The description of Boot-Repair-Disk - Play With New Friends
Fix A Busted Computer That Won't Boot For FreeBoot-Repair-Disk is a free boot utility that can fix MBR and other boot sector problems on Windows machines. It does this by using a very stripped-down installation of Linux, which features a utility to repair most boot problems and little else. It works with lots of hardware, particularly if that hardware supports UFI, but on the other hand, Boot-Repair-Disk is not open source meaning it is impossible to see exactly what it is doing and how it works with your device's most sensitive pieces.
