@dubya : i think its not a faulty iso ... because i've tried 7000 which came up with the same error... but i got that iso from the microsoft site... also i been reading around... formattin with the win 7 happens too quickly ... so this guy reformated the partition in Vista... and it fixed the error... tryin that... also another guy removed his ram because they were bad... and he only used the good ones.... thats another theory ... gonna try that if the formattin thing doesn't fix it... and btw... get ur iso on a different comp.... and use a bitorrent program and force recheck the iso ... just to make sure... these are none of my ideas... only stuff i've found lookin around.... oh what dvd type you using.. i'm using DVD+R
@angryman: i tried the boot from USB but same... error... i'm thinkin its either the disk or ISo....
EDIT: actually when put the iso on a other comp .... and force checked it... it was only at 93 % so .... i guess it was a faulty iso.... but not sure... gonna check it soon...hopefully it works...
EDIT#2: k ... its not ISo... gonna try doin it from inside Windows Xp
EDIT#3: tryin to run in xp didn't work.... gave me different error... i just ran memtest86 and found out that 3 of my ram slots are damaged... one is extremely damaged... so i took out rams on the bad slots... and tryin to install with 1 ram slot... post back soon on my comp hopefully
EDIT#4: YES IT WORKS......

..... i just had to take out the ram on the bad slots.... now it installed completely... ram was the problem ... thx everyone
