Unetbootin - always "boot error" upon reboot

I'm having problems with unetbootin. I have tried the latest version and older versions but always end up with "boot error" when the grub menu should show up upon reboot.

I've read that the flash drive should be bigger than one gig (which it is) and that it should be formatted to FAT32 (which it is.)

I get no errors when unetbootin is setting up the iso/files. Nothing unusual.

Might anybody have any ideas why no matter which way I go, separate iso I downloaded or one built-in I always get "boot error" and never see the grub entry for unetbootin?

Wow. Nevermind. Formatting it to ext3 works. Wish I would have done that sooner.

I'm having a similar problem.
I've downloaded a debian 'live' .iso file.
I've also formatted a partition on the 32gb USB in FAT32.
I even mounted the partition via the terminal because I'm using debian (not Windows).

Then I opened up Unetbootin and it copied the .iso file onto the USB partition.
However, when I boot from the USB I get 'boot error'.

So is the previous comment correct, and I should format the partition to ext4 or something?
Also, should I mount the partition manually or will Unetbootin do that anyway?

If you read the home page for unetbootin you will this comment under Installation and Screenshots:

If your USB drive doesn't show up, reformat it as FAT32.

I've always used FAT32 with unetbootin and don't recall any problems. Also, the OP in this thread refers to Grub but unetbootin uses syslinux/isolinux as the bootloader. If it's not booting, something else is wrong but it won't hurt anything if you want to format ext2/3 and try again.

I'm looking to install debian and the debian manual says bootloader pgms aren't necessary.https://www.debian.org/releases/whee...h04s03.html.en
A simple command on a debian distro on your hard disk will make a live USB for you:

Code:

# cp debian.iso /dev/sdX

# sync

I also got an alternative command from replica9000 which I overlooked:

Code:

dd if=debian-7.7.0-amd64-netinst.iso of=/dev/sdc

I want to copy a particular 'live' hybrid .iso onto my USB. My debian OS on hard disk labels the USB as sdg. I'll need to make sure the USB is unmounted first.

I'm thinking I could try this:

Code:

root@host# cp debian-live-7.7.0-amd64-gnome-desktop+nonfree.iso /dev/sdg

root@host# sync



-or-



root@host# dd if=debian-live-7.7.0-amd64-gnome-desktop+nonfree.iso of=/dev/sdg

Would either of these commands be correct?

The dd command above should work if you run it from the directory in which the Debian iso resides.

Wow. It worked perfectly!
I can't understand why there are so many live usb creators. A simple linux command is all that's needed! Thanks very much!
