run two Windows 98 OS on same PC

Hi,
Is there a way to run Windows 98 OS on same PC twice. (We’ll use on OS at a time of course!)

Problem is we’ve got Office 2000 & Office XP. Now on Windows 98 only one of these can be installed. Word Templates made in Word 2000 often give problems in Word XP… Like Bold Black Round Bullets turn into Empty Square Bullets OR we cant insert page numbers etc.

The Plan is to have a PC running two Windows 98 OS. One will have Office 2000 (C:\Windows & C:\Program Files) while the other will have Office XP (C:\Win98 & C:\Program Files98). So that win 98 OS are both in different folder as is Program Files. Is it possible ?
