I have partitioned my drive as follows: Disk 1 1)C: Primary DOS Partition (FAT 16) 2)Extended DOS Partition E: Logical DOS Partition (FAT 32) F: Logical DOS Partition (Fat 16) Disk 2 1)D: Primary DOS Partition (FAT 16) I installed Windows 98 on the E: drive, then wished to install Win NT on the F drive. However, When I install it and Win NT asks to be rebooted (just after copying all the files over) I get an error message on boot (Boot record signature AA55 not found (5806 found)) Basically it won't let me boot. Windows 98 still boots fine however. Here is a copy of my BOOT.INI [boot loader] timeout=5 default=C:\ [operating systems] multi(0)disk(0)rdisk(0)partition(3)\WINNT="Windows NT Workstation Version 4.00" multi(0)disk(0)rdisk(0)partition(3)\WINNT="Windows NT Workstation Version 4.00 [VGA mode]" /basevideo /sos C:\="Microsoft Windows 98" Thanks in advance for any help, Michel

Your boot.ini shows that W98 is installed on the C partition, not E as you stated. Did you use a utility to create the E parition as FAT32? NT isn't going to like that either. Normally, you would install W98 on the C partition and NT on another, with all partitions being FAT16. Of course you can convert any of the partitions to NTFS, but then when you boot to W98, you won't be able to see that partition.

NT doesn't like having a FAT32 partition in front of it... You have the FAT16 system (active primary) partition bit correct... (Basic requirement for dual/multi-boot NT/'9x/etc.) If you can, using PM4x/5x, convert the FAT32 back to FAT16, and then you should be able to install NT OK to F: (Remember the 2Gig limit for FAT16.) If you still want E: as FAT32 then convert it to FAT32 'after' NT has been installed... Ideally, put '98 into F as FAT16 or FAT32, and install NT into E. Usually it's better to have the c: system area as a boot/start-up partition only, with just the NT/'9x (& even DOS) boot/start-up files there; and maybe the i386 Folder (and possibly the '9x Folder too). Then install NT/'9x from there... C:\i386\winnt /b /x /s:c:\i386 (and press Enter) is the command to install NT from the C: system area. Usually a faster/smoother/less problematic install... If you're willing to start over... Make the C: system area around 250Meg, copy the i386 and '98 Folders to it (use a DOS boot-disk with CDROM support or the '98 boot-disk which includes CDROM support...), and then install them from there... Partition the Extended area of HD-1 for NT and '98 areas. NT can be NTFS later if you wish, '98 can be FAT32 later if you wish. It's not really necessary to have huge partitions for the system files in either case; 2Gig is more than enough, whilst data etc. can be usefully larger if need be... As W2KStud remarks, your boot.ini points to C: as being the '98 location, not E: . This being so, once you have resolved the FAT32 issue as outlined above, you 'can' leave '98 installed in C: (FAT16) and install NT into either E: or F: - without re-installing '98... This is a popular route to go, but it's far better/wiser to have the C: system for the boot/start-up files (and maybe the i386 etc.) only - as outlined above - and both the actual OS's in separate areas... If you do leave '98 installed in C: then the NT boot/start-up files will co-exist there with the '98 files; and you will still have a dual-boot... http://www.computing.net/windowsnt/wwwboard/forum/3279.html has put together an interesting aproach to having '98 (FAT32)and NT together - and with '98 before (FAT32)before the NT area... You could also install NT onto HD-2-and this may allow the FAT32 logical-drive to remain as is.... I'd partition HD-2 into a not too large primary (around 1 or 2Gig max) and install NT there; use the remainder HD-2 for data etc... You can have NT (system area - the actual OS itself) as NTFS but it's usually a case of over-kill in domestic situations; use NTFS for data etc - if you want to practice 'permissions etc.'; NTFS is hidden to DOS/'9x etc...; FAT32 is hidden to NT/DOS/'95a - without the use of suitable utils (after installation)

This is a know problem when installing NT on to a logical drive you have to manually edit the MBR(boot sector) to make this config work.using an disk editor.
