[ILUG] Dual boot Win2k and RH7/7.1

[David Crozier]

Came across this and thought some may find it useful!!  I have tried it on a
dual setup on a Toshiba Tecra 8000 and worked fine.

Dual-Boot Setup
Having got Red Hat 7.0 installed and bootable from a floppy, you can go on
to make the machine dual boot Windows 2000 or Linux without needing
floppies. Start in Linux with a blank floppy disk inserted (not the boot
floppy!) and run:

  mount -t vfat /dev/fd0 /mnt/floppy
  dd if=/dev/hda3 of=/mnt/floppy/bootsect.lnx bs=512 count=1
  umount /mnt/floppy

Then shutdown Linux and boot Windows, and from a Command Prompt run:

  C:
  cd \
  copy A:\bootsect.lnx BOOTSECT.LNX
  attrib -s -h boot.ini
  copy boot.ini boot.ini.orig
  notepad boot.ini

and edit boot.ini so that it reads e.g.
  [boot loader]
  timeout=10
  default=C:\bootsect.lnx
  [operating systems]
  C:\bootsect.lnx="Red Hat Linux 7.0"
  multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000
Professional" /fastdetect

then run:
  attrib +s +h boot.ini
  attrib +s +h bootsect.lnx

Next time you boot, after the Dell logo, you'll get a text screen saying:
  Please select the operating system to start:

  Red Hat Linux 7.0
  Microsoft Windows 2000 Professional

  Use ^ and v to move the highlight to your choice
  Press enter to choose.

Note: After any Linux kernel rebuild, you'll need to re-run LILO, make a new
Linux boot floppy, and re-copy the new Linux boot sector to Windows all over
again. Otherwise, you won't be able to boot Linux any more.
