[SOLVED] grub: booting CD

lord_didger · 12-02-2006, 11:26 AM

Hi,
I usually use Debian etch but I need to run Windows sometimes. My bootloader is grub. I wanted to boot CD with windows' installer and later to boot Windows which would be located in /dev/hda4 so I had written to /boot/grub/menu.lst

Quote:

title Win
map (hd0,0) (hd0,3)
map (hd0,3) (hd0,0)
rootnoverify (hd0,3)
chainloader +1

title CD
map (hd0,0) (hd0,3)
map (hd0,3) (hd0,0)
chainloader (cd)+1

However it didn't work. What should I change to boot cd directly?

These are partitions on my disk:

Disk /dev/hda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hda1 1 65 522081 82 Linux swap / Solaris
/dev/hda2 * 66 1370 10482412+ 83 Linux

Booting from CD is not really related to the partition setup, grub, etc. It is managed thru the BIOS. When you start the computer, there is a key to press (eg DEL) to put the bios in setup mode. In one of the setup menus will be the boot sequence. The normal setup would be floppy 1st, CD 2nd, and then the first harddrive.

You only need to change the boot sequence from your BIOS.

Once this is done, you can re-install your GRUB from the linux control panel. Every linux distro has an option to re-installl GRUB and this can be accessed from the control center with root privilege. GRUB should automatically detect any installed Windows installation. While configuring GRUB set Linux as you default boot and give timeout as 10 second. You work is done.
