tldr:

  • have SSD + 2 HDD
  • tried to install Ubuntu (on HDD) next to Win 7 (installed on SSD)
  • couldn't install or 'try'; computer freezed everytime I chose one of those options
  • managed to install Ubuntu by turning of ASMedia Controler in UEFI and adding nomodeset (instead of 'quiet splash')
  • while booting having problems with "hard resetting link"
  • wasted hours; just wanted to go back to 'win-only'
  • opened windows partioning manager; looked for the 'linux' partition (which is not recognized by windows).
  • deleted it; booted; 'grub rescue', 'no such device'
  • noticed I made big mistake (never use windows to delete linux....)
  • Re-Installed Ubuntu with this guide: "http://linuxbsdos.com/2012/05/17/how-to-dual-boot-ubuntu-12-04-and-windows-7/"
  • used 'boot-repair-disk' to install new 'grub'
  • still no Windows 7 on startup boot manager
  • BUT I can use Ubuntu now (but I still have to use 'nomodeset' + turning off ASMedia Controler in the UEFI)
  • I can open every harddrive (ssd, too) when I am in Ubuntu. There's still a windows folder and everything else in my SSD.

QUESTION: How do I bring back my Windows 7? (also: whats the difference between turning asmedia controller 'on' or 'off'?)

this is what fidsk -l gives me:

PLEASE, let me know if you need any more logs or something else. I am pretty new to Linux.

thank you very much!

Why you are still trying to install Ubuntu 12.04 , install 15.04 its really easy they even show install alongside windows option . and do you have windows 7 bootloader in another partition ? it should be a 100 MB partition check it. and install ubuntu 15.04 with custom partitioning create /boot and / in different partitions use ext4 it should work fine after installing ubuntu just to be sure it detected the windows type sudo update grub2 see if it shows "windows loader found" if not then do a sudo fdisk -l and post the output :)

  • SORRY! I have 15.04 installed. I edited it now. But I used the same guide. I have 3 Partitions. (/, /boot and swap). I can see a 100mb Partition with folders 'boot' and 'System volume information'. – rfaenger Oct 17 '15 at 11:30
  • ok please give an output of "sudo fdisk -l" – Shantanu Shady Oct 17 '15 at 11:33

    interesting i never tried installing windows and linux in different physical storage .I know you tried all in general but try this once you said you can boot into ubuntu right ? sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update sudo apt-get install -y boot-repair && boot-repair sudo update-grub sudo grub-install /dev/sdX <-- linux /boot – Shantanu Shady Oct 17 '15 at 11:56

    im not a hardware expert , haha but i think 2 is the the limit for most boards i think at least was in intel boards and any more than that it uses a chip then ... i think that option is for that . And thanks – Shantanu Shady Oct 17 '15 at 15:02
