Unable to boot - Safe Mode stops after crcdisk.sys

I have this exact same problem.  It started with a virus I still have.  I can't connect to the Internet when I start normally.  Norton has been altered to where I can't get to it.  I started in "Safe Mode" and ran recommended programs to get the virus.  Nothing has worked and I can't start in "Safe Mode".  The Windows repair to is working as I type.  I am currently using the repair tool in the "Safe Mode" options menu.  OK.  That didn't work.  I also followed the suggestions in the first reply.

Any ideas?

same issue Vista 64bit stopped blue screen and majority of app freezes by

changing disk controller from SATA to IDE in bios

removing MSE and putting back on other anti-virus along with turning Windows Defender back on

turn off Aero features for Windows

Scandsk will not repair errors found on second drive, second drive runs fine via USB-SATA adapter just not through actual HD controller on motherboard

Cannot get into SAFE MODE because of crcdisk.sys lock up  

Defrag will not run on computer 

Solution imho DUMP VISTA IT'S ****!! We should all get free copies of 7 or even go backwards to XP

Too many things that go buggy in Vista to fix all of them, OS is shoddy programming.

If anyone else has NEW advice (as you can see most posters here and on other sites have tried all the RESTORE, VIRUS CHECK, CHECK DISK, ERROR REPAIRS etc etc. We don't need someone to keep repeating what we have already tried dozens of times. Please pose NEW advice, besides DUMP VISTA.

Thank You , (a very frustrated Vista techie super user with 21+ years of computer experience)

The Problem from Windows is that the policy is that all products must be work together with explorer and internet explorer, is one in this chain with a error all ist stop. The system is not error tolerant !! The software is not good on the border of every program exact definitiv and jump not to a special error handler. Learn with a flow chart than we would like not more  to kill you if we work a week to restart our computers

I've been getting a few computers having this problem.

After searching and trying for hours I descided to reinstall windows.

This actually works fine and while having the "windows.old" folder there's no need to spend hours trying to backup files as you can just copy-paste it from there.

this IS a vista problem. I have never had such a problem using Windows 7.

I have a similar issue with my vista 32 bit laptop hanging after the crcdisk.sys in safe mode. My interest is also about your statement re: "windows.old". Is this created by installing the OS afresh? This is important to me as I have not backed up a lot of very important recent files.

Any help from the community in clarifying this much appreciated.

I just fixed this problem a few hours ago. I did not have a windows vista installation cd nor did my acer come with a recovery cd. 

I had to do some searching for a "Vista Recovery Cd". The file should be around 120mb. Burn it as ISO onto a cd and boot off the cd. Repair/Restore did not work so I ran command prompt as the last option in the recovery menu.

I typed in "bootrec.exe /fixmbr" and "bootrec.exe /fixboot". Restarted and problem gone. I hope this works for you.
