I am thinking about to install 15.04 to my PC which has the following specifications:

Previously I have installed 14.04 on this system in UEFI mode and the entry of Ubuntu is still shown in UEFI. I know I can remove that entry with efibootmgr but I am afraid to use that because of the unknown (maybe fatal) consequences.

My question:

  • This install method is correct for my system?

Thanks for your kindness!

UPDATE:

  • Install it the same way as you installed 14.04. But it is better to leave 14.04 LTS as it is. And please ask one question at a time.

  • Thank you for your answer but it was a long ago I have installed 14.04 so unfortunately I can't remember some steps. I would like to please you if I miss something please let me know that. As far as I remember I have done the following: 1. created an uefi usb drive on windows (at that time on 8.1, probably with rufus, so i have selected gpt in that)

A short how to how I installed Ubuntu on my system:

  1. Created an UEFI GPT pendrive with Rufus

  2. Since I was using Windows 10 I have disabled “Fast Startup”, checked BitLocker is off and turned off hibernation (powercfg /h off).

  3. Disabled Fastboot in UEFI
  4. Also disabled Secure Boot (Switched to “Other OS”)
  5. Booted from UEFI pendrive.
  6. Created an 1024MB fat32 primary partition (with the label “EFI”) with a free space of 1MiB preceding
  7. I have 16GB of RAM so I created a 16384MB swap partition with linux-swap file system.
  8. The rest (without the 10-15% provisioning space) went for / (root) with ext4.
  9. Agreed the UEFI install warning
  10. Then the install method was the same like on a BIOS machine.
  11. I have installed fglrx (fglrx-updates) for my Radeon R9 270X

This step is necessary if you have an ASUS Xonar sound card!

  1. Turned volume to maximum in alsamixer for my Xonar DS in Master Front

P.S.: Alignment and TRIM is automatically enabled on newer Samsung SSDs.
