800b0100 error code XP error instalation?

[Unregistered]

Hi,

I have a XP Professional copy, P4 Prescott at 2.8 Ghz with Sp1. I downloaded and instaled.
I installed also the SP2 for two weeks.
I got the MSblast window ("you computer will be shout down ...etc) and i erased all
svchost.exe registry entry. My system crashed and i entered my XP professional SP1 included
and i tried to reinstall the OS.
Here is the error messages:

" Setup failed to install the product catalogs. This is a fatal error. Error code is 426"
" The signature of Windows XP SP1 Professional is invalid. The error code is 800b0100"

I tried all the trick described in here and no result. The system make the same infinite loop.
The CD-ROm is the first boot option also i tried the "catroot2 to catold" trick.
I forgot to mention that i do not want to loose the OS, because all my registered programs and
all my work is there. Also i have the legit XP SP1 copy with license.

Please help!

Please someone help.

Same problem, too!
I think it is because I disabled some services and/or changed some security settings.
Have you done something like this?

It's working!
BTW, I had to wait ~30 minutes at "39 minutes left", but then setup resumed (and finished).

Hi!

What have you done exactly that the setup resumes? What have you changed?

Greetings!

You could always reformat and preform a celan install, it adds 30 minutes, but without it you have xtra junk on your computer that you must reinstall and programs you cant reinstall (lost the disk) then you have to manually delete. Just use a free reformatter, and then install.

I have encountered the same problem. please advise exactly what you did or did not do while you waited the 1/2 hour for the restart.

It would greatly be appreciated.

Desperate!

I had the same problem today, and after finding nothing from searching the web, i found a soulution to the problem myself. The link from microsoft didn't work for me. I had a situatuon where the motherboard was fried by a lightning stirike, so it had to be replaced. Offcourse, i had to repair my windows installation, but i didn't know which version of XP pro was installed, and neither did the owner. I tried repairing with a cd that had SP2 integrated, and ran into this problem. So, booted from SP1 cd, and restarted the repair process, and the problem was gone. So, it was just a different service pack that caused the problem in my case. Hope this helps

i think its because of the change of operating system or service pack the logs are saved on your hard drive soi you need to format
