Why can't I boot to a clone image with UEFI?

March 24, 2015 at 09:38:08
Specs: Window8.1
This tablet is driving us nuts. The USB port broke some solder joints and wasn't holding a USB plug very well(still works at a specific angle). We ordered a new MB from Dell, but it didn't have any software on it. After lots of struggling with it, we managed to clone the original drive to an external hdd. We can't figure out how to make it boot to any external USB drive. Seems to be a problem with UEFI. We have secure boot disabled, but can't figure out what to point it to to make it boot from the external drive. We've tried with the original MB and the new MB. Don't know what else to try, most things we've found online deal only with the specific situation being asked about. If someone could point us toward a good general guide or give us a specific solution, we would appreciate it.

Dell Latitude 10 ST2 running Windows 8.1

It should also be mentioned that Dell Latitude tablets do not allow BIOS compatibility mode, UEFI only.

It might be down to the cloning method - see here:

Thanks for the reply. Paragon was the utility we used to clone. It was the only one that worked.

Silly question maybe but did you check that the bios has a USB boot optoon and that it's set that way as the first boot device?

Yes, the USB boot support is set to enabled. When it recognizes the external drive automatically we set it to highest priority, but it doesn't always create it's own entry. Nothing we've tried makes it boot, using it's own entry or any efi file we've pointed it to. We did have a bit of success, got a flash drive to boot rEFInd. Trying to learn efi shell commands and understand what needs to happen next.

If the board is exactly the same as the old one, there should be no reason to make any changes to the hard drive or OS. Just swap the board & go.

Would love it if it was that simple. The drive is just a solid state chip on the board. The new one didn't come with anything loaded. The key sent with it won't work for a new install and there were no disks with the originals.

I know this won't help but I guess it is not beyond the realms of possibility that the new board is faulty, or lacking the UEFI firmware. Maybe you should try returning it as faulty.

Otherwise, is it out of the question to swap the USB socket off the new board onto the old one then going from there? It's hard to know without seeing the board and how the socket is soldered in - might be an impracticable suggestion and even if possible a very good soldering skill would be necessary. These things are done in a solder bath during manufacture.

It could be resoldered, but the new MB was ordered first and we have to send the old one back. Can't really mess with it in that way. The UEFI firmware looks the same and has the same issues booting to USB with both boards. Thus far the only thing that will boot is the rEFInd software or windows on the original board. When booting with rEFInd the clone tries to boot and gives an error about a file missing or damaged. Windows\system32\winload.efi Tried copying from another identical tablet, but access is denied, even though it's plugged into a pc. It won't even copy from the command prompt or from a dos based boot cd.

Thanks for all the replies, never know when someone will come up with the right idea.

"Can't really mess with it in that way"
Sure, I understand completely from your amplification"

same issues booting to USB with both boards"
Aha, I probably missed that point somewhere. Makes me think that there must be something wrong with the clone but no idea what.

We ended up calling Dell. They sent us a one time only installation usb thumb drive that would actually boot. Ended up doing a clean install and setting things up the way we had the old one. Not thrilled with the Dell Latitude 10 ST2 tablets. Thanks for all the replies.
