Use a boot rescue CD, and burn it on a friends computer.
Some of them are on a list here:

Run an update on you virus scan. Then do a complete scan on your system. Your anti virus program should be able to detect and clean or even quarantine the virus.
In 1986, the first PC virus was created. It was the Brain virus from Pakistan. Brain was a boot sector virus and only infected 360k floppy disks. Interestingly, even though it was the first virus, it had full-stealth capability.
Boot sector viruses can either infect the Master Boot Sector (MBS) or the boot records as you're talking about. Boot sector viruses are actually the early precursor of modern day viruses. Even so, they are still annoying and should be dealt with appropriately.
Not necessary. If you get one of those boot viruses which puts itself in the boot sector even after complete disk format you will still have it. But in most cases complete formatting of the hard drive and fresh installion of OS gives you virus free OS.
If a virus persists on a PC even after formatting it is likely that the virus has been inserted into the boot sector of the hard drive - which is not rewritten when you re-format it. Assuming you are running a Microsoft OS, to fix it, boot using the install CD for the OS and run the first Repair option which will load the Recovery Console from a ramdisk (and doesn't use the hard drive for booting). This requires that your BIOS supports booting from the CD drive. Then run the 'fixboot' command. This is supposed to overwrite the boot sector. You may have to specify the drive letter of which partition to fix.
A boot sector virus is a virus that's located in or directly modifies a special part of the hard disk in a computer called the boot sector. The boot sector, in basic terms, directs the computer to the things it needs to load the operating system and user interface so you can use it. Viruses that modify the boot sector can be loaded into memory at the same time or even before the operating system, and can prevent the computer from starting up correctly in some cases. Boot sector viruses were more common during the days of DOS, when such viruses had easier access to the boot sector and other sensitive parts of the system. Today, these viruses are not very common because it is more difficult for them to spread and infect.
u make ur computer all clean then u will see what happen to it
because on your electronical there might be a virus and to get rid of the virus you will need to scrap everything on the device. hope this has helped you .
Reason for black screen:When the computer will not boot up, it sound like it is booting as the CPU fan is running and the lights are on. It also finds the CD ROM but it won't boot from a CD either.Sometimes when you have a computer black screen on startup and the power switch light will be green and then turns to orange or amber. Everything is running.Everything seems to be running but you can't see anything on the screen, not even a flashing cursor. Your black screen in Windows has occurred before the Windows logo screen.
If you would register and log in, you can block those things you don't like.
Windows can't pick up any virus' hence why we have anti-virus, even if it could while any PC is booting it has a sequence, booting up different hardware then software at different points so it's possible it will boot up the floppy disk drive but not read it.
Mainly Trojans and Worms, but some can happen without even booting it.
