6 I don't think so. Can your system boot from a USB stick? If so, see
7 https://wiki.archlinux.org/index.php/USB_Installation_Media for
8 instructions on how to make a CD ISO bootable off a USB stick. Note
9 that this is for legacy boot. For UEFI boot, see
10 https://wiki.archlinux.org/index.php/UEFI#Create_UEFI_bootable_USB_from_ISO
11
12 1) If you haven't already done so "emerge sys-boot/syslinux" to get the
13 "isohybrid" command.
14
15 2) Get a USB stick. *WARNING* all data on the stick will be erased
16
17 3) Assume the ISO is install-amd64-minimal-20130516.iso Execute the
18 command
19
20 isohybrid install-amd64-minimal-20130516.iso
21
22 4) Insert the USB stick. *DO NOT MOUNT IT*. Unmount it manually if you
23 have an automounter.
24
25 5) As root, execute the command...
26
27 dd bs=4M if=install-amd64-minimal-20130516.iso of=/dev/sdx
28
29 ...where sdx is the USB stick (e.g. sdb or sdc or whatever)
30 - be careful not to overwrite the wrong device
31 - yes, it's sdx, not sdx1
32
33 6) You now have a bootable USB stick
