I have the video link, but being the impatient person (i.e. stupid) I am I didn't watch it and landed myself in a mess. As is probably obvious, I don't know what I am doing and am learning the hard way.

The hard drive install is only temporary as I read somewhere that it is easier to do it from the hard drive and I have the from HD remaster FAQ in front of me (also I can go on the web when I am stuck - which is all the time).

The size of the partitions is quite big because I thought that it would not matter if they were a bit bigger than needed as long as they weren't too small ( and also because my ext2 file systems on my attempt on my very small old laptop were read only and someone said that it might be because my drive was small) . I used the code (in root - su) chmod -w /mnt/hda1 to try to make them writeable but I guess I got that wrong. My FAT file and ext3 partitions on this computer are also read only

I do trawl through all the relevant forums regularly but to be honest I don't often get it.
If you are reading this save me from a hideous body under an express train situation and tell me the code for

1 making my FAT file and ext3 partition writeable
2. adding a boot folder/directory to either my ntfs partition or my FAT32. I have tried mkdir /mnt/hda1 (and hda7)/boot.
