[Bug 1037217] [NEW] (UEFI install) Windows not detected due to recovery partition

[Evertjan Garretsen]

Public bug reported:


After looking throug many forum entries i managed ubuntu to see the
installed windows 7 by removing the windows recovery partition.
(WARNING: don't do this if you are not familiar with reinstalling
windows without using the recovery tools for your computer)

I booted windows and removed the partition in windows. After restarting
the Ubuntu installer windows 7 was detected. I read somewhere this is
caused by a file that wants to be at the end of the disk and that a
minimum of X blocks on the end of the disked should be reserved for
this. Using gdisk before i removed the windows recovery partition said:
“overlapping the last partition by xx blocks"..

I wanted to dual-boot Ubuntu with Windows, but as i use Ubuntu 99% of
the time i just wanted Ubuntu to work, no matter what the costs. So i
deleted the recovery partition (after making backups of it using asus
tools). And Ubuntu installed just wonderful. Unfortunately the UEFI /
GRUB / MBR / whatever problems still don't allow me to start windows,
but hey Ubuntu is working just fine!
