This bios-from-hell doesn't have the kind of boot-order configuration to which I (and I suspect most others) am accustomed, as in floppy, usb, cd-rom, hd1, hd2, etc., so half the time in bios is spent writing down which configurations didn't work, before trying another one. The one that seems likeliest renders only the infamous black screen with blinking cursor. The way that previously worked was to let the UEFI drive boot grub, whence I'd hand it all off to the grub entry for the Linux installation on /dev/sdc1. It would then boot, quickly, and checking mount determined that I was in fact running off the / on sdc1. But now it does not do that, at least not entirely. I can select the sdc1 installation at the grub menu -- but it goes ahead and boots sda1 anyway. I've gone so far as to chroot in to /dev/sdc1 and run update-grub there. The result is as expected, with the first item on the menu being the /dev/sdc1 Linux. the sda1 fstab: /dev/sda1 / ext4 errors=remount-ro 0 1 /dev/sda3 /home ext4 defaults 0 2 /dev/sda2 none swap sw 0 0 UUID=8C5E-D456 /boot/efi vfat defaults 0 1 the sdc1 fstab: LABEL=BOOT / ext4 errors=remount-ro 0 1 LABEL=HOME /home ext4 defaults 0 2 LABEL=swap none swap sw 0 0 UUID=8C5E-D456 /boot/efi vfat defaults 0 1 The labels point to the same debvices/partitions except for the first one -- LABEL=BOOT is /dev/sdc1 -- and the swap, which are on sda2 and sdc2 respectively. (sda1 has the label BOOT-HD, fwiw.) -- dep Pictures: http://www.ipernity.com/doc/depscribe/album Column: https://ofb.biz/author/dep/
