As I understand, "(hd0,1)" doesn't refer to an extent of data, i.e. it not a file or a block list that can be opened like a file. "(hd0,1)+1" is the first sector of the partition. But "(hd0,1)" is not all sectors of the partition. It the partition name. It can be used in the "ls" command, whereas "(hd0,1)+1" cannot.

By the way, the current GRUB just failed to install on my test system.
After I rebooted it, GRUB hung on startup after showing "GRUB".

Please run a regression test, if you can.

The installation was broken by that patch, so I reverted it. It's easy to check the installation by doing it on a mounted flash drive, so that the real boot device is not at risk.
