good evening, I have a toshiba 225cds and it has windows 98 curently installed on it. I wish to install a older version of windows on, but I have no flopy drive, neither an atachment. I have entered the bios and the boot PRIORITY said fdd>cd-rom>hdd. I wish to clean the hardrive, but will I be bale to use the cd-rom if i do? it said cd-rom in th ebios but I am not to shure about it. Any help would be appreciated.You are asking for trouble here.  Not necessarily a bad thing, but what you're attempting to achieve isn't easy.  Earlier versions of Windows WILL NOT recognise your CD in DOS mode WITHOUT the appropriate driver and MSCDEX installed.  So if I were you, I wouldn't format the hard drive; I'd just delete the Windows installation, and retain a folder that contains the CDROM stuff.  (Alternatively, if you can boot from CDROM, you could boot from a Win98 CD, and intercept it after it has loaded the drivers.  WOrks in theory, but I haven't tried it.)

Your bigger problem however is going to be drivers for Windows.  Before you attempt this, please satisfy yourself that the drivers for your essential hardware are available for whatever version of Windows you're planning to install.

If it all goes horribly WRONG, you WILL have a recovery path of sorts, provided you can boot from a CD.I am not good with drivers in the past, should i slpit the hdd and put the drivers there?I don't have much EXPERIANCE in your problem, but whatever you do, make sure any harddrive partitions can be READ by your "new" operating system. Eg. FAT. I'm not sure if some older Windows can recognise FAT32.hm... the computer has not been converted to what the screen is tellign me...I have wonderful new! I decided to reformat and my assumtion was corect... I did not need a boot disk. The bios had cd drive together so it was not deleted. Thank you all for such help.
