Can anyone explain BRIEFLY as to how to install OpenSUSE through an USB?. I searched in lot of forums, but i couldn't find anything helpful. Moreover, there was something written about installing it with the dd_rescue command, but that doesn't seem to work. So please give me a brief idea for installing OpenSUSE, through an USB.
If your BIOS supports 'boot from usb' as an option in the boot loader (cd, hdd, net, floppy etc).
You can create an bootable image on a usb drive. I've done so with Debian, but here is a howto for OpenSUSE I pulled from a search result that should apply to you.
Once you have your image on the usb (note that it wipes your usb) just configure your bios, and reboot with the usb drive inserted. It should boot from the usb and continue with the install.
Do you have an image file for the suse install you want? Usually the process is:
That is the best I can do without more information such as the operating system(s) you have now, what kind of computer you want suse on and if that computer has any OS already.
