Well, I thought I'd post a followup saying that it worked out pretty well.

After finishing the Ubuntu 13.04 installation, it didn't boot linux -- just booted Windows 8 as expected.

I had followed all the instructions and moved EFI/Microsoft/bootmgfw.efi away and at that point, it booted linux, but I couldn't get it to run rEFInd. I didn't worry about getting rid of EFI/redhat/grub.efi because I wasn't using redhat nor did I have an EFI/redhat directory.

However, after a lot of flailing, I discovered that it first tried to boot EFI/Microsoft/bootmgfw.efi, then it tried to boot EFI/ubuntu/<something> where something was either grubx64.efi or shimx64.efi. I'm not sure which because I discovered this by moving EFI/ubuntu to EFI/ubuntu.old and then it started booting rEFInd. I guess that luchnkov's Redhat installation added the redhat path to the list while my Ubuntu installation added the ubuntu path to the list.

This last part is curious, because I had trouble using efibootmgr to modify the path. I found that most of the time when I ran efibootmgr -c ..., it did nothing. Then I found there was an error in the dmesg log output saying:

efivars: set_variable() failed: status=8000000000000009

for each time I ran efibootmgr -c. This is likely related to this bug:

https://bugs.launchpad.net/ubuntu/+s...x/+bug/1167622

which will presumably be fixed soon, but not yet.

In any case, after moving the EFI/ubuntu directory out of the way, rEFInd would start and I could choose between booting Ubuntu and Win8.

BTW, I turned Secure Boot off in the BIOS to make things easier.

Thanks for everyone's experience in this thread.

Hi Team,
I found this thread almost addressing my issue, but still need your help.

I have Sony Vaio with H2Bios (InsydeH20 Setup Utility Rev.3.7 - looks as the most current one) running Win7.
My goal is to install Ubuntu 16.04 next to Win7. Here is what I did:

1. freed up about 200gb for Ubuntu partition. Here is how disk partitions look after that:



2. Built bootable USB drive with Ubuntu 16.06
- using program Rufus 2.18
- chose MBR partition scheme for UEFI (for Partition scheme and target system type)

3. Changed boot sequence to start from External device first, booted from USB and install Ubuntu on the HD
4. verified a set of partitions after that

ubuntu@ubuntu:~$ sudo efibootmgr
BootCurrent: 0000
Timeout: 5 seconds
BootOrder: 0000,0002
Boot0000* EFI USB Device
Boot0002* Windows Boot Manager
ubuntu@ubuntu:~$

5. Installed Ubuntu on HD into /dev/sda1 (as found in some recommended articles)

ubuntu@ubuntu:~$ sudo efibootmgr
BootCurrent: 0000
Timeout: 5 seconds
BootOrder: 0001,0000,0002
Boot0000* EFI USB Device
Boot0002* Windows Boot Manager
ubuntu@ubuntu:~$

I do not see any GRUB partitions there!!! What is the partition related to 0001 ?

Should I put Ubuntu boot loader into /dev/sda3 - where Windows Boot is?

-------------
In your answers I see some recommendation like "I installed/booted the EFI shell and proved that I can boot Windows by calling bootmgfw.efi directly from the shell"

Unfortunately, I cannot understand what it is.
All nice stuff written by luchnkov (on 07-18-12 08:54 PM) and others are hard for me to understand

Can someone put it into step-by-step instructions for me and others?

This will be greatly appreciated. Thanks in advance.
