Ive had this happen one too many times while distro hopping..... If only I had my system repair disks on me all the time like I do now

:( haha, how unfortunate.

lol just need this again it always helps

I remember this happening to me mid-2011. It sucked. I had Windows x64 dual booted with Ubuntu. I then wanted to remove Ubuntu from the computer because it was annoying how it would automatically start up at boot. I wanted Windows 7 to be the default boot. But when I finished uninstalling Ubuntu and I restarted my computer - it went all black. I couldn't figure out why the computer wouldn't start up. I went onto another computer, Googled the topic and found out the Boot Manager had to be restored. Bam! With those few little letters put into the Command Prompt - Windows 7 was all up again. Great article. Thanks.

1. Download and install Windows Login Recovery in any available computer.
2. Run the application and insert a USB flash drive in computer.
3. Click Local Account and USB, and click Burn to burn a password reset USB drive.
4. Click Ok when the 7 password reset USB drive is created.
