RE: [Xen-users] windows vps can not start after a reboot

["Dustin Henning" <Dustin.Henning@xxxxxxxxxxx>]

        I haven't seen any other messages in this thread, so forgive me if
this has been said already, but I believe NTLDR is the first file loaded
from the Windows partition.  If you have an HD with a boot sector and wipe
the Windows partition (or lose the Windows HDD that is separate), you will
get something to the effect of "NTLDR is missing."  That said, I suspect
that your error implies that something has messed up or corrupteh your
Windows partition.  If you were using GPLPV drivers and something went
wrong, they could be the culprit.  That isn't to say you shouldn't use the
drivers, just that you should always have a good backup, as is often stated
regarding said drivers (and best practices in general).

That's probably the first dll that windows tries to find on bootup, and 
basically means it couldn't even find the correct windows partition.
Assuming 
this is not a new install of the gplpv drivers, and that you have previously
booted correctly with them on, there is another possibility.

When it happened to me, it was because my boot.ini file got altered. Instead

of something like 'multi(0)disk(0)rdisk(0)partition(1)' in the various
lines, 
it had the wrong partition number. Double check it. With the vps shutdown,
try 
mounting the partition (losetup + kpartx + mount for a file: backed vbd, or 
simply kpartx + mount for a phy: device, like an lvm partition), and correct

it if necessary.

Good luck.
