Title:
  unable to upgrade to 20 from dual boot v18 and XP

Status in grub-installer package in Ubuntu:
  New

Bug description:
  I have been trying to upgrade my dual boot system which has v18 and XP
  to v20 + XP. no luck.

  I cloned the old setup to a new drive and tried various ways to
  install 20 from a usb drive.

  Somehow setup is not recognising XP.

  1. I deleted the old ubuntu drive and fixed the XP MBR issue. XP loads
  ok but installing v20 did not recognise the XP installation. I tried
  the proposed fix in XP by running chkdsk in administrator mode but no
  luck.

  2.I tried to install on top of v18 on the fully working clone. The
  setup was only able to see v18. It did not see the XP. system started
  to install but failed eventually.

  hope you can help
