Hello everyone. I need to backup a windows 10 laptop which I don't use, but need to provide support for. This is a UEFI machine with secure boot enabled.
When I plug in a custom devuan install I have on a pen drive which I've setup for such things, the system doesn't even recognize the drive is plugged in when in the boot menu. This is most likely because this is a system with grub2 booting from MBR which works for my other use cases. So, I decided to dd the devuan Chimaera minimal live amd64 UEFI iso to a pen drive. When I try to boot with the minimal live drive attached, the drive is recognized, but I get a message about invalid signature, secure boot violation. Pressing enter on that just takes me back to the boot menu. Is there some way for me to get a valid signature from the existing windows 10 install on that machine, and remaster the minimal live iso to include that? Removing the MVME drive and just backing it up on another system is something else I've considered. However, to do so, I need to remove a sticker over one of the screw holes in the case, which would void the warranty. This is something I don't want to do, and I also don't look forward to cracking open this thin laptop case. I also hesitate to disable secure boot. Even if I could do that on this laptop, I would need someone else to read the UEFI screens to me while I did that. From what I've read, disabling and enabling secure boot isn't just a simple toggle operation. I also don't want to make the existing windows install unbootable before I backup the machine. So, remastering the minimal live image to have a valid secure boot signature seems the simplest way forward. Any help on figuring out on how to get a valid signature, and remastering the iso image would be much appreciated. Pointers to web pages are good enough. This is my first time dealing with secure boot, so please excuse me if I'm slow on the uptake. In case it matters, the machine in question is an MSI GF63 Thin 10SCXR-222. Thanks in advance for any help.
