I did exactly the same thing (gave my system partition the label 'EFI') and couldn't boot. I would never have suspected that as the issue.

Is it a simple matter of (apt-get) installing the EFI version of grub. The last time I tried (with grub-efi-amd64) I got as far as the grub rescue prompt. I'm now back to grub-pc. I couldn’t agree more.

Create a small GPT partition, of type “EFI System Partition” (this is “set boot on” with parted). It must be able to hold GRUB's core image that weights 30 kiB; I use 1 MiB to be at ease. 2. Format it as FAT (12, 16 or 32 bits, it does not matter so leave the automatic choice of mkdosfs) and, if you want to label it, choose another name than “EFI”! 3. Mount it under /boot/efi (and make that permanent by adding an entry to your fstab). 4. Install grub-efi-amd64. 5. Run install-grub: this will generate the appropriate core image (using grub-mkimage), put it in the appropriate place on your EFI partition, and add a “debian” entry to the EFI boot manager menu, pointing to that GRUB code image (using efibootmgr). 6. Run update-grub: this will generate the appropriate GRUB configuration file, which is important because your old one was adapted for GRUB PC, not for GRUB EFI which uses different modules, for instance to get a graphical output. When you get the GRUB rescue prompt, it means that GRUB's core was loaded, but unable to access to its modules (stored in your regular /boot/grub) which are needed to get a normal prompt. There can be several reasons for that, for instance: if your mother board does not detect the EFI partition (see the last section of my post), it will boot in BIOS mode, and it may then find your old GRUB PC, which will not find its modules since you have replaced them with GRUB EFI's ones!

I don't know how about A1000 (1985) :] Thu, 18 Aug 2011 18:56:00 +0000 Camelek https://tanguy.ortolo.eu/blog/article22/efi-boot/#c1313657651-1 https://tanguy.ortolo.eu/blog/article22/efi-boot/#c1313657651-1 I was referring to the GUIs.

Corrected, thank you. 2. That would be great indeed. I shall contact you to get more information, like: where to buy flash chips (I already saw it was socketed, by the way).

Indeed, AMI's WinBIOS did this in 1994. Thu, 18 Aug 2011 02:05:00 +0000 Ben Hutchings
