When I try to reinstall windows XP SP2 at 39 minutes I get an error message stating "The signature for windows XP professional Upgrade is invalid. The error code is 426". I can't load windows anymore because setup keeps restarting. I have 6 hard drives so i loaded windows XP sp2 on one of them. I scanned the other hard drive and found no viruses. I also tried cloning the hard drive and then re running setup thinking it was a hard drive problem but i got the same exact error message.
This is what i have tried but failed
Renamed the catroot2 folder to catold
Deleted the catroot2
Copied the catroot2 and catroot folder from another working windows XP sp2 partition.
Deleted and rebuilt the boot.ini file.
Tried to repair windows XP but i get the same error message
set the boot.ini switch to /MAXMEM=128
If anyone knows how to fix this problem please tell me
