Copying the Windows folder isn't likely to help. I'm not sure Safe Mode would have worked, either, since you couldn't even see a boot screen.
Sorry about the Recovery Console thingie. It's daunting for people who haven't worked in DOS. What you would be moving is any drivers that are marked as unsigned, to a new folder you create to temporarily house them.
Having a UBCD
would be nice because you could then save your data to a pen drive/thumb drive or somewhere and then reinstall from scratch, getting rid of all that's bad in the process. (Always good to stay backed up!) But even that requires that you know where your files are and how to copy them to another device.
Failing to load driver.cab means that your system cannot install drivers. (That's where they're kept so that they can be installed to match your equipment. They're usually stored on your hard drive.) You might try to do the repair install yet one more time, but you may have the same problems. Make sure the disk is clean and free of scratches. If you could get into the Repair Console, you could check to see if C:\Windows\Driver Cache\i386\driver.cab folder already exists.
Doing a Repair Install usually means backing up your data and favorites/bookmarks and so on after you get it running and then doing a full install later anyway, because the Repair Install will not solve all your problems, and may even create some problems of its own.
