Good afternoon, I found out the rather hard way what caused those boot failure problems that were the subject of a threat starting last month. After my weekly "dnf upgrade" last Thursday, I checked my root e-mail, and found the hard drive had 8 bad sectors, then 16 bad sectors. A smartctl short test showed several parameters "pre-fail", and the others "old-age". I obtained a new drive. My Cray Research friend gave me a USB stick with "Clonezilla-Live-Version" on it. That duplicated the old hard drive onto the new one, but apparently not 100%. After the old drive was removed and the new drive installed, I could not boot. The system was being put into a grub shell(?). (It displayed the "grub> " prompt.) After beating out heads against the wall (or the phone), my Cray research friend gave me another USB stick with "Boot-Repair-Disk" on it. That rebuilt a grub file, but not correctly. But at least I got a grub menu when booting, and I was able to edit the shell that the grub menu entry would run. I had to take the "efi" off the commands "linuxefi" and "initrdefi". That allows me to boot up Fedora. But the menu is missing an entry for windows, and I still have to edit that script every time. I want the grub menu to offer the three most recent patches of Fedora, the most recent Fedora rescue shell, and windows-7, in that order. (This is a dual-boot system.) And I want the shells launched by the menu entries to be correct. How do I get that accomplished - the correct Fedora-25 way? If it matters, the motherboard uses UEFI bios. Thank-you in advance. Bill.
