the time].
