I notice “amd64” in the torrent file name.  
I suppose this will not work on an Intel Core 2 Duo machine…

I am pretty sure it just refers to the instruction set which is  
compatible  
with x86.

Just adding to that… amd64 == x86\_64 (as far as I know). It’s just  
called  
that because AMD64 because AMD designed the 64-bit extension. Whatever  
you  
call it depends on who’s marketing team got to you first 😉

Core 2 Duo can do 64 bits, so you’re good.

The cause why that image is called amd64 is that it follows Ubuntu’s  
naming scheme which uses “amd64” for images for the 64bit x86  
architecture and “i386” for the 32bit, now  
on-almost-any-machine-obsolete address size architecture (actually,  
both names are misleading… Ubuntu 13.10 amd64 runs on any x86  
processor with the 64bit instruction set, being produced by AMD, Intel  
or even VIA, and Ubuntu 13.10 i386 will _not_ run on a 386, even if it  
had enough memory; it needs the features of the i686 generation).

Greetings,  
Marcus

Hi!

I Installed GNU Radio live on a usb stick and I was changing some  
aspects of its configuration.  
I like to delete some entries of the boot menu (is to use with my  
students at class and I don’t one anyone to use “install ubuntu”) and i  
broke grub2. Now the usb stick does not boot.

I know hot to fix a normal grub2 installation, but as it is a grub2 on a  
casper filesystem I don’t know how to fix it. Any help please?

regards

AMD, Intel, and VIA all support amd64. Intel’s failed 64-bit effort was  
the  
Itanium (IA-64).

​What are you using to create the USB drive?​

​I expect you’ll find it easiest to start over from scratch.

For reference, when we create the live USB drives for our classes​, we  
use  
Unetbootin, then replace the installed syslinux and grub configuration  
files with these:

[https://github.com/gnuradio/gnuradio-livesdr/blob/livesdr-snapshot/custom/grub/syslinux.cfg](https://github.com/gnuradio/gnuradio-livesdr/blob/livesdr-snapshot/custom/grub/syslinux.cfg)  
[https://github.com/gnuradio/gnuradio-livesdr/blob/livesdr-snapshot/custom/grub/grub.cfg](https://github.com/gnuradio/gnuradio-livesdr/blob/livesdr-snapshot/custom/grub/grub.cfg)

These have the extraneous menu options removed and allow the user to  
choose  
between persistent and non-persistent modes. The syslinux.cfg controls  
the  
boot options when booting in legacy BIOS mode, and the grub.cfg controls  
the boot options in UEFI boot mode.
