Is the username an email address?
Without a CD or flash drive, the only option would be trying to reload Windows which would wipe out everything.
Do you want to try to reset everything?
If so, press F8 repeatedly on startup, this should give you a menu of various options.
Let me know what the options are
you're pressing F8 repeatedly on startup?
Try F10 or F11 as well
ok what are the options? Is it pretty clear, is there a restore option?
boot option what do you mean?
oh, sounds like you're in the bios
Are you doing this on the Windows 7 or 8?
The Windows 8 should have a built in recovery partition for sure, try the F8 or F11 on that one.
