Hi all,
This will be a bit long but please bear with me - I needed to give full details of the issue and what I've tried!
I bought a Cosmos VIII 17.3" with SSD 256Gb and i7 9750h, with Win 10 Pro x64. I've barely used the laptop, though it booted up fine the first four or five times I had switched it on. However the last time I switched it on the OS loaded and the laptop crashed suddenly. The laptop required a hard shut down and since then, the laptop hasn't gone past the PC logo when I switch it on.
I can access the bios, and the SSD is showing. I thought the issue is with the OS, so I tried creating a USB reset disk to reinstall the OS. But it gave an error "No signed device drivers were found" once it hit the screen where you select where to install the OS. It did see the partitions at this point, though it cleared the screen once I clicked next, and it displayed the above error.
I used the CMD within the USB to check diskpart. The disk is visible in there, again, and the volume info suggests it is usable. I tried using the clean command in this to clear the partition but that also returned an error, and nor could I switch the partition from read-only to write.
I have tried using the Usb in every port also, to no avail.
I have hit a brick wall here. I don't know if it's a problem with the usb or the PC itself. I can't create a new disk currently as I am away from home. I had to borrow a kind student's laptop to create the image in the first place - this kind Samaritan was a stranger and looked at me like I was an alien at first when I asked her for her PC. Desperate times...
Any suggestions would be greatly appreciated.
