I downloaded a live ISO from the web and saved it as debian7.iso.

I then I flashed it onto my USB:

dd  if=/home/debian7.iso  of=/dev/sdb

I rebooted my computer, and set it to boot from "removable boot", but I cannot install from the USB stick.

Why isn't this working?

i solve it by google.

menuentry 'Debian wheezy in usb ' {
    load_video
    insmod gzio
    insmod part_msdos
    insmod ext2
    insmod loopback
    loopback loop  (hd1,msdos1)/hybrid.iso
    linux   (loop)/install/vmlinuz iso-scan/filename=/hybrid.iso root=UUID=D0F8-2160
    initrd  (loop)/install/initrd.gz
}

Please flesh out your answer to make it more useful to readers. Where is the menuentry held? –  suspectus Jul 6 '13 at 8:33

A "better" way to get a USB stick booting with a Linux disk may be to use "unetbootin", which actually builds the distro on the disk and installs a bootloader - which I believe you will find a more reliable way of booting it.

@it_is_a_literature:

It helps to state the make & model of your system, not just so you can get an answer, but also so that others facing the same problem can be better informed.

I would not recommend Unetbootin. In my experience it does not work with Debian 7 or its derivatives.

dd if=/... of=/... bs=4M; sync is the best way to write the iso to usb pendrive.

Boot to usb by adjusting your boot device order in the BIOS menu (usually accessed by hitting 'F2' at power-on).

At GRUB menu:

Scroll down to 'Install'.

Press 'tab' key.

At bottom of screen, some text will appear.

At end of text:

Press 'space' key.

Enter (without quotes) 'vga=normal fb=false'.

Press 'enter' key.

The installer should now initialise.

This works for EeePC 701 series.
