Hi,
My Intel NUC with HA OS has been running for years, but now has a corrupted bootloader. If i reboot the system it says “Insert a bootable device and reboot”. Is there a command i can run in Ubuntu Live to fix the UEFI boot loader?
Try gparted live.
FWIW, I read a paper some years ago from google after the had used ssd’s for several years in their servers. They found time, I think on adv 6-7 years, was the number 1 factor for failure. Regardless of how many times the disk was written to.
