[comonda2]

i want to set up kubuntu to my new ssd with usb.but bios doesnt recognise.

kubuntu iso file is ok.I've set up it before.

md5 is correct.

usb is ok.

bios works with the last version.

so what is the problem? must i use another program?

In your BIOS, under "Boot Devices" or "Boot Sequence" or something like that, you need to set USB as the first boot device.

no bios doesnt detect.the option you said will selectable when only bios detect usb device.

You must do a little troubleshooting.

(1) Does your computer recognize ANY OTHER USB device?

(2) Is your Kubuntu Live USB drive recognized on ANY OTHER computer?

(3) Does your computer have "Secure Boot" set in BIOS?

(1) Does your computer recognize ANY OTHER USB device?
yes
(2) Is your Kubuntu Live USB drive recognized on ANY OTHER computer?
i didnt control yet
(3) Does your computer have "Secure Boot" set in BIOS?

no

If your Kubuntu Live USB drive is not recognized at all, in any running computer, then there is a problem with it.

If it is recognized as a USB drive in another computer when running, but that other computer also will not boot it, then there is a problem with the way it was created (it was not correctly made bootable).

If you have a good .iso (as you indicate), IMO the best way to make a good live USB is by using the command dd, as explained here in my how-to:

when i boot with legacy mode, bios recognise usb but it shows only black screen with writing curcor.so i cant set up.

OK this says there is no problem with BIOS, there is a problem with how the ISO was installed on the USB stick.

no, i write usb on win10.

This is most likely your problem. As Qqmike says, best results come from using dd.

Source for dd for windows: http://unxutils.sourceforge.net/

CAUTION: dd is very powerful and absolutely unforgiving of errors. Be very, very sure you understand what you are doing with it before you run a dd command.

actually i didnt understand anything from the link.rufus said me if ur usb doesnt boot, try wirte with dd mode.but rufus created 2,5 mb disk when i selected dd mode.rufus doesnt work.so which program?

[vinnywright]

try using this https://etcher.io/ it's an easy one and their are both linux and windows versions for making live USB's.

Vinny, yeah, I just downloaded etcher (from my Kubuntu) and tested it on a flash drive, seems to go very well. Maybe I'll add this brief note for comonda2:

Setting up:

Download the etcher zip file.
Rt-click, Extract here.
That gives you the file etcher-electron-1.4.5-x86_64.AppImag .
Simply double-click the file etcher-electron-1.4.5-x86_64.AppImag, then follow the GUI. The GUI will continue to inform you of its progress.
