recover boot mrg with no disk drive

[jackie dee]

I erased the boot mrg by mistake, all I see is the black screen I cannot access anything in the system at all and have no disk drive, what can I do??

Make a bootable USB for your OS using Rufus and open a command prompt using the repair windows option

Then type
Bootrec /fixmbr
Bootrec /fixboot
Bootrec /rebuildbcd
