Unable to boot from USB

Long story short my computer cant boot from a bootable usb.

Long story long, Yesterday i tried to format my computer with my windows 7 original disk, my computer does not have a slot for a cd player so i plugged one in and it was just laying there on the ground, i put my windows disk in and it was vibrating like crazy so i wanted to move it on a pillow, while doing so i tilted it a bit at it and it completely ruined the cd, i cant boot from it anymore so i lend a bootable usb with windows 7 on it, and put my bios priorites to boot from the usb and it gives me a screen with lines going down in different colors ( Blue, green, light blue, red) With Weird compination of letters ( C á L O( @ C, ) and so on. Like the same effect of a blue screen, i cant press anything and only thing i can do is turn it off and on. What causes this? Its not just this usb its also if my computer boots from my extern harddisk ( Without windows7 files on it just picutres) So im guessing the usb isnt bootable? Or is there a setting im missing in the bios.

Thx for reading my rambeling

Setup:

intel i7 3930k
gigabyte x79 ud3
gtx 680
840 series samsung ssd
Kingston usb.

Hi Strufly

You cannot boot from USB by copying from CD.
The CD is able to boot, as it is installed a small file for the disc-drive for enable to boot.
BIOS do have USB option, but is only if there is an OS is installed in the USB.
Reading and booting is both separate function.

The 2nd problem is the SSD. Click to the link to read about SSD installation.
SSD - Install and Transfer the Operating System

You can get an external DVD disc drive to do it.
But you need to read about how to do it.


Should you do not understand, post here so that someone may able to follow up with you.

I've got to disagree with you here. You can just copy the contents of a Window 7 iso to a USB if you prepare it first. WinRar will unpack an iso. I use diskpart commands - in an elevated cmd window -

diskpart
list disk
select disk 1 or whatever
clean
create partition primary
select partition 1
active
format fs=ntfs label="windows 7" quick
OR
format fs=fat32 label="windows 7" quick
assign

then copy the files from DVD/iso to the pendrive and the USB will boot. I have installed 50+ times using this USB method. You can also use Rufus to create a bootable install USB.

When installing from USB it is a bad idea to set USB as #1 in boot sequence - when machine restarts during install process, it will begin the install again unless you are quick and pull the pendrive out. Much better to use 'one time' boot menu for initial boot, then leave USB in until install is done. One time boot menu is often F11, but YMMV.
