Any way to manually make a bootable USB from ISO?
I've been using Unetbootin but it occasionally fails to create a bootable usb the way I need it to, especially with the newer versions.
Is there a way I could extract the iso myself?
Here is how to extract ISO to usb and make it boot able http://askubuntu.com/a/116886/35775
This question appears to be abandoned by the OP. Voting to close it.
This is a bit destructive, but works all the time. It will write everything to the /dev/sdb (which is the usb device. )
sudo dd if=/path/to.iso of=/dev/sdb bs=16Mread the manpage of dd
This will only work if it is a hybrid ISO containing an MBR and partitioning to allow you to use it as a disk image too. So it may or may not work for the questioner's case.
@JamesHenstridge: This is true, however, most "live CD" ISOs have this property. So, this method should work for most real-live use-cases.
`isohybrid` is a useful command for this purpose: http://superuser.com/a/592656/45927
@EhteshChoudhury that is how the kernel does it on `make isoimage`: https://github.com/torvalds/linux/blob/64291f7db5bd8150a74ad2036f1037e6a0428df2/arch/x86/boot/Makefile#L177
worked fine on my laptop when booted in live cd with ubunto
Depends. If you are going to use a Live Linux ISO like the Ubuntu LiveCDs then you can use the tool that comes with Ubuntu called Startup Disk Creator. Type
Startupin Dash and it should appear there. From there on, the disk creator can create a Live USB from any Linux ISO that is a LiveCD.If you are referring to a Windows ISO for example that changes everything. I suggest you see this question: How to create a bootable USB from a .iso file?
According to this tutorial it is possible.
Just use whatever distribution CD you choose in its place.
Note: Usually the failure to create a bootable USB is the USB itself. Some thumb drives just don't want to cooperate.
or a bad ISO...

Use the following Program:
Universal USB Installer Click HereThat's not manually.
@techtonik It's as "manual" as dd or any other piece of software that performs the same function.
@JasonC, are you sure that simple raw copy from ISO to USB is enough to make it bootable? I thought that you need to do some checks that ISO fits USB correctly and set some bits to make it bootable.

Extracting the ISO will not make a Bootable USB/CD/DVD
