I recently (19.03.2015) purchased Dell Insp 15 3543 (Ubuntu OS). As I wanted to Dual Boot Ubuntu along with Windows 7, I did not complete the Ubuntu installation (Pre-provided with Laptop, & started Installing windows 7 from Installation CD. While, at the option of selecting where to install the Win 7 OS, I deleted all partitions: A. Partition 0 OEM Recov[300 MB], B. Partition 1 [3-4 GB] probably where the Ubuntu OS /Ubuntu Setup was on and C. Partition 2 Free/Unallocated Space [Rest of HDD])

Now everything worked correctly until just after completing the installation I discovered I accidentally deleted OEM Recv Partition also.

And afterwords while I was Installing Ubuntu from USB (bootable drive), the Ubuntu installation did not detected the Windows 7, (even though if I normally boot /Switch On my laptop, laptop was normally and correctly loading Win 7 and also showing C Drive (OS) and other drives (that I created, just after Win 7 installation was complete.)

Now my problem is

  1. Can I get the OEM Recovery partition back? does this mean that I have to sent this laptop to the service centre of Dell OR Dell will provide some CD that will do the work.

  2. Does deletion of OEM Recovery Partition is causing the problem of not showing the Win 7 as OS while installing Ubuntu 14.04 LTS

Please help me out here, I really want both systems on my laptop. If further info needed, do tell me !

Note: --My laptop came with Ubuntu 14.04 Pre-Installation Setup. So is OEM deletion is really the problem? I just checked my partition is not Dynamic its basic only.

Also the Laptop was on UEFI mode (from where the boot option was Ubuntu) & not on Legacy. B4 installing Win 7 I changed this to Legacy

  • Yes, and maybe. you may be able to recover those partitions using testdisk but it's unlikely as you've probably overwritten all that in your attempt to install Windows 7 where you amde the major mistake of deleting all partitions prior to installation. 2) No. NOTE: Requests regarding Windows software are extremely likely to be considered off-topic here and will likely be closed as such.

  • OK! thanks, but see i did not know that and secondly then what is the workaround if i only have Windows OS as of now! & i dont know but is there any software that works from ubuntu bootable usb and does the same work ? Also note that this is brand new laptop, there was nothing on it, except per-installation setup of ubuntu 14.04 – Drp RD Mar 19 '15 at 14:29
  • Also can can i use gparted or fixparts ?? how to use the same – Drp RD Mar 19 '15 at 14:34
  • Workaround: Boot from Ubuntu installation media you have on USB, choose try Ubuntu and then install Ubuntu and choose to run alongside Windows Your OEM recovery partition will still be gone but I doubt you'll need it since it came with Ubuntu and you have 14.04 on USB. did you happen to convert your Windows partitions to Dynamic? This may be one of your actual problems. – Elder Geek Mar 19 '15 at 14:36

  • In Windows disk management the partitions will be labled either Basic or Dynamic http://www.learn44.com/wp-content/uploads/2011/06/Dynamic-Disks-Microsoft-Disk-Management-Console-www.learn44.com_.jpg – Elder Geek Mar 20 '15 at 01:01
