I need some help and advice please. I've read the article on dual booting in 3d spotlight and read all the posts on this forum and the old one but am still in need of help. I have two hard drives each split into two partitions. Win 98se is installed on C. I would now like to install Win 2000 advanced server on F ( 2nd partition of my 2nd drive) From within Win98 I have started the Win2k installation. It says that I can't upgrade from 98 to 2k which I don't want to do anyway. Next screen gives clean install as the only option - this is fine. I agree to the license agreement. Next screen I choose Advanced and select "I want to choose the partition to install to". I click on OK and it begins to install setup files to my C drive ( it doesn't give me a choice here - it just does it ). After this, PC reboots. I then see a boot menu with 2 options - "Windows" and "Windows 2000 advanced server setup". The 2nd option is already highlighted and from there it launches into Windows 2000 setup. This is a blue screen ( rather than a Windows type screen ) which checks out some things such as hardware configuration. About a minute later installation stops - after about 30 seconds I get a Stop error message "Inaccessible boot device". It asks me to try again but still the same. I've used my virus program - no virus. I've used scandisk, although not the thorough option - no problem. Where do I go from here? Should the setup files have installed to my C drive containing Win98se or should it have asked me about which partition I wanted to use first? Please help.
