Many computer users might have faced the message “ BOOT
SECTOR VIRUS. PROCEED Y/N? “ during Windows installation thus not allowing to
install the operating system or you to boot operating system if already
installed. Some motherboard manufacturers have put boot sector virus protection
in BIOS. Boot sector is the first sector which contains DOS boot sector or commonly
known as MBR (Master Boot Record) of the hard disk drive or floppy. MBR
contains information about your hard drive partitions details and from where
the operating system has to boot.
If the boot sector virus protection is enabled in the BIOS,
it won’t allow you to install operating system because during installation the
operating system writes boot code on MBR of the hard disk drive. If you are
trying to write anything on MBR, it will consider as virus. To solve this, you
have to disable boot virus protection in BIOS
If you are seriously infected by boot sector virus even
though you have disabled boot virus protection in BIOS, then scan your computer
with good antivirus tool or use Avira Antivir Boot Sector Repair Tool to remove
the boot virus. Usually boot sector virus will corrupt the MBR of the hard disk
drive or floppy.
There is another way of removing boot virus. Select “R” to
repair during Windows installation setup to go to DOS recovery console window. In
the command prompt type “ FIXMBR ” to repair corrupted MBR.
