As other posters have mentioned, you might have to mess with CMOS settings. I've also found that not all USB ports are created equal. So, N CMOS settings and M ports creates N * M combinations to test. Rather than using a Live distribution or an installer image on USB flash, I've found that: 1. I can install Debian onto a USB flash drive. 2. I can place a Debian system drive image onto a USB flash drive. David

1. Make two partitions on the dongle. One big enough to hold GRUB's
files and the other sufficient for the -amd64-standard.iso.
2. Format the smaller partition vfat.
3. Install GRUB to the MBR of the dongle and with its files on the
formatted partition.
4. dd, cp or cat the -amd64-standard.iso to the second partition.
5. Write a grub.cfg. Here is one of mine you can adopt:
menuentry "Debian Live KDE" {
search --label --set=root "Debian Wheezy 20131014-01:18"
linux /live/vmlinuz2 boot=live config quiet splash
initrd /live/initrd2.img
}
uuid is an alternative you could use to 'label'.

Seems new enough for that feature. So check the drive boot order and change as required. It will boot MSDOS from a fat32 formatted USB dongle. But apparently, it won't boot an isohybrid formatted USB dongle. It has nothing to do with drive boot order.

Re: how to make bootable live wheezy USB that doesn't use isohybrid
> I'd like to make a live wheezy USB dongle. I followed the instructions on Why wheezy ... it's old. I have been running wheezy for about 5 years without any problem. The machine has two partitions / and /aux. I attempted a fresh install of jessie in /. But the install failed and the machine won't boot. It appears that the kernel in jessie tickles something in the hardware that wasn't tickled by wheezy. I will likely upgrade the firmware. (Dell Poweredge machines have a lot of distinct firmware components besides the BIOS.) But before I do, I want to get the data off the /aux partition. So I want to boot something that I know works. >https://www.debian.org/CD/faq/#write-usb > > to make a live USB from > > http://cdimage.debian.org/mirror/cdimage/archive/7.11.0-live/amd64/iso-hybrid/debian-live-7.11.0-amd64-standard.iso There are many ways to make a bootable HDD image if this can be booted. By using aufs or newer overlayfs, you can choose to make OS persistent while your running system writing on RAM(tmpfs). https://wiki.debian.org/DebianEeePC/HowTo/InstallOnSDcardOrUsbStick I have not tested but this may give you hint. I also use kvm to install system on USB connected HDD from my working Debian system. many ways ... I don't need it to be persistent. I just need to get enough of a root shell to run tar|ssh to get the data off of /aux. /aux is /dev/md1 which is RAID5 across /dev/sd[a-f]2. So I need enough to be able to mount that read-only. Then when that is done I will upgrade the firmware and reattempt a jessie install. So I'd appreciate help getting the easiest way to get a root shell with tar, ssh, and mdadm. The issue is that the machine is too old to boot isohybrid from USB. It needs to boot msdos from fat32 on USB. See other emails in this thread. Jeff (http://engineering.purdue.edu/~qobi)

From where are you going to get a non-hybrid Wheezy .iso? I have come across computers that won't boot from USB for various reasons, but never one that will boot from USB, but won't boot from hybrid.

how to make bootable live wheezy USB that doesn't use isohybrid
I'd like to make a live wheezy USB dongle. I followed the instructions on https://www.debian.org/CD/faq/#write-usb to make a live USB from http://cdimage.debian.org/mirror/cdimage/archive/7.11.0-live/amd64/iso-hybrid/debian-live-7.11.0-amd64-standard.iso but apparently my machine, an older Dell Poweredge R815, won't boot from isohybrid. Can someone point me to a howto for making a bootable live wheezy USB dongle that doesn't use isohybrid? Thanks, Jeff (http://engineering.purdue.edu/~qobi)
