Hi Steve I'm not a grub expert, but I think the wiki [1] tells me you don't call grub-install on a partition (sda1) but on a device (sda). The grub-install command that should work would therefore be: grub-install --target=i386-pc /dev/sda1 [1] https://wiki.archlinux.org/index.php/GRUB - Patrick Steve Downes <steve@xxxxxxxxxxxxxxxxxx> schrieb am So., 2.

It is not a new laptop, it isn't UEFI.I installed by using a USB installation key & following the Arch instructions through which seemed OK until I reached install grup install. I thought all was well. The 1 hard disk was formatted as follows:- /dev/sda split into:- /dev/sda1 ext4 30gig to hold whole OS /dev/swap /dev/sda3 ext4 Approx 100G /homegrub Install command was grub-install --target=i386-pc /dev/sda1 I think that covers it.
