Vista - System crashed during install

Was installing service pack 2 and system crashed now can not even get back to my old vista.

Seems to be loading and then I get:

!!oxc 0190005!! 9293/45274 (registry\machine\schema\wcm.//microsoft-...)

Then it freezes. I let it stay here for 18 hours and nothing. Tried to boot with my old vista windows disk and can not get a fix or get back to loading anything. Latest error said windows can not fix problem. Frequant black screen of death after bios or it goes to above point and stops.

Any help would be appreciated.

I think your system have trouble with unload Schema hive - it is only temporary hive and after restart system never use it.Download MEPIS Bypassing Log-in Passwords to Access Folders on Drive
burn,boot it and navigate to folder C:\Windows\System32\config ->in this folder find SCHEMA file and rename to SCHEMA.OLD ,next run system normally.

I couldn't find schema in that location but there is a schema dir in the windows dir. Should I rename that dir?

Thanks

No!Otherwise you will never log to system.Show (or type) contents in this folder.Isn't any file like SCHEMA.DAT,SETUP?
This folder content registry files:
main registry files:

BCD-Template
Components
DEFAULT
SAM
SECURITY
SOFTWARE
SYSTEM

there are also protocols from using these files by system like SAM.LOG and likely...of course don't touch these files.Are there any files with completly different name?

follow the instruction specified in method three in this link. U Your problem will be solved.
