Re: [Xen-users] fresh xcp 1.6 & xenserver install fails on first boot (kernel not found).

Hi Errol - so I went through the rescue disk boot, mounted /dev/sda1, and once 
mounted I looked for /boot/extlinux.conf - and found it - also found a 
/boog/extlinux folder with lots of files in it - I wondered if part of the 
issue was a bad mbr - I found examples of people initializing the mbr by 
copying the mbr.bin from the extlinux or syslinux install.

I don't see one in the extlinux folders - this is xenserver on the machine at 
the moment - but I found /usr/share/syslinux/mbr.bin

So I did:
cp /tmp/sda/usr/share/syslinux/mbr.bin /tmp
umount /tmp/sda
dd if=/tmp/mbr.bin of=/dev/sda

When I rebooted I got a different result.

Missing operating system.

I know that the syslinux mbr file probably isn't right for the extlinux in 
place - so now I'll try to track down an extlinux mbr file - I figured it was 
worth a shot. But I don't see one in the installed xenserver. Maybe I'll find 
one on the xenserver iso.

Thanks - any more advice / insite appreciated - still wondering if I will get 
past this only to find xenserver / xcp are missing a driver or if it's really 
all just about extlinux not installing properly for some reason.

Does anyone know if there is a way from the xenserver or xcp iso to force a 
reinstall of extlinux?

Thank you all,

Mitch.

I'm probably several threads behind on this one, but the grub bootloader is not 
a part of XenServer/XCP. It uses EXTLINUX

Is your RAID device a fakeraid device?
