I couldn't install win 98se from my disc. In the end I reformated the harddrive and instead of running it from pc, copied over all the CAB files. This worked a treat
Windows 98se is far better than Win98, and as already mentioned, you cannot go backwards. Windows ME is ok until things start to go wrong, then it's a pain. Windows XP can take some getting used to, but it's not too bad. A lot of ppl say that windows 98se is better than ME and XP.
