I've just spent considerable time creating a reply to daddle, just before posting it failed authentication. I'll paste what I composed in the hope thatyou might read it and also pass it on to him. Hi daddle, First let me tell you that I also have a message from Gehringer who has offerred suggestions. I should like to now give a history of this problem thus far. I have spoken to my friend who kindly tested the DVD I use for recovering the Macrium Image, the USB stick I use for for Macrium Recovery and the USB stick used for recovering Windows 10 which I created using the USB creation facilty which appears in Control Panel. This offers the option of backing up the system files by ticking a box and is probably the reason why the USB stick(s) I have been creating take up more space than the procedure you suggested I use. My friend tells me that his PC runs Windows 10 version 2004. It is a PC he built himself using a GA78LMT-USB3 R2 motherboard with a 64 bit AMD PhenomX4 processor. Each of my bootable recovery devices successfully boot on his PC, but not mine at this time, but this situation improved once I had disabled the 'Fast Boot' option in UEFI/BIOS. Even before I disabled the 'Fast Boot' option I was able to 'see' that the boot order was correct. With a bootable USB stick insered and a bootable DVD mounted in the drive I was able to see the LEDs on both of these devices flickering after executing a 'Restart'. Please accept that using the UEFI/BIOS at the boot tab it clearly states the boot order is FIXED which to me means 'unchangeable'. I then disabled 'Fast Boot' resulting in me being able to boot the Macrium Recovery USB stick which I believe was created in 2018 on the Windows 10 PC I was using at the time which has sadly broken down, and the reason I've bought the Medion PC, and the Macrium Recovery DVD. But it will NOT boot the W10 recovery sticks which I have recently created. I have also created a 'new' recovery USB stick for Macrium Reflect using this PC, but this fails to boot in the same way as the W10 recovery sticks. This I think proves that there is nothing wrong with the boot order. Now you may be thinking why I'm bothering about this, I have the means of recovery using Macrium. I am old and may be considered cynical but I have developed my thinking on the lines that if something can go wrong it will go wrong. If my Macrium Reflect fails I SHOULD be able to recover using a W10 USB stick, but I can't, it won't boot. So why is this? It boots some media, but not others. Might this be a problem with the UEFI/BIOS or might it be a problem with the software used to create USB sticks? Please bear in mind that the recently created Macrium Recovery stick, using Macrium sotware, fails to boot as does any W10 recovery USB stick. Perhaps, as two sticks created with differing software both fail, this might point to a UEFI/BIOS problem. Disabling Fast Boot improved matters, but might it still be too fast? The mother board is Medion B550A4-EM 1.0 The UEFI is American Megatrends Inc. 550A4WOX.105 11/13/2019 I have referred to the provided user manual regarding PowerRecover. I see I have the app available BUT this user manual seems to have been written for PCs using Windows 8. Do yoiu think it will be safe to use this in order to 'Create driver and tool rescue USB disk'? I don't have a USB disk suitable, perhaps the author means USB stick? You suggest I should revert to the system as it came out of the factory which was W10 1909. Are you thinking on the lines that the Media Creation facility in the 1909 version could be different from what is now available in 2004? Remember tha Macrium Media Creation also build a USB stick which fails to boot. You ask about the 4 Gbyte USB stick, all I recall is that it was greater than 4Gbyte, the stick I create from Control Panel uses 8.8Gbyte. I realise that this PC, MD 34280 was only launched onto the market late in August. Unless I've bought a 'Lemon' I suspect there may be others out there with similar problems especially as they may not be aware of how to access UEFI/BIOS to change the 'Fast Boot' setting. Perhaps, like many PC and Laptop owners do, they think their PC will never go wrong. They may have created a USB recovery stick but whether they check it is another matter.
