I formatted my hard disk and its now bringing me bootmgr is missing and it is not readinf anything from Windows installation disk. What should I do. Am using lenovo
Can you pass on the model of your laptop? An SKU would help. If you can get into BIOS, look into the Boot Device's priority list and set it to your bootable USB installer(after it's plugged into an available USB port). Mind if I ask what OS you are intending to install?
