800b0100 error code XP error instalation?

Hi,

I have a XP Professional copy, P4 Prescott at 2.8 Ghz with Sp*. 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 SP* 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 SP* Professional is invalid. The error code is 800b0*00"

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 SP* copy with license.

Please help!

well you might try to boot of a CD with linux OS on it and see what you can change from there

Thanks for your reply.

I do not know what to change. I just want my OS back, still infected with welchia. It was innofensive.

Please someone help.

Thanks in advance

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 ~*0 minutes at "** 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 *0 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 */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 mother***rd 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 SP* 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

Blacksheep, Dodo05* has been waiting a year and a half for that answer. ;)
