GJ has been having "issues" with her laptop, one of which is that Windows Update has been refusing to update (from what I could see it was just failing to install the anniversary edition). Fortunately, it finally decided that it could install that update earlier and that's when the problem started.
Once Windows has started, you don't seem to be able to do anything (I have manged to get Task Manager up, which doesn't really indicate much of an issue, apart from 100% disk usage for a while), but other than that nothing. I've tried System Restore, but it hasn't been turned on, so there's nothing to restore. I can't get a command prompt up (oh, I can from the troubleshooting options, but I'm not actually sure what to do now I'm there), and it doesn't want to boot into safe mode (choosing any of the safe mode options just seems to freeze the laptop at the initial Fujitsu logo screen). Next step seems to be a system repair, (I've just tried the Start-up Repair option, but it said it couldn't repair anything), which seems like a last resort, is there anything I've missed?
