i would like to install Windows NT Workstation 4 and Windows 98 on the same machine. i used to know how to do this but i can't remember clearly how i did it... so i am asking for some advice. i have heard that you should always install the oldest OS first, but also that 9x always gets installed before NT. both will be installed on their own primary partitions and i am working with an empty hard drive. so which shall i install first?

Somehwere (over the rainbow - but just where???) I posted here a full how to to do it; one that allows you assorted options too - and covers most bases... Can't find it just now... but these links all cover it in varying degrees; and there is inevitably some duplication in cross-references... And many contributors to the content there... http://www.computing.net/answers/wi... http://www.computing.net/answers/wi... http://www.computing.net/answers/wi... http://www.computing.net/answers/wi... http://www.computing.net/answers/wi... http://www.computing.net/answers/wi... Multiple OS – and can easily be adapted…: http://www.computing.net/answers/wi... Essentially I'd configure the drive: Active Primary: c: = fat16 = 125-150Meg. Extended partition: d: = NT - fat16 - max of 4Gig; can also be ntfs of course... e: = shared data = fat16 -2Gig max. f: = fat32 = '98... Install NT first; make ERD; keep handy and safe. Install '98; run NTrepair routine with ERD you did remember to make... Why the large fat16 Primary? you can install a basic NT there at any time to allow you repair options various for NT main installation if it goes belly up. You can also create an ntfs partition in excess of 4Gig prior to actual set up of main NT installation. '98 fat32 is best at end of drive; but if 98 = fat16... then it can go ahead of NT. Put data in the middle so or at the end; but as '98=fat32 is generally (M$ and others info) best at end of drive where NT is present... put data areas in the between both OS regardless...? Active fat16 primary will have boot/startup files for both OS stored therein.... Do not wipe/reformat/tweak that partition; otherwise no boot to either OS... It can be say 50Meg, but I'd go the 125-150Meg - as drive space is cheap/plentiful these days...? Once dual-boot established and working ok - renew NT ERD; keep safe etc...
