Hi, thanks for the reply.
I know the SSD is not totally dead, as it shows up in the BIOS menu, and if I boot from a USB stick into GPartedLive, I can see the disk and its partitions.
I can enter the BIOS by holding ESC when turning on, (or F7, followed by selecting Setup rather than the Windows boot manager). F2 and F8 don’t do anything, and the BIOS page has no option for any sort of safe boot/repair mode.
So I think booting from some sort of USB recovery stick is all I can try. Do you know if there is something provided by Chuwi for this, or it is something I get from Microsoft?
Thanks
Tom
