I've downloaded kubuntu 12.04.3 LTS .iso and tried to install it on a flash drive to install the system on my hard drive. I've tried to use usb-creator-kde 3 times and unetbootin once and each time the USB flash drive was omitted by the machine startup - the grub just opened like there was no flash drive plugged. I think that my USB flash drive has the booting ubuntu installed correctly, but I have no proof of that.
I know I had to set up BIOS to read from USB and I did, unfortunately, no effect. This is my BIOS setup:
Boot Option #1 USB Hotplug FDD Boot Option #2 SATA Optiarc DVD RW AD-7560S Boot Option #3 SATA HITACHI HTS542525K9SA00 Boot Option #4 MBA v10.7.5 Slot 0200
I'm using lenovo ideapad Y530.
Is there anything wrong here? Can someone point me on what to do?
