In case you get stuck with this problem:



Normally I boot to menu on IDE and default XP boot menu option is to boot

SATA1. A few months while testing some beta software, I had disconnected 2

SATA drives after doing a drive copy and had just the IDE hooked up.

Yesterday I turned the test box on again and reconnected those drives.

config = 1 IDE and 2 SATA's ( Seagate normally = SATA1 and Maxtor =SATA2)

Default boot to SATA and can't see SATA1. I checked and the power SATA1 had

not been reconnected so I did that. I then booted - menu defaults - starts

XP - get to logon screen and I login. However drive letter assignment is

bad. I realized that the first time I booted SATA since my 'normal drive'

wasn't hooked up, in the BIOS my first boot option for SATA drives is the

Maxtor. Restarted - checked - that WAS the problem. I changed the boot order

so SATA1 is primary boot again and restart. I can login but then get "

Logging Off" right after entering user pwd. .Removed SATA2

Disconnected all but SATA1 and works OK. Same with IDE. But with both

connected, IDE boots but SATA1 just gives " Logging Off" after entering user

pwd. .

..

Today I was going to repair XP ( recovery console). I need to check mail

first and rather than disconnecting the IDE cables, I just disabled in BIOS.

Booted SATA - it saw the IDE - correct drive letters - all better.



=======

if you have SATA and IDE bootable drives and IF you accidentally change boot

order and thereby reassign drive letters for a XP disk, DISABLE the IDE

drive in BIOS and boot SATA. once XP is working, it still sees the IDE

drive, reassigns the "correct drive letters" = fixed.

Made no sense to me - shouldn't DISABLED in BIOS mean 'the drive won't

work'? , but if I toggle enabled/disabled IDE the problem came and went.

With IDE drive disabled, I was able to boot SATA successfully AND IDE drive

was there - with proper drive letters.

I shutdown, rebooted, re-enabled IDE in BIOS and boots either fine now.

Huh? The BIOS will boot using the bootstrap code (first 446 bytes of the

MBR) which is in the first sector in the first non-partitionable track on

the first hard disk that the BIOS finds dependent on the disk boot order

specified in the BIOS. So it sounds like your BIOS finds an IDE disk first

and gets the bootstrap code from that disk. That bootstrap code then reads

the partition table in that same MBR (master boot record) to find which one

is designated as the "active" tagged partition. It then loads the boot

sector from that active partition which then begins loading the OS. Only

then do you get Microsoft's "boot menu" to select which OS to load that is

listed in the boot.ini file (Vista+ changed this a bit but not regarding

what the BIOS and MBR bootstrap will do).



So my guess is that the first detected disk by the BIOS is an IDE device so

the MBR bootstrap from there gets used to load the boot sector for Windows

in the "active" partition on the IDE disk. The "Windows XP" selection in

the boot.ini file points to a partition on a SATA disk where is the rest of

Windows. Although the terminology sounds a bit backwards, you configured

Windows so its "system partition" (used to boot the loader for the OS) is in

a partition on an IDE disk and its "boot partition" is in a partition on a

SATA disk. While most users install Windows where its system and boot

partitions are the same, it is possible to install where they are different

and even on different disks.

Then were was the Windows that you loaded at that time? Previously you made

it look like the system partition for Windows was in a partition on an IDE

drive which loaded the rest of Windows from its boot partition that was on a

SATA drive. If you disconnected the SATA drive, just how would Windows get

loaded? If all you had left was the IDE disk then you must've changed your

Windows installation so the system and boot partitions were both on the IDE

disk (either as the same partition or as two partitions on the same disk).

Because when you only had the IDE disk you had changed your installation so

the boot partition was no longer specified as being on the SATA drive. For

you to boot Windows using the solitary IDE disk meant that *both* the system

and boot partitions for Windows had to be on just that IDE disk.



If you want to abandon the boot partition that you put on the IDE disk, you

will need to edit the boot.ini file so it points at the partition on the

SATA disk where you previously put the boot partition for Windows.
