#2285 assigned bug

Bootloader fails when chainloaded from grub 1/2 in a specific way.

Reported by: dustin howett Owned by: nobody
Priority: normal Milestone: R1
Component: System/Boot Loader Version: R1/pre-alpha1
Keywords: Cc:
Blocked By: Blocking:
Has a Patch: no Platform: x86


When I load my haiku partition (/dev/sda2) from GRUB Legacy as such:

chainloader (hd0,1)+1

I get a read error (bootloader debug turned on)

From GRUB 2:

set root=(hd0,2)
chainloader +1

I also get a read error

BUT, with GRUB 1 and

root (hd0,1)
chainloader +1

The bootloader works just fine.

This is probably a bug in GRUB, but I think it might be related to int 13 and how the bootloader uses it; when GRUB reads the disk BEFORE chainloading, there is no issue, but when only the first sector is loaded, the boot fails.

Hi, is this bug still valid? Did you run makebootable after installing (Installer should now do it for you)?
