I fixed this on an IBM systems (x225 and x346) with RAID devices by makeing changes to the RAID Mini configuration program
during boot.  I had t set it to not use the legacy partition table and set he deault partition from 2GB to 8GB.

On an x220, I fixed it by setting the make boot partition visible in the BIOS.

What kind of box do you have?

[Unattended] NTLDR not found and wrong disk geometry





Hello,

I'm writing this to both lists, as I saw some occurences of this problem
on both.

We ran into the infamous "NTLDR not found" problem when using recent
Unattended snapshots. We nearly changed everything in the Linux boot
disk, but nothing helped. The old Unattended worked fine, the CVS
version didn't. True SATA disks (sdX devices) seem to be unaffeced, but
IDE-emulated SATA disks or true IDE disks (hdX devices) seem to be
affected *sometimes*, not on all machines.

After some debugging we found out that the culprit seems to lie in
parted. Parted up to version 1.6.22 works just fine. It prints out a
warning message

program parted is using a deprecated SCSI ioctl, please convert it ti SG_IO

but it works just fine. parted beginning with 1.6.23 does *not* work
fine. It creates faulty partition tables that lead to corrupt Windows
installations. Even cfdisk or fdisk print out that the partition seems
to be NC (non compatible).

I read that Patrick tried to fix this by the /proc/ide/hdX/settings
device, but in our case, it does not seem to help.

Patrick, are there any news to this? Can I help you in debugging, or is
this a truely parted-related problem you can't do anything against?

Thanks
Florian
