Windows boot manager

There could be some system conflict triggered after the said changes. To help you with your concern, we suggest that you perform a clean boot. A

Lenovo G50 stuck in boot loop after windows update

Hi,

My computer is Lenovo G50 with windows 10. After my windows updated itself yesterday it got stuck in boot loop. It has a black screen with Lenovo text and error message saying "Install windows. Windows could not complete the installation. To install windows
on this computer , restart the installation." When pressing OK or X it boots and repeats the text.

I was able to get into windows 10 boot menu by pressing reset button. I tried to start in Safe Mode but then the text changed "Can't install windows in Safe Mode".

Any help or suggestions appreciated.

 

Quad booting

I would use Grub if I were you to.manage the OS boot list rather than Windows boot manager. I've had much better luck over the years that way...more stable, easier to fix, easy to modify.
