I am trying to revive an old computer of mine. It is a Dell Inspiron 9300 running Windows XP.

I am using unetbootin with Grub to install Lubuntu, however when I try to install after restarting the computer I receive an error message along the lines of this:

casper vmlinuz not found error 15

Is this install requiring an internet connection? I am not sure this laptop can connect to the internet in the bios, I also tried installing with an ethernet cable connected an was still unsuccessful.


look for a directory named /casper/ and change the file named "vmlinuz.efi" to "vmlinuz" without ".efi". or, if the file is named vmlinuz add ".efi" in the end. the answer is from this question, next time google before you ask

  • I added the extension to the vmlinuz file now I get another error 15: find --set-root /unetbtin/ubnkern – sawreals2 Jun 26 '16 at 20:48
