Hi, I'm having a frustrating problem, and i was really hoping someone could help me. I installed Windows 7 64-bit as a partition on my hard drive, so I could run both Windows and Mac OS X. Recently, I got a message upon startup of Windows 7 that "the program can't start because %hs is missing from your system". I searched a little around, and I found out this was due to a stupid AVG (free antivirus software) update that they released!! Of course, now it's been taken down, but many users, including myself, can't log in! Here is where it gets worse. To fix this problem, AVG released an .iso, which could either be placed onto a CD or usb key to be then booted upon startup, and then the AVG program could be bypassed (because it was apparently the one causing problems). So, I burnt the .iso onto a CD using Toast, double checked that it was set to burn .iso and restarted into Windows 7 while repeatedly pressing the Delete key. However, I only get into the boot setting, not the BIOS settings which I need in order to change the boot order to CD being first! I searched, and I don't think there's another way of booting from a CD in Windows 7 other than changing these BIOS settings. Unfortunately, I searched even more, and apparently, you can't access BIOS settings at all on the mac! Please help me! I hope I don't have to reinstall the whole damn Windows 7 partition from scratch because of some stupid free antivirus software update!
