I had installed Ubuntu 15.04 in the past alongside Windows by disabling secure boot and UEFI. Then I got dissatisfied by Ubuntu performance. I decided to remove Ubuntu, deleted most of the stuff. After that, whenever I went to boot menu, it still had two options below Windows, of Ubuntu hdd2 and Ubuntu hdd3. I didn't bother about it.

After the release of Ubuntu 16.04, I want to install Ubuntu again. After successful installation of Ubuntu, it says restart. When I restart, then by default Windows loads, so I have to go to the boot menu and select Ubuntu hdd2 or Ubuntu hdd3. Then it shows me grub 2.02 console.

Methods I have tried:

  • disabling all the secure boot stuff again
  • using easeus software
  • trying various Linux commands on the grub console screen.

Also, I didn't get the option while installation in Ubuntu to "install alongside windows" so I had to use those partition.

Now I really want to install Ubuntu. Help! :)

**edit it worked like a charm , look at PCP answer below :), 16.04 is looking amazing....better than windows 8 and 10 **

  1. Go to your windows 7/8/10 machine.
  2. Un-Allocate some space e.g 100 GB by deleting some partition.
  3. Now reboot your system with bootable usb/CD of ubuntu 16.04 LTS.

It will automatically detect the unallocated space and will get installed their without disturbing your other systems.

Note: Ubuntu 16.04 Beta release contains may bugs. I will advice to install security update daily.

If you want to install windows and ubuntu, you can use bellow way

windows in UEFI

and

ubuntu in legacy

then after, you want log in windows go to selection option in BIOS and you select UEFI for windows login and you selected legacy for ubuntu login then after u can use that way.

Important :- most using os must be install as UEFI.

Have you tried disabling fastboot (if enabled) ? It's under your power saving settings in control panel Win7. Win10, it's buried in with screensaver settings I believe. I used to have dual booting issues, disabling fast boot option corrected the issue. Just a thought.
