Booting problem in PC |
 |
|
One fine day you start your PC and get messages that say,”Book
Disk failure”. The problem is that the hard disk is detected
but the OS does not load. The system may get stuck in the
second screen during the booting process or the OS might display
an error message and refuse to load. Such situations can be
trouble some as they leave you with very few troubleshooting
options
One of the common problems in dual boot systems is of the
boot loader getting corrupted. For example, you have a system
running Windows XP and Linux using Lila as boot loader. If
Lila gets corrupted, you can not boot into either OS.When
this happens, you have to boot into the system using some
other media, such as a boot floppy or the Windows Dafter booting
go to the command prompt, type ‘fdisk/mbr’ and press
[Enter]. Note that if you use Windows 2000 or XP, boot into
the recovery console and give the command ‘fixmbr’
to clear the MBR. Unfortunately, after you restart, it will
boot to Windows directly, without any option of booting into
Linux. You will have to restore LiLo again from your Linux
CD, or reinstall boot loaders such as XOSL from Windows.
If your problem persists, or if you never used a boot loader,
than boot into the system from a boot floppy or the Windows
CD.Windows 2000 and XP users should boot into the recovery
console. Go to the command prompt and give the command fdisfk/mbr’and
then give the command ‘sys C’. This clears the MBR,
and makes the bootable partition C, Windows 2000 and XP users
should give the command ‘fixmbr’ and’ fixboot’
C: to do the same. Then restart the system to boot into the
OS.
If you still have trouble, you might have a virus on your
PC’s boot sector .It is difficult to confirm an infection
without a virus scan. Thesymptoms of an infections-applications
slowing down or many unrecognized files appearing in the system-should
give you a clue. For example Windows 98 and Me users might
see a message during boot up that says,” No valid FAT
on boot drive” this is caused due to a boot sector virus
called stoned Monk. Even reinstalling Windows might give you
an error message that says, “Your computer already has
an operating system installed”. Then best solution is
to connect the hard disk to another system, and scan with
an anti virus tool. You can also create a rescue disk for
the anti virus tool and scan the system using it.
If nothing mentioned above seems to work. Then you have a
serious problem at hand. Connect it to some other system and
try to access the data if you can, then your boot record is
damaged. Otherwise the service center beckons.
