BSOD upgrading from XP Home to XP Pro

[Guest]

Last weekend, I attempted to upgrade my home PC from XP home (SP2) to XP Pro.
Midway into the "installing devices" portion, I got a BSOD about a
BAD_POOL_CALLER.

The hex dump was:

0xC2 (0x7, 0xCD4, 0x340045, 0xE2793DF4) (extra 0's in hex addies removed for
brevity.)

Well, now I can't complete the install, and my PC is in limbo. It boots up
fine, but then goes right back into the "resuming upgrade" function. I can
boot to DOS okay, but attempting to boot to safe mode generates: "You can't
upgrade from safe mode - booting in regular mode" (or words to that effect).

So - I sure need to know how to:

1) Bypass this fault

2) Allow my system to boot into it's old O/S (which I know is still there,
since the upgrade never reached "finalize upgrade".)

But in order to do #2, I need to know the path and file to change/delete.
(The one that tells the PC it's in upgrade-mode.) Any specific help would be
hugely appreciated!

One more thing:

When I access the boot menu, all that shows now is XP Pro, where at an
earlier stage, it showed both XP Pro *AND* XP home. So I need to tell it that
XP Home is one of the options, but also don't know how.

My eperience is based on XP Pro systems.

I guess that you cannot upgrade from am XP Home System which has not got SP2
installed to an XP Pro system which has got SP2.
Try getting back to your original system by booting from the original Home
CD and following the prompts for a repair install. Then if you get your Home
system running OK first install SP2 and subsequently do the upgrade to XP
Pro with SP2.

Actually, I had installed SP2 on Home first, and had "integrated" SP2 into
the XP Pro install (burned a new CD per the instructions for "slipstreaming"
(?) the SP.)

So yeah, I had SP2 to SP2 as the basis of the install.

Dennis,

Well then it does seem that SP2 is the problem so you have got to repair
your Home installation, then upgrade it to Pro and then install SP2 on Pro.
Using the slipstreamed version to upgrade will certainly not work in the XP
Pro environment in my experience.

Don't be discouraged, many users have problems installing SP2 if there is
anything unusual about their existing installation. You have to get the
source installation OK before SP2 can be installed.

BTW make sure you uninstall your antivirus software before you upgrade with
SP2 and reinstall it afterwards

Okay. So I boot from my original XP Home CD, and select REPAIR INSTALLATION,
right? I sure hope it works...

Yes I think that is your only way back. If it does not work I suggest you
make a new installation naming the OS folder name Windows2. Install Home,
Upgrade to Pro, install SP2. Install your applications. I all is running OK
then look in the old Windows folder and see if your data files, e.g.
documents, pictures, spreadsheets are still there in which case you can copy
them in over the newly created data files in your new system.

Hope it works OK. Let us know how you get on.

Okay, thanks! Now, how can I force the PC to install the Home O/S? Remember,
it's "stuck" in the "resuming installation" cycle, and I think I have to
break it out of that before I can attempt to install the original O/S.
