11.04 UEFI problems

[Avidanborisov]

Hi everyone
I had this thread on Natty Narwhal Testing and Discussion forums. Starting from page 5 I had problems with UEFI booting, you can read all of the thread from there. But the forum was closed one hour ago leaving no one to answer the latest comment:

hi
Everything worked pretty great, just my ubuntu did recently an upgrade, and I forgot about everything. I rebooted and GRUB was broken (I got GRUB rescue).
Good I backed up my EFI folder, but I tried to replace it and it just didn't work, I skipped to Windows bootloader because it was the second entry in the UEFI.
Is there any way to fix it?

So... is there any way to fix this?

You are lucky, most people (including me) can't even get it to install properly on UEFI. Good luck in getting an answer.

Avianborisov could you please in a step by step guide explain how you got grub2 efi to see windows 7? I am having the same issue as you and quite frankly don't have the knowledge of ubuntu you do because I read those post in the other thread and entirely confused about what you actually did. Thanks in advance.

Well this is what I did to make it work:

1. installed ubuntu and then after I ran updates I didn't restart but went to synaptic, uninstalled grub-pc and installed grub-efi.
2. Since GRUB overwrote everything in the EFI partition I entered my Windows 7 installation disc and chose to repair startup problems which returned the efi bootloader for windows.
3. Compiled GRUB2 from source using this guide -
http://grub.enbug.org/TestingOnUEFI
which created the folder "grub" in the EFI partition. So I deleted the ubuntu folder in the EFI partition and renamed grub folder to ubuntu. then since /boot/grub isn't useful as it doesn't to anything to the EFI folder and update-grub command doesn't work I copied all the files from /boot/grub to ubuntu folder in the EFI partition. I didn't overwrite anything though.
4. added this:

menuentry "Windows 7" {
  search --file --no-floppy --set=root /efi/Microsoft/Boot/bootmgfw.efi
  chainloader (${root})/efi/Microsoft/Boot/bootmgfw.efi
}

to the 40_custom file and ran this command:

sudo update-grub

5. Everything worked till the update..

Avidanborisov do you know another link with the same info because I am unable to go to that specific link and searching Google only ends up trying to redirect me there. Thanks in advance again.
