Hi, When I have installed debian jessie and archlinux (20150501) onto two brand new Samsung 850 SSD grub fails to install to boot record. Jessie with ef02 partiation and legacy boot on HP6930 (only efi, no uefi). Archlinux on ef00 and uefi on HP2570 with grub on uefi partiation (fat32, 2048 -> +512M). What's solved both problem was to install LILO, (chrooting), check if computer boots from hd and then reinstall grub and this worked both times. Grub installs to boot sector when disk is "used". A msata Samsung 850 SSD (new) in msata to 1,8" sata adapter don't need this "treatment". It works flawless. Know I have the same issue again with ubuntu-mate 14.04.2 and brand new, Samsung SSD 850 sata! This time I will try a wheezy dvd and grub first before I try LILO. So I made google on the subject when waiting for the iso to transfer to usb stick. Suspect firmware issue with the brand and or grub 2.02? I will try this in morning, (UTC +2). Diff-1 Your problem was after upgrade Diff-2 I use sector 64 to 2047 as ef02, doubt this matters Diff-3 amd64 Best Regards Jimmy Jönsson BIOS was buggy, why would UEFI be better?
