Are those iso files bootable and because im guessing not, could someone make those bootable? I cant get unetinbootin make a working usb stick. It could be so easy to download iso and ff if=/livedvd.iso of=/dev/sdc ...

If someone has a working bootable usb stick with live cd or dvd could You please ff it and share the iso somewhere?

command is ff if=/dev/sdx of=/livedvd.iso

unetinbootin doesnt make working bootable stciks on arch either so why not make them bootable at once and get rid of the problem. I dont want to install windows for this..

The Gentoo livedvd should be bootable or at least it worked the last time I tried it. The livecd/mininstall CDs should be bootable (it works when burned to a real CD), if that doesn't work, something is wrong with unetbootin.

A lot of people (myself included) like System Rescue CD. Instructions for putting that on a USB stick are here.

The first instructions on the System Rescue CD page use "isohybrid" to modify the iso image so that it can be booted.

MY reason why i kept or buy notebooks only wiht optical drives.

USB sticks just hardly work regarding booting

I also tried drivedroid for android. Which makes iso images bootable for your android phone. worked only for a few isos in many.

I saw recently as I did a backup, my grub from my backup usb 3.1 drive in an exernal case was recognized by my UEFI.

When you want less fuss, you may consider getting an USB optical drive

Much easier to use isohybrid :)

boxi markus # isohybrid /home/markus/Lataukset/livedvd-amd64-multilib-20160704.iso
isohybrid: Warning: more than 1024 cylinders: 2173
isohybrid: Not all BIOSes will be able to boot this device

boxi markus # dd if=/home/markus/Lataukset/livedvd-amd64-multilib-20160704.iso of=/dev/sdd
4450304+0 tietuetta sisään
4450304+0 tietuetta ulos
2278555648 bytes (2,3 GB, 2,1 GiB) copied, 655,042 s, 3,5 MB/s

It works :)

You don't need to use unetbootin or isohybrid on any Gentoo Linux medium as all ISO images are hybrid and can be all dd to any removable writable media.
