Hello, I have a laptop Lenovo T61 and I cannot boot Windows Vista Business in any mode. After choosing one boot mode, I can see the loading progress bar, but after a while I always get a blue screen with stop code: 0x0000007E This problem started after the following story: - One week ago on the 28/11/2009, while browsing with Firefox I quickly got infected with 'Security Tool' virus and also some other malicious script which would sometimes redirect to ask.com while browsing. - I was able to remove the security tool virus (and other malwares) by booting in safe mode and running Spybot. The computer at this point worked fine, but the problem of redirection to ask.com still persisted. - Meanwhile Vista asked to install new security updates. I accepted to reboot to complete the installation. Before rebooting, Windows was "configuring the update 2 of 3" and I got a blue screen. - Now I am not even able to get to the login screen because when windows is loading and the progress bar is visible, I soon get the usual blue screen with stop code: 0x0000007E My attempt to solving the problem were: 1) booting in any available mode 2) using Vista Recovery DVD "Startup Repair" 3) using Vista Recovery DVD "System Restore" 4) using Vista Recovery DVD "Command prompt" and running chkdsk /r Nothing worked: * I dont have Restore Points nor backups * chkdsk just found just some errors while cheking indexes (stage 2) * "Startup Repair" recognizes that I am unable to boot windows but it says it cannot fix automatically the error. In the report it says something like this: Problem Event Name: StartupRepairV2 .... .... Pleas Help! Thanks.
