Daul Boot with external hard drive


Hey guys my name is Hal and I recently got into linux. Right now im daul booting red hat 9 and ubuntu 5.10. The whole daul booting thing gave me an idea, and i wanted to know how i can do it. Lets say i get a nice external hd, and i format it with one partition on it. Lets say i install my ubuntu on the external hd(btw this is a usb external hd im speaking of)First i want to know if its possible to install linux onto an external hard drive, i dont see why not, and the next thing i want to know is if i can take that external hd with linux on it and the kinux file system and take it with me whereever i go so i can but into the ubuntu that i have on the external hd. I think ive heard this done with with a usb thumb drive so im pretty sure its possible here- i just need some instructions or directions to instructions. also one more thing one of the computers that im going to use the external hd with is probably going to be running windows and windows only, does that make a difference.

The usual way to attain dual boot capability is to install LILO or Grub or some other boot manager on the computer's boot sector (MBR). Obviously, your computer running Windoze only doesn't currently have a boot manager (does Windoze even offer a boot manager?). So, if you don't want to put Linux on this computer's hard disk, you may want to try making a boot floppy with Grub on the floppy, and set this computer's CMOS to boot from floppy. Now, i've never done this myself, but it seems doable. See the man page for grub-floppy to get started. Good luck, and let me know how it works.

Hey, i just noticed another thread: http://www.linuxquestions.org/questi...d.php?t=393244 Check out post #12. This guy (saikee) boots from a grub floppy routinely. You may ask him for more advice on this.

What exactly are you wanting to take from machine to machine?

Currently Knoppix allows for you to create a persistent /home directory on a thumb drive or similar. So you boot up from CD/DVD and pass a cheatcode to mount your persistent home (which could be your external drive). Here you could store any files, music, etc that you want to take from machine to machine.

The only issue I see with a linux distro on the drive would be changing hardware may give you some problems. Not sure if a distro, once installed, does hardware autodetect every time it boots...

What i wanted to do, but wasnt sure i could do it was carry around a external hd with a linux distro on it- i hear puppy linux is a good choice for kernel reasons- and also carry around a grub floppy, and I would be able to boot into my linux thats onto the external hd, whereever I am. My only problem is will the grub interface even see the external hd at all. I'm beginning to realize that this probably won't work because i dont think grub will even know that the external hd is attached. The other idea u gave me is actually a pretty good idea.

I did hear about one other way to carry around a linux distro, and that was to use Damn Small Linux (embedded version). Apparently you can put it on a USB key or whatnot and just boot it up from within either Windows or Linux. Haven't tried it of course...

I do at work use Cooperative Linux regularly. But it just runs on top of Windows. Not even sure if you can run it under linux... It's like a Virtual Machine. So that might be a pain to install all over the place.

I usually do the Knoppix route and keep any special config files or programs installed in my /home directory so that I can have them from place to place. The only problem I ever ran into was that some machines were too old to use the DVD version of Knoppix. But I just started carrying around both the DVD and the "Lite" CD version.

Are you just wanting to use linux instead of Windows at the library? Or are you trying to rescue people's systems? Demonstrate the power of linux to your friends? Just curious.

Best idea is to install Linux and GRUB on the external drive, and set the computer you attach it to to boot from that drive first. When you have the drive plugged in, it'll boot to Linux. Without the drive plugged it, it'll boot whatever OS is on the internal drive.

pljvaldez my reason for doing this would be to have the combination of my filesystem with all the imprtant files that i may need to transport around and also would have my favorite os with the programs im used to and enjoy. Of course i could always format an external drive with a vfat filesys and have it usable by both linux and windows, but i really want to have the linux os in my suitcase whereever I am. Hey madman this embedded version of dsl it work with other usb devices like the external drive right? and if it does- im not sure i ever heard of the embedded version- maybe u can give me a breif run through of the process of applying it and using or it would be great if u could redirect me to a tutorial or something

DSL embedded is just set up so you just run a batch file from within windows to run the system. The only downside, I think is that it has to share resources with Windows (i.e. RAM, processor time). Here's the link:

Just download dsl-2.0-embedded.zip from one of the mirrors, unzip it, and click on dsl-windows.bat
