G’day. I’ve had an oldish laptop (HP Elitebook 8770w purchased 2012) running Manjaro as my primary OS for a few years on a multiboot system (Manjaro and Win 10 on /dev/sda and Arch on /dev/sdb). During a recent large update I had to leave it running while I went out. When I returned some hours later the system wasn’t responding so I did a hard reboot.
It now will not boot up and shows the failures to start messages in screenshot below when attempt to boot into Manjaro (both 5.15.91-1-manjaro x64, the fallback initramfs, and earlier kernel 5.10.166-1). It also will not boot Win 10 any more, just gets to the spinning dots the reboots itself. It’s also much slower to get to the grub screen.
It does boot fine into Arch on the other hard drive. I suspected it was a hardware failure of the disk, but a bios disk scan said it was ok.
I’m wondering if it’s a filesystem corruption? But that doesn’t make sense why it won’t book to Win, does it?
How can I recover the data from each /dev/sda partition if I wanted to replace the drive or reformat and reinstall?
