Secure Boot Violation I cant get back into reality...

June 12, 2014 at 16:52:58
Specs: Windows 8, i7, 8gb ram
I have a Samsung Np940x3g laptop, It came with windows 8. After trying to update and upgrade to windows 8.1 and realized how annoying windows 8 is, I decided to downgrade to windows 7 via USB Flash Drive (no disc tray included in laptop) When I was about to install windows 7, I decided to delete all the partitions that came with the laptop, that included all the recovery partitions as well. As it was installing windows and everything was looking good I got an error. This error will not let me get into recovery mode, or bios or anything no matter what function key I press. I figure its because I deleted all the partitions and the computer has nowhere to go.

The error reads: " Secure Boot Violation" Invalid Signature Detected. If this error persists, seek technical assistance. (reboot)

All I want to do now is just install windows 7, I absolutely hate windows 8. I have no clue how I can fix this problem. I spoke to Samsung and I am to send in my laptop for repair. However I would like to fix this by myself. I have a windows 7 usb flash drive and I would love to get it running again. Im very curious as to what Samsung would do to fix this problem because it seems like there is nothing left to do, especially when I cant get into recovery.

The simple answer here is to send it back to Samsung who will more than likely restore your computer to it's original state. The second thing to do is to learn to use Win 8 which is no different to Win 7 except for the bells and whistles. The third thing to do is to leave well alone until you have sorted out all the whys and wherefores of the system.

I realise that this may not be much help to you but it is the only way to go. Bear in mind that if you do decide to revert to Win 7 you have a days work of drivers to find and install.

"I decided to delete all the partitions that came with the laptop"
I do that on every laptop I work on, when changing operating systems.

" I figure its because I deleted all the partitions"
Correct.

Try disabling secure boot and enable legacy boot (switch from UEFI booting) in the bios.

OK so I was able to get into the BIOS now. My problem is when I select boot order and select general usb flash disc and restart the cpu to read from the flash I get this error


"Reboot and Select a Proper Boot Device or insert boot media in selected boot device and press a key


When I goto boot order, General USB Flash Disc" is the only option I have.. Is my usb stick not compatible?

" Is my usb stick not compatible?"
To isolate the problem, try the stick in different comps.

It is possible that the USB install stick was not properly made. If you know someone who has an external USB DVD drive, you can go the old fashioned way and install from DVD instead. The DVD you purchased or the option of downloading the ISO image to burn a DVD may be easier to deal with for you and may work more straight forward. Otherwise, you can try the stick on another computer or just wipe it and recreate it (make sure that it is bootable).

You have to be a little bit crazy to keep you from going insane.

I would suggest you stick with Windows 8. If you can't get on with the touch screen stuff then either install the freebie "Classic Shell" (which produces a standard start menu) or wait a few months for the next major Windows update, which will almost certainly do so.

From the desktop you can produce all the old icons you had on Windows 7. If you have any difficulties let us know so that we can help.

Always pop back and let us know the outcome - thanks
