I have created new flash drive by the article on Pendrivelinux (Windows install seemed easier than burning LiveCD and creating USB from that). I tried to boot up. Unexpectedly, nothing happened. I guess the booting from USB is not yet as easy as using CDs. In the end I was successful and I want to sum up the problems I had and solutions to them.
For instructions how to create bootable USB disc, see www.pendrivelinux.com.
The solutions may be specific for motherboard Gigabyte EP45-DSR and other related boards.
Problem: booting from USB does not start
Solution: Don't try to set the boot order differently. That does not work (at least for my board). When booting starts, press F12 to go to boot menu. Here, choose "Hard Drive" and select your USB with the system.
Make sure that the USB is marked as USB-HDD0, otherwise the system won't boot from it. It seems that the motherboard checks just the first USB device it finds and ignores the rest.
Problem: booting starts, but after a while, message "
end_request: I/O error, dev fd0, sector 0" is displayed periodically.Solution: The Live USB is trying to find the floppy drive. Switch off the floppy drive in BIOS. In my case, this is done in menu Standard CMOS Features. Set option "Drive A" to "None".
I hope this helps if you have similar problems.
