Problem with drive letter assignment in dual boot NT/98

Hi,
I have a 20GB hard disk. I created the following partitions:
primary 2GB active FAT16 (C:) having Win 98

Then, I installed NT 4.0 and using partition magic, resized it (the partition created by NT) to 6 GB. At this point, NT exists in primary partition. But, this has no drive letter assignment.

I then, created one extended partition and put a logical FAT32 partition of 11 GB, which automatically got a drive letter assignment of D:

For dual boot, the WinNT considered itself to be D: drive. But, D: drive is now the FAT32 partition. And, NT shows up as E: drive.

I also have a DVD-ROM and a CD-RW drive.

Is there a way I could change the drive letter for NT partition to D: and the FAT32 partition to E:?

As an aside, when I boot using NT, it comes up but then, does not find D:/program files 'cos the NT gets mapped to the E: drive when the system comes up.

Thanks for any ideas and help.
- Nitish

In NT there is a utillity something called diskmanagment, I have a dutch version and here it's called 'schijfbeheer'. Besides partitioning and repartitioning you can also assign drive letters... easy as that.
In 98 it also should be possible to change you drive letters but I can't help you with that...
Good luck and be careful when using 'schijfbeheer' because some false moves could repartition your system...

Hi Nitish, Somthing that may have happened is that you have created two primary partitions. If this is the case drive letter assignment priority goes to the primary partitions then to the extended.

Based on what I read, it looks like you created a first primary partition assigned C: marked as active. Then inadvertantly created an extended that you have NT on(D:). Then when creating the third partition, possibly creating it as a primary. In this case the drive letter that is currently assigned to the extended(D:), got reassigned to the third partition(primary) and issued the extended(NT) the next available drive letter of E:.
I would start by using fdisk off a boot floppy and check the patition information on the hard drive. Depending on what is found there, I would decide on a couple other options. File systems come into play after you've detemined what partitions exsist.
Just a note, NT comes with its own disk utility knon as Disk Administrator. This allows some administration of your hard drive, but in certain situations it is not helpful. I've found it to work well with partitions in use by NT or free space, but using a utility that resides on the HD itself has its draw backs. Something like fdisk, gets things started. Partition Magic I have also found to be handy and harmful, it depends on the situation at hand.
Anyway, I hope that helps, let me know what you find, maybe I can help further.

In NT, just make sure to move the used drive to an non-use letter, then move one to the available letter. One sentence "don't overlap the letter to a letter that is using at the moment". Also restart the computer after each change to make sure you still got it.

I am not sure about the duplicate drive letter assignment, and this could possibly do with some investigation.
However the just a small point that you may not be aware of: NT4 DOES NOT SUPPORT THE FAT32 file sytem. The only file system that all DOS/Win95/Win98/NT4 support is FAT16.

Therefore if you do wish to have a duls boot machine I would suggest you stay with FAT16.

Further NT has a better file system called NTFS, FAT16 can be changed to NTFS later at any time, however this is only supported by NT and once converted to NTFS the file system cannot be reversed unless you reformat

Vinnie, HelperK and Mukesh,
Thanks for your responses. I was able to change the drive letter by going into the disk administrator. Now, Win98 only sees a C: (FAT16) and D:(FAT32). Whereas WINNT sees only C:(FAT16) and D:(NTFS).

HelperK, your reply was right on the dot.

Thank you so much. Have a great new year!
Nitish

Since you have Partition Magic,why not use
Boot Magic?Install Win 98 using FAT32 and use Partition Magic to move it to the back of the drive.Then install NT and leave the FAT 32 partition alone.When installing NT make a small
FAT partition of 200MB, which will be C:and then create another partition of 2048MB which
will be D: and make it NTFS.NT will then install to D:.The FAT partition will be a primary and the NTFS will be an extended.
After NT is installed,install Boot Magic and Partition Magic.Make the rescue disk for Boot
Magic.Afterwards resize your partitions.Boot Magic will install to the FAT on C:.The drive
letters will get reassigned depending on which OS you use.

OK. so I had the same problem as the original poster (Nitish). But when I try to take it one step further, I run into another problem. When I try to partition my extended DOS partition into more than one drive, NT won't boot up and gives me a stop message:
STOP: INACCESSIBLE_BOOT_SECTOR

In other words, I would like to have at least two drives in my extended DOS partition - at least one FAT32 and one FAT16 so I can transfer files btwn Win98 and NT. When I partition and format one FAT32 drive and use the above solution, everything works fine. But when I try to partition a new drive in either FAT32 or FAT16, NT gives me the above stop message when I try to boot up. I even tried making the NTFS drive drive G - thinking the other drives would be D,E,F - but that didn't work. Even tried repairing with ERD, but that didn't work. Does NT limit to only ONE drive in FAT32, i.e., does the above solution (using Disk Administrator) only work with one drive in the extended DOS partition?

Thanks,
dante
