[SOLVED] Grub2 not boot into GPT partition table

tiger2wander · 2011-12-23 10:34:54

Hi there,

I'm using Acer Aspire 4750. My BIOS support UEFI (I was installed Windows 8 on GPT partition) but it not give me any options in bios to force boot using UEFI method instead of old bios method.

I converted my HDD from MSDOS to GPT partition table. Tried install grub2 on it but still get message: no operating system. Currently I'm using grub2 on USB to boot up my laptop
I known there are 2 method to use grub2 with GPT:
- BIOS boot partition: created ~2MB and set it partition type to EF02 BIOS boot partition, install grub2 but not success.
- UEFI firmware: this way look better but there is no way to boot into ArchLinux using UEFI to get UEFI parameter from /proc to setup.

My questions is: how can I make Grub2 boot Arch Linux installed on GPT partition table?
I tried archlinux's wiki page for GPT & Grub2 but still no luck.

Any help will be appreciated!

Strong day!

EDITED: SOLVED with ArchBoot EFI bootable CD.

There was another thread few weeks ago on exactly this question. https://bbs.archlinux.org/viewtopic.php?id=131149

I have no trouble booting to gpt, but I am still using BIOS boot. I also use grub2. If any of my configuration files can help you, I will post them, but I never had to do anything special.

My problem is grub not loaded by BIOS after computer turn on and I have no problem with config files also since I can make it boot up from USB using grub2 installed on it.

Have you looked at this? It is where I learned to convert to gpt and setup my Linux systems to boot to it.

Can you try http://wiki.archlinux.org/index.php/Archboot iso? It boots via UEFI and also includes grub2-uefi support in its setup/installer.

Already read that link, I'm used gdisk & parted for setup gpt also.

Last time I visit kernel.org was down because of last issue & rebuilding time, look it back Up now and I will try it soon, thanks!

I tried ArchBoot iso and it work well but still don't know while I do it again by myself on running Arch and it not work. Trying to do it again with Grub2 wiki page. Hope it work well.

@tiger2wander: Can you tell me the bios vendor of the bios in your Acer laptop? Is it AMI, Phoenix or Insyde? Right now AMI Aptio UEFI does not seem to create any issue with BIOS-GPT boot or with UEFI boot with efiboootmgr. It also allows launching UEFI Shell is required. Phoenix SecureCore Tiano UEFI does not seem to allow booting in BIOS-GPT mode and in UEFI mode does not work with efiboomgr, and no access to UEFI Shell. No idea about Insyde H2O UEFI.

Is your Efi partition vfat? This is important and Archboot won't do this automatically. This was the reason why I failed to boot in Uefi mode. Furthermore I've read somewhere that it is important to perform the installation in Uefi mode. So make sure that your installation stick is booted accordingly.

@the.ridikulus.rat: this is my BIOS firm information:

@tobsen: yes, my Efi partition is vfat and I've successfully installed GRUB2 UEFI on GPT partition table. FYI, my partition tables currently:
