linux and linux - dual booting?


Hi,

I want to install both RH 7.2 and RH9.0. Is that possible with 2 different / partition and common /boot and swap partitions? if so, will it show both the OS while booting? has anyone done this?

thanks in advance

Its is possible. But u must install both versions in different partions.(both /boot and /swap).
this type of install. will show different OS during booting.

I am not very clear... u mean that both the OS should have separate /, /boot and swap partitions? i forgot to tell that i also have windows 2000. All these has to be done in one hard disk...

Thumbs up Multi-Boot

In my dotcom (no more) hayday I had 11 OS'es on a single harddisk.

You only need 1 swap partition, all linii will initialize it on bootup. You do not need /boot partiitions , they are a throwback to BIOS limitations of bootsector.

Windows is greedy bitch about boot sectors, install it first. Every linux you add will try to "take over" as welll, just let them go to it and continue adding oses until you're done then hack up a lilol.conf and run lilo -v , must use -v or the piece of crap won't admit to failure

I mean both Redhat versions can have different / and /boot partions.
I think u have windows 2000 installed in ur sys. i hope. then u need not worry about installing linux. Linux boot loader GRUB will take care of it. For that install Redahat 9 on system with windows 2000
By default it will install GRUB, which will take care of windows or redhat booting.
Thanks Mahesh

You couldo it like this:
hda
hda0 - Win2000 - ntfs or fat
hda1 - swap (for both linuxes)
hda2 - redhat 7.2
hda3 - redhat 9

I think...

THANKS!!

First all What a wonderful site!

second I have been searching for some Multi-booting nfo for about 1 month. Myself am also trying to multi boot. I have a request to mulit boot the following: Win98, w2k server, RH7.1, and RH8.0. from a 20 gig drive for observation purposes only. All boot except, RH7.1.

For testing purposes I am installing only RH7.1 and RH8.0 on one hard drive. here is what happens

I install 7.1 first and use LILO at the MBR and then 8.0 which I choose GRUB to replace LILO. At the Grub screen I seen both options but I gives me an ERROR 13 when selecting 7.1. 8.0 works fine.

Unfortunately I am not at work and will be returing at 7:00am tuesdays morning. (central time -6)

I appreciate the good work you people do.

Thank you!

is it really necessary to separate the /swap partitions for two different linux installations?

Firs you must make a partitions. I'm using BootIt for that purporse. Let's say you have 4 partitons. It should look something like this:
hd00 - ntfs (win2000)
hd01 - linux swap (swap)
hd02 - linux native (linux1)
hd03 - linux native (linux2)

After installation of win (or any other win) install frst linux to hd02 (in linux it's name woul be hda3), with lilo (or grub loader) installed on the boot sector of that partition (not on MBR). Than do the same with second linux. Swap space should be selected during the setup proces of the linuxes as far as I know (main distributions surely have that option. After all that is completed, configure the BootIt to be the boot manager and declare partitions hd00 hd02 hd03 as bootable...

Second possibility is to install wins first, and after installing linuxes to instal lilo (or GRUB) to the MBR, but configuring them is a little harder than working with BootIt...

I hope I've helped some...

For those using lilo:
http://www.linuxquestions.org/questi...hreadid=100378
http://www.linuxquestions.org/questi...threadid=99670
http://www.linuxquestions.org/questi...hreadid=102727

I think these threads should give you a pretty good idea how to multiply boot linuxes using lilo.
