 Posted: Tue Jan 01, 2013 3:43 pm Post subject: [SOLVED] UEFI, GPT and GRUB2 boot problems |
 |
|
Hello, I'm trying to get Gentoo to work on my PC but I'm having severe problems due to the countless wikis/documentations not complementing each other.
partitions:
| Code: | 1 32MB Linux filesystem ext4 /boot
2 32MB EFI System vfat /boot/efi
3 rest Linux filesystem ext4 / |
.config: http://bpaste.net/show/67570/
* EFI modules included, according to wiki
* loadable module support + initramfs disabled
* ext4 included
hardware:
- intel CPU (ivy bridge), asrock Z77 mainboard
installation process:
1. create partitions
2. stage3/portage download and extract
3. create kernel
4. install software (dhcpcd, syslog-ng...)
5. grub2, efibootmgr
* mount /boot and /boot/efi
* grub2-install --target=x86_64-efi
* efibootmgr -v:
| Code: | BootCurrent: 0000
Timeout: 1 seconds
BootOrder: 0000,0003,0001,0002
Boot0000* gentoo
Boot0001* Hard Drive
Boot0002* USB
Boot0003* UEFI: USB Flash Disk |
I'm using systemrescuecd (gentoo based live CD) with EFI VARS kernel.
After rebooting I get "Reboot and Select proper Boot device or Insert Boot Media ins elected Boot device and press a key".

A few things I think you should try:
- The EFI partition has to be over 200MB (mine is 500MB, a bit overkill, but I read in several places that it has to be over 200MB).
- You don't need a dedicated /boot partition, but then again, this shouldn't affect you. To give you an idea, my kernels and initramfs are in my root partition and grub2 can load them perfectly. Again, having this shouldn't hurt you.
- I didn't have much luck with efibootmgr, so I copied my grub.efi to /boot/EFI/BOOT/BOOTX64.EFI (assuming that your EFI partition is mounted in /boot), in this way, your firmware's boot manager should find that file to boot when you select the device where your EFI partition is. This tip is probably the most important one  If you find that grub2 boots in this way, then efibootmgr didn't help you setting up the custom location of grub.efi. I didn't personally bother trying to get this to work as I know that your mileage certainly varies depending on what system you are using.
Good luck! |

Hi, did you compile Grub2 with the uefi stuff ?
Do you have this inside your /etc/portage/make.conf :
| Code: |
GRUB_PLATFORMS="pc efi-64"

Good point, although I assume that if this works:
| Code: |
grub2-install --target=x86_64-efi
|
then, you compiled grub2 correctly. |

Nobody seems to be sure, every wiki/documentation states another numer, the german gentoo translation uses 32MB (point 4b): http://www.gentoo.de/doc/de/handbook/handbook-ia64.xml?part=1&chap=4&style=printable

Do you want me to copy /boot/grub2/x86_x64-efi/grub.efi to /boot/efi/boot/bootx64.efi?
@d2racing: Yes sir, GRUB_PLATFORMS="x86_x86-efi" is in my make.conf an grub has been compiled with it.
side note: I tried funtoo before and its grub2/gpt/efi wrapper works out of the box, though I never managed to get Gentoo running :/ |

I think a dedicated /boot partition is a good idea, since it increases flexibility. I don't want to belabor this point, though, since it's peripheral to the real problem....
| Quote: | | - I didn't have much luck with efibootmgr, so I copied my grub.efi to /boot/EFI/BOOT/BOOTX64.EFI (assuming that your EFI partition is mounted in /boot), |
This is certainly worth trying. There are some badly broken EFI implementations that forget their NVRAM entries or ignore entries that don't fit certain patterns. (The efibootmgr utility adjusts these NVRAM entries.)
If you don't immediately try moving GRUB as gabrielg suggests, please post the output of "efibootmgr -v" (note the "-v"). This will tell us to what files your NVRAM entries point, which is critically important information, given your problem.
The EFI documentation is silent on the question of the size of the ESP; however, the EFI spec is quite explicit that the ESP must use FAT32. (OTOH, FAT16 usually works, and sometimes it works better than FAT32, in practice. Some firmware implementations choke on FAT16, though, as does the Windows 7 installer. On balance, I'd say that FAT32 is the safer choice.) The Linux mkdosfs utility creates FAT32 by default only on partitions over about 512MiB (I don't think it's exactly that, but it's something similar), and it refuses to create FAT32 on partitions smaller than a certain value. I'm not sure if inch's 32MiB is below that value. Microsoft creates a 100MiB ESP by default, Apple creates a 200MiB ESP by default, and Linux distributions are all over the map. IMHO, 100-500MiB is a reasonable range, with my preference being 200-500MiB.
Incidentally, it's possible to mount your ESP at /boot. This is a bit unusual, but it works, and it cleanly solves a few minor problems.
One more point: IMHO, GRUB 2 is the worst of the available EFI boot loaders for Linux. For a Linux-only installation, particularly if the user is reasonably Linux-savvy (as most Gentoo users are) ELILO is much better -- it's simple and reliable, although it lacks configuration scripts to modify the setup whenever you add a kernel. It can benefit from mounting the ESP at /boot. Another good option is to use the EFI stub loader (included in 3.3.0 and later kernels) with a boot manager such as my rEFInd or gummiboot. rEFInd can be particularly handy, since it can load EFI filesystem drivers to read a kernel from an ext2/3/4fs or ReiserFS partition and it can auto-scan for new kernels, so you needn't muck with its configuration when you upgrade your kernel. All this said, based on the symptoms, I don't think the problem that inch is experiencing are with GRUB per se; I think that the firmware isn't finding GRUB because its NVRAM entry is wrong or because the EFI has a bad bug that's causing it to ignore the NVRAM entry. |

