Not quite sure what I have going on here.
Created HitmanPro USB on a Windows 7/64-bit laptop (running HitmanPro x64 to create)...
Boot attempt 1: selected to boot from USB, used USB boot option 1. Did about a 30 second loading files screen, then it went into a startup repair sequence, would not let me cancel (I didn't try cancel soon enough). Finished, could not repair/no file changes (it reported) and booted me to a normal startup (still infected).
So I went to boot attempt 2 and 3: Again to boot options, select USB, then get USB boot options, select 1, says its loading HitManPro USB.
Get the 30-second loading files screen, then in about 10 seconds a small Microsoft Window logo name appeared with a horizontal progress bar, this ran about 5 seconds...then PC shuts down. Same result both times.
Boot attempt 4: all same USB steps, loads files, takes me to startup repair dialog (which is same Lenovo screen background as in the recovery mode). Canceled this startup repair immediately this time. Which put me back into System Recovery Options. Doesn't this indicate that PC is not actually booting from USB at all?
Checked USB disc, has the three files installed as indicated in Hitman documentation.
Thanks for any further help you might be able to provide. May be blowing HD away and reloading is only option....
