[21:22:03] <guest_32> please who can tell me what 'sardu' is ?  is it an OS, or multiple OS's  or what lets a DVD hold multiple OS's  or is it something else ?   please help
[21:24:58] <camerongray> guest_32: It seems to be a piece of software that allows you to build a bootable CD/DVD/USB that can hold multiple different operating systems
[21:25:39] <camerongray> So you would boot the CD and it would let you pick between multiple linux distros and it would then start the one you picked

[21:29:58] <guest_32> am starting to get it a little bit.      so  first of all: what makes a DVD/cd/usb  bootable  is it the OS itself or another software that is separate but is included in the DVD ?
[21:30:37] <camerongray> It's another piece of software called a bootloader, That "GRUB" thing that you see when booting some linux systems is an example of this
[21:31:25] <camerongray> A bootloader is technically a very small operating system that's job is to start the main operating system
[21:31:46] <guest_32> am sorry am familiar with Windows not with Linux
[21:32:45] <camerongray> Ahh, Windows has a bootloader too
[21:33:22] <camerongray> It's the program that the computer first runs, this tells the computer where to find the operating system
[21:33:43] <guest_32> ok       so the bootloader is what is actually making the DVD+the OS bootable?
[21:33:48] <camerongray> Exactly!
[21:34:39] <guest_32> ahh   got it thank you so much , I really apriciate it
[21:34:47] <lostcoast> the ISO file system helps too :P
[21:35:14] <guest_32> what is that by the way?
[21:35:16] <lostcoast> and using a program to burn the ISO file if its a dvd/cd
[21:36:22] <camerongray> guest_32: An ISO is an image of a CD, it contains all the information that was contained on the CD in such a way that it can be burned back to a disc and the resulting disc will be identical to the original
[21:36:41] <lostcoast> sardu is a program that allows you to have a few bootavle programs on one device that you can choose which one you want to boot
[21:36:52] <lostcoast> bootable*
[21:37:22] <lostcoast> device = a usb storage device
[21:38:33] <guest_32> but the sardu is not what is booting the device ?
[21:39:05] <lostcoast> ISO is an image of a CD<<no its a bootable file
[21:39:35] <camerongray> guest_32: No, Sardu is a program that configures another bootloader on the device, that bootloader is most likely GRUB or similar
[21:39:48] <lostcoast> ISO are often used on cd/dvd's
[21:40:18] <camerongray> You could do the same job without Sardu but it would take a lot of really complicated configuration, Sardu is a tool that makes it easier to do
[21:40:31] <guest_32> ok
[21:40:53] <lostcoast> camerongray: read the intro  http://www.sarducd.it/
[21:40:58] <camerongray> I did :P
[21:41:23] <camerongray> lostcoast: An ISO is a CD image but can preserve bootable information, it doesn't HAVE to be bootable although many are, you can also have an ISO of a music/data CD for example.
[21:41:26] <lostcoast> The multi bootable device can include comprehensive collections of antivirus rescue CD, utilities and popular Linux live distributions. Windows PE can also be included, as well as recovery disks and install media for Windows XP (Professional, Home and 64 Bit), Windows Vista, Windows Seven and Windows Eight.

[21:43:15] <lostcoast> *sigh*
[21:43:24] <camerongray> lostcoast: Yep, I have a very similar setup, really useful, 64gb USB Drive (USB 3.0 so super fast) with loads of diagnostic tools, distros and Windows installers, I no longer need to take a pile of DVDs to fix a PC, just one USB drive
