Create bootable iso file


I want to (re-)install Ubuntu in my computer (actually just to reactivate the grub) but I had a bad surprise: my DVD player does not recognize any CD anymore so I have to boot Ubuntu from USB stick. I have downloaded ubuntu 10.10 from their website but it's just a ISO file, and when I try to boot from USB it says no bootable file...so the question is.. how to make that ISO file bootable? thanks in advance!

You can use unetbootin to put ubuntu on the USB stick and make it bootable; if you're on linux, you can search on the repositories of the distro you're using.
(Btw, I think this is more suitable in one of the support forums )

Regards.

Thanks a lot!!!

now another question: my usb stick has a capacity of almost 4GB, it is currently `empty` because I deleted all files on it, but it still says only 800MB free.... are there any hidden files and how can I get them?
thanks again .

Hmm, I'm not sure, maybe there are hidden files there? Try executing ls -la inside the USB stick, or maybe du -ha | sort -n (I'm not on linux right now, so I can't test the last command to see what exactly it does, but I think it should show you which file(s) are there and their size).

Regards.

Sounds like the partitions might have been messed up.
Probably best to just format it.

Here's what I suggest:

Code:
sudo apt-get install gparted && sudo gparted /dev/disk/by-id/$(ls /dev/disk/by-id | grep usb)
This will open GParted, in which you can then select "Device -> Create Partition Table" (which will erase the drive) and then create a new fat32 partition.

I think the OP cannot get Linux to boot.
