Fedora 10 from usb stick?


Does install from usb stick goes swiftly as installation from dvd media?
And is it enough to extract iso image and copy it to stick to make it work?

Whereas there should be no significant differences as to the speed, you can not simply copy an ISO to an USB key and expect it to work; actually, you can't even copy a CD ISO to a blank DVD and expect it to work, although they are both optical media.

Yes it seems it is not possible to install any operative system from usb stick,i saw it wrong in bios that options.Those options listed as usb apply to devices like usb floppy and usb cdrom not an usb stick.Whatabout install from hard disk?Would that be possible?I realy want to avoid burning dvd and installing dvd rom just for this purposes.

Hmm... I'm afraid you got me wrong. It IS possible to install from a USB stick if you have the right data format. ISOs are not the right data format -- they are "literal images" of CDs or DVDs, so they only work if burned to CDs and DVDs. On the other hand, there is no such standard for USB sticks that would be analogous to the ISO standard for optical media. A USB stick is usually just a storage device to your computer, very similar to a hard disk. Now, would you copy an ISO to your hard disk and expect it to boot? Well, it wouldn't.

That said, there ARE distros you can install from USB sticks, such as Mandriva and Damn Small, but those are not ISOs. They are actually complete bootable installed systems, just as the one you're reading this thread from. And they're not meant for installing, really, they're meant to be used out-of-the box. You boot the USB key and get a working desktop environment, all this without touching the hard drive.

As for your initial project, I have good news: although simply "copying" an ISO to a USB stick won't do, the following procedure WILL:

If you are interested in running (not just installing) the system from a usb stick you may also want to look at persistent overlay.

Of course, you can install from an USB stick. You can use Live-USB_Creator to create a bootable USB stick from any iso.

However, for this to work, you need to have a system which supports booting from USB stick.

I found the option buried in my BIOS. I placed "Boot from USB device" as Number 1 above CD-ROM and Hard Drive. After several failed attempts to boot from my Flash Drive (usually resulting in a Windows XP boot screen), I discovered that my computer recognized my flash drive as a secondary hard drive (not as "USB device"), so I simply had to list the flash drive as number 1 priority and my internal hard drive as number 2. Now, if I boot my computer with the flash stick in the USB port, it boots to the flash; if I want to boot Windows XP, I leave the flash drive disconnected.