Yes - that's exactly what I mean, then use your Firmware's boot manager to boot from your hard drive where your EFI partition is.
srs5694 kindly provided a detailed explanation of the state of EFI these days.
I am not familiar with funtoo, I can tell you that Fedora installs no problem on an EFI implementation (including the broken ones that Apple used in 32bit firmwares with 64bit CPU's) and that I used Fedora's approach to install Gentoo in one of my boxes.
I believe that you will fix your immediate booting problem by placing the grub.efi as I said before - you can later experiment with efibootmgr and post any findings if you like (I will certainly find them useful ).
For reference, my latest EFI experience comes from a Lenovo Thinkpad X230, and the only reason I use Grub 2 is that it can decrypt a LUKS partition. I found it painful to configure, but eventually got it working, by looking for information everywhere. I can certainly help further if you choose to continue with Grub 2 and bump into issues that I know of. |

I tried copying the file and to boot from it, without success. However, I seem to be doing something fundamentally wrong because I don't get anywhere near GRUB2, it just gives me the message to insert a boot media.
To detected possible errors, I try to describe what I'm doing:
I'm booting from USB, choosing "UEFI: usb media" in the UEFI boot menu. Then I proceed with the install. After this step, I choose "gentoo" in the boot menu and get the message that there is no proper boot device.
Also my directorys seem to be wrong, grub2 is in /boot and not in /boot/efi/grub2 as it is supposed to be.
So far Grub2 is a pain in the ass and I'm right before quitting. |

If you've got a CD-R, try downloading the CD image version of rEFInd. If not, download the regular zip file, unpack it, and prepare a bootable USB flash drive version of it, as described on the rEFInd Web page. Either way, try booting with it and see what the rEFInd menu gives as options. With any luck you'll be able to boot. If you can boot in this way, post back the results of the following three commands (you'll need root access for the third, and perhaps for the second):
| Code: |
df /boot/efi
find /boot -name "*.efi"
efibootmgr -v
|

Based on your earlier posts, it looks like your ESP is mounted at /boot/efi. With that mount point, GRUB might be stored in /boot/efi/EFI/grub2 or /boot/efi/EFI/gentoo, but /boot/efi/grub2 would be an improper location. Depending on how it was built, GRUB might put all its modules, configuration files, and other support files on the ESP or it might store some of them in /boot/grub2. Thus, it's not clear that anything is amiss regarding file placement.
| Quote: | | So far Grub2 is a pain in the ass and I'm right before quitting. |
I can't disagree. GRUB 2 works tolerably well on Fedora, Ubuntu, and other major distributions because GRUB experts carefully configure it, including elaborate scripts to scan for OSes and add entries to the GRUB configuration file. When somebody with lesser skill tries to configure it from scratch or in an unusual way, it tends to come tumbling down. That's why I suggested trying rEFInd, gummiboot, or ELILO -- they're all much simpler to configure than GRUB 2. |

rEFInd got me up and running rather painlessly. Just saying....

As I just recently did this on a Asrock h77 board, thus with almost identical BIOS support:
Use EFIstub, by far the easiest option. Just recompile the kernel with EFI stub support and compile also your kernel command line in.
Check with gdisk that your hd is GPT and has the correct EFI partition type (EF00).
Append .efi to kernel and use efibootmgr and point it directly to your kernel, which you can conveniently put directly under your EFI basedir. |

Without reading your post, I got Gentoo up and running with an EFI Stub kernel 
Thanks guys, works flawlessly and configuration (so to say) is a piece of cake. |
