I've got a Toshiba Satellite L305-S5924 laptop running Vista Home Premium 6.0. It's able to boot normally, but it's filled with crud that I want to remove with MalwareBytes and ADW Cleaner and stuff like that (basically going through all this: http://malwaretips.com/blogs/malware-removal-guide-for-windows/), so I'm trying to boot it into Safe Mode With Networking. I can press F8 and get into the advanced boot options and choose SMWN, but when it starts pulling up files, it seems to hang up at crcdisk.sys. I tried running Startup Repair, bootrec.exe /fixmbr and bootrec /fixboot from the System Recovery Options, but they all say nothing is wrong. Am I just being impatient, or could there be something bigger here?
