Hi,

I have two disks in mt computer and several partitions on
each of them. I have two win200k installed. One personal
use, another one professional use with complete different
stuff.

One of the disks is devoted to just data. The other disk
contains two bootable partitions on win2k and two data
partitions.

From the personal partition, I upgraded the data disk (no
OS) to dinamic. Fine, but the profesional partition will
not recognize the volume/disk anymore. You can actually
see and work them ( the disk letters are there) but the
disk manager will say that there is something wrong and
will not show anything.

I then upgraded the OSs disk to dinamic. It shutdown down
OK and on startup I got a blue screen.

After that, none of the disks will show up on the
professional partition. Still, it boots and you have
letters to acces the disks.

On the personal partition, the data disk will show as
dinamic and OK. The OSs disk will not show up. However,
both OS partitions are accesible and thwo data partitions
on the OSs disk were lost..... really bad... I had to
recover manually..... a pain.

Do you have any reported problems upgrading basic disks to
dinamic disks ???, especially if it is the OS partition ??

Thanks.

I don't know of a common cause of problems in converting basic to
dynamic. In that process a 42 is written to the partition table and the
LDM database is created. I have never tested in a duel boot but it would
not be ideal in that configuration. Question, why are you converting to
dynamic? Dynamic has no advantage over basic and should only be used if
you are doing software RAID (where it is required).

If it is a OS partition it cannot be downgraded... Here is
the fix though... The probelm is that the Pro OS does not
know that the disk is Dynamic and does no know how to read
it. Givce this a try to reset the pointer in the OS that
will not load / cannot be seen.

This is for a rebuild but you get the idea.

Dynamic Disk Operating System Re-Install Directions
Step 1 - Create Boot Disks
To create a set of Setup boot disks for Windows 2000, run
the Makeboot.exe tool from the Bootdisk folder on the
Windows 2000 CD-ROM:
1. Insert the Windows 2000 CD-ROM in the CD-ROM
drive.
2. Click Start , and then click Run .
3. In the Open box, type drive :\bootdisk\makeboot
a: , where drive is the letter of your CD-ROM drive, and
then press ENTER.
NOTES
.. You do not have to be running Windows 2000 to
create the Setup Boot disks. A directory called \Bootdisk
resides in the root of the Windows 2000 Setup CD. This
directory contains two utilities capable of generating the
4 Setup Boot floppies. If you are booted into Windows 9x
you will need to run the 32-bit version of this utility
called makebt32.exe. If you are in DOS, or booted with a
Windows 98 Startup Floppy that has access to the CDROM,
you can use the 16-bit version called makeboot.exe.
.. Disks created from the Windows 2000 Professional
CD cannot be used with Windows 2000 Server; the reverse
combination also does not work.
.. Before deciding that a computer must be started
from a CD or floppy disks, you should first try starting
in safe mode on that computer.
.. After starting a disabled computer from floppy
disks, you can then use the Recovery Console or the
Emergency Repair Disk (if you have prepared one).

Step 2 - After Boot Disk Set is Created - Proceed with the
following.
Create a copy of the Disk 1 of the Windows Setup disk by
using the diskcopy command. To do this:
o Click Start , and then click Shut Down .
o Click Restart the computer in MS-DOS mode , and
then click Yes .
o At a command prompt, type the following command,
where <a> is the drive that contains the Windows Setup
disk and <b> is the drive that contains the blank floppy
disk to which you want to become the Windows bootable
disk:
diskcopy a : b :
2. On the Floppy disk Delete Setupldr.bin
3. Copy both the Ntdetect.com and Ntldr files from
the I386 folder on the Windows CD-ROM to the new floppy
disk.
4. Rename the Ntldr file to Setupldr.bin.
5. Create a Boot.ini file.

The following sample Boot.ini file provides an example for
a single partition SCSI drive with Windows installed in
the Winnt folder; however, the exact value in the
[operating systems] section depends on the configuration
of the Windows computer that you want to boot:
CUT AND PASTE THIS SECTION INTO A FILE CALLED BOOT.INI
SCSI - Instruction
Leave ALL parameters alone except Partition On Compaq
Servers built with the Diags partition CHANGE Partition(1)
to Partition (2)
[boot loader]
timeout=30
Default= scsi(0)disk(0)rdisk(0)partition(1)\winnt

[operating systems]
scsi(0)disk(0)rdisk(0)partition(1)\winnt="Windows NT"
IDE - Instruction
Leave ALL parameters alone except Partition On Compaq
Servers built with the Diags partition CHANGE Partition(1)
to Partition (2)
[boot loader]
timeout=30
Default= multi(0)disk(0)rdisk(0)partition(1)\winnt

[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\winnt="Windows NT"
NOTES -
If your computer boots from an IDE, EIDE, or ESDI hard
disk, replace scsi(0) with multi(0). If you are running
Windows NT 3.5 or Windows NT 3.51 and your computer boots
from the first or second SCSI drive, then you can also
replace scsi(0) with multi(0).

If you are using scsi(x) in the Boot.ini file, copy the
correct device driver for the SCSI controller that is in
use on the computer, and then rename it to Ntbootdd.sys.
If you are using multi(x) in the Boot.ini file, you do not
need to do this.
6. Start your computer by using the bootable disk,
and then log on to Windows
7. Let setup complete as normal *** LEAVE DISK IN
UNTIL INSALLATION IN COMPLETE
Step 3 - Once system is Up and operational
1. Insert the Windows 2000 CDROM
2. Browse to the System \ Tools folder Run the
Setup.exe to install the System Tools
3. Go to Start -> Programs -> Support Tools -> Tools
4. *** THE FOLLOWING IS A VERY EXACT PROCESS DO NOT
RUSH AND FOLLOW TO THE LETTER
5. Start Dskprobe.exe.
6. On the Drives menu, click Physical Drive , and
then double-click the physical drive that represents the
system/boot drive.
7. Click to clear the Read Only check box, click Set
Active , and then click OK .
8. On the Sectors menu, click Read using the default
settings.
9. On the Drives menu, click Volume Information , and
then write down the following values:
o Sectors / Track
o Tracks / Cylinder

10. On the View menu, click Partition Table .
11. Locate the active partition **(the Boot Indicator
field lists "SYSTEM")** by double-clicking each partition
table index entry. Note the Relative Sector number for the
active (SYSTEM) partition.
12. Click the Go button next to the Relative Sector
number for the active partition.
13. Based on the file system type (FAT or NTFS), click
FAT Boot Sector or NTFS Boot Sector on the View menu. This
displays the BPB information for editing.
14. Change the Sectors Per Track entry from 1 to equal
the Sectors / Track value that you noted in step 5.
15. Change the Heads entry from 1 to equal the
Tracks / Cylinder value that you noted in step.
16. After you verify that both BPB entries equal the
correct values, click Write on the Sectors menu.
17. Verify that you are writing to the same sector
that you recorded for the Relative Sectors setting, and
then click Write It .
18. Quit the Dskprobe.exe tool and restart the
computer without the boot floppy disk.
