Thanx for the reply anomie, I had gone through this handbook, but was somewhat confused after reading an example it had, mentioning dual boot (windows & bsd), I haven't done any major changes in partitoning so far, so I have some doubts regarding this....
>Now, out of 10 GB on primary partition (windows C: ), only about 1gb is free. So i need more space on my primary partiton, how to go about it, can i free up part of my extended partiton (the ubuntu part) and extend my primary partiton, is this possible with partiton magic/g parted ( I haven't used these before)
>Or should i format the whole disk and start from scratch?

plz suggest
