hello I did the instructions for efi booting and doing alongside windows. I have acer r3 131t 32gb model with 2gb ram I have a 64db sd card and installed there.

it has windows 10 installed (not so bad for $250) I followed the instructions without doing a windows restore disk because there is no data partition on a 32gb disk!

I got as far as the boot repair but it still did not "repair" it. It did not instruct me to paste anything. However I pasted the code from the website below which is also in the "linux user" web page instructions. bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi

The uploaded bootrepair is on http://paste.ubuntu.com/14348507/

So I cannot boot into ubuntu 15.10 It luckily still boots into windows.

I did not see any way to delay the boot time in the bios. I set the boot order to the main disk first. There is not a choice to boot from sd, but something is surely in the efi partition for ubuntu. I can see it.

any suggestions. Please email me in addition to posting here(I am a monk in myanmar). bksubhuti-atthegma1l (figure it out) will edit this out later.

Just a small complaint: Why can't the install program do this right and why are there all of these help guides? I am technical and patient.. but how can Ubuntu spread with things like this. The install program should have a help guide in it. If you need to do something else... then tell them to do it.

I was able to fix this problem. I am not sure 100% the exact cause because I ran boot repair advanced options but that never worked until I did things below:

I read a little bit of the boot repair link I posted and the first comment response helped something clicked after fooling with the bios. By lucky guess I saw the enable trusted uefi and clicked on it. Through several clicks..I got to the Ubuntu boot file. There were several (other than efi backups) probably from many boot repairs. I selected all of them. That was cool but it still did not get grub to load. However I got the grub to boot by the f12 choose boot. 3 choices showed up on the menu this time instead of just Windows. The third one labeled "1 Yes" worked. Then I went back to the f2 for general bios and saw "EFI File Boot 1: Yes" and another with "0" instead of "1" at the bottom of the boot order. These were familiar new options which I now could see for the f12. (Before enabling trusted efi, these options were not there) I may have disabled tpm state too (whatever that is). It is disabled now and may have been enabled before. That might also be a cause.

As far as I know through trial and error: 0yes means boot the operating system on mmblk0 (Windows) 1yes means the other disk on mmcblk1 (Ubuntu). But it could just be the number of boot filled I created with boot repair. However the "0" file does not boot grub.

Moving "EFI File Boot 1: Yes" to the top of the boot order makes grub boot automatically. So my work has just begun. Thanks for helping.

So now I have Ubuntu 15.10 fully installed on my sd (no casper stuff). It is much better than a live USB. I just cannot use my SD slot which is no problem. Ubuntu idles on ½ gb of my 2gb of memory.

In retrospect due to what I write above, I am not 100% sure grub is on mmblk0p1 (efi) as I said before. When Grub first did not work, I installed again choosing "something else" and maybe missed the boot install option (though I doubt it and I did a "something else" installation twice to make sure.
