Dual Boot (MBR Concepts)
The MBR is the very first sector on every hard drive. The MBR isn'ta file and isn't part of the file system. It's accessed with drive configuration utilities such as FDISK, Partition Magic and similar. The MBR also contains the drive's master partition table (there could be additional partition tables in extended

load a sector of MBR and run it?
Anyway, here's a quick comparison of the two as I understand them: Install-mbr only installs a master boot record, whose function is to: 1) Determine which partition to boot from (from user input or by default) 2) Call the boot code located in the first sector of the chosen boot partition, which then is responsible

MBR and Partition table ?

copy mbr
Windows makes a backup of the master boot record, and reports any modifications. Hope you tried fdisk/mbr from a clean w98 boor floppy, then you should encounter no problems. A viral infection (prior installing w98, infecting win.com and others) can't be excluded, though. Also, maybe you was loading some special

Bug#15524: bin86 breaks mbr package.
This is where I made my second mistake, I decided to use Win 98 rescue disc to restore the original MBR. As a result I have returned to my (pre-linux installation) Win98 default boot option. Right. Plus, it would appear I, have destroyed the Linux partition information. This is unlikely. The contents of the MBR are

example: mbr wiped.
Running the /mbr switch copies the backup mbr to the mbr. If there is any problem with the backup (virus, for example) you may continue to inherit it. I always thought fdisk /mbr deletes the master boot record, and kills any virus residing in the boot sector. Funny thing tho, if you have a virus in the mbr I have

Dual Boot (MBR Concepts)
We have to write an assembler programm that changes the "Magical Number" in the MBR from 55AA to 0000 so that the machine will not boot after the changing. The project is called "mbr virus" but is more a Assembler exercise... Unfortunatly my assembler skills aren't that good as they should be -( so I wanted to ask

installworld failure (sys/boot/mbr)
If anything else (eg an OS installer) re-writes the MBR with standard code, the bootability of the FAT32 volume will fail. There was no warning to the user, in my tests, when the normal boot sector was blanked ...thus implying a vulnerability should the MBR code be replaced in the course of installing another OS.

newbie help with MBR
I just wanted to know if windows 95 wrote to the mbr, like NT does with nt loader. If so, how does it do it differently than NT? Because, as I understand, if I install NT and Linux in the same computer, their loaders will try to overwrite each other in the mbr. Does the same thing happen with windows 95 and Linux?

FDisk /MBR Question
I tried two counts because grub docs stated that the stage1.5 information would be stored in probably unused space directly after the MBR.
