I'm trying to verify whether PartitionMagic 8.01 will automatically "fix"
the boot.ini file and the partition boot sector where it resides during the
rearrangement of disk partitions.

Specifically, say I have an XP primary, active partition as the third
partition on my HDD. The first two partitions are logical partitions.
Initially, the boot.ini file would point to the third partition.

If I now delete the first two partitions so as to make the XP partition the
first partition, will PartitionMagic automatically rewrite the boot.ini file
to make it point to the first partition so as to make subsequent boot-ups
possible?

Thanks,

I wouldn't have thought so. You are in fact delting the boot.ini file when
you delete the first 2 partitions, so where will the boot.ini file be?
Deleted as well, I say.
You will have to create another boot.ini file on the same partition you want
to boot from.



I appear to be mis-understanding something. I thought the boot.ini file
resided in the "partition boot sector" which, in the original setup, would
have been located in the third partition (active, primary).

If not where does it reside? Are the "partition boot sector (PBS)", boot.ini
file always located at a specific location on the HDD - I thought this was
true only of the MBR, which in turn pointed to the PBS (which is located at an
arbitrary location). Is my understanding incorrect - it would appear so.



Sounds comprehensively mangled to me.

The boot.ini file is a file in a particular partition, it wont even fit in a
PBS.

More likely something works out which is the bootable partition
on a particular physical drive and something works out where the
boot.ini is from that and reads it from the appropriate partition.

Dont know the answer to your original question, I'd personally
ghost the entire physical drive so you can recover gracefully
of PM didnt handle the deletion of the logical drives properly.
Cant see why it shouldnt.


I guess this gets down to understanding the boot process. My current
state of confusion is:

1. The MBR is read from a fixed location on the HDD.

2. The code in the MBR eventually points to a bootable partition (there
may be more than one, but I guess only one is active at a time) and
jumps to the PBS of the active partition.

3. Code in the PBS then starts to load the OS, eventually reading the
boot.ini file located in that partition's root directory (as you indicated)

4. Now, if the boot.ini file contains lines for mutiple OS's, a menu
appears. A selection here would then cause a jump to the approriate
partition for the loading of the selected OS.

My head hurts. Does the above seem correct? If not, what does happen?

Thanks,
Harvey
