Thank you for your responses. I have tried hda7 and there is no difference to the booting response. I will go away and have a read where suggested but perhaps you will be good enough to give a little more guidance. 1. Where do the NFS filesystems that it is looking for come from. Is it a part of the kernel config? 2. When I generated the kernel config I thought that I had enabled sata drives. Are there any sign posts in the config compilation that a numpty can recognise? 3. Will the system, as it is presently created, tolerate me going back to reinstall 8.3 (hence reconfigure) the kernel? Lastly a few details of the machine. -- mbo Gigabyte GA-M61SME-s2`Nvidia6100/405 chipset which are believed to contain MCP61 sata controller. Two 80G Maxtor HDDs. Two ide CD/DVD drives. AMD 64 dual core - virtually silent! Finally I apologise for my hamfisted way of replying to the lists any hints and tips here will also be appreciated.
