Hi,
BitLocker is on my laptop and is used just after the loading screen - essentially cannot even get to Windows without going through BitLocker. I have used both the numbers on the laptop keyboard, as well as the F numbers. I also use Hebrew on my laptop (same
keyboard - just ALT+SHIFT), so if BitLocker doesn't work I alt+shift again to try it out. Also to test, when the problem happens and I have to use the recovery key, I ensure my laptop is turned on to US Eng keyboard layout when I next shut down, though it
doesn't seem to stop the error.
As far as I'm aware I cannot use the On Screen Keyboard for that part, until I actually get onto Windows. Though I might be wrong.
Using Windows Error Checking, no errors were found (phew!) - thanks for that lil' lesson.
I haven't yet tried to change it - just trying to find out why it's doing this first. I have the recovery key, so I can always get through, but it is rather mystifying knowing that I'm using the correct password.
