[EN] EFI install
« on: 2016/01/23, 21:43:26 »
I made the efi boot partition with gdisk. The installer recognizes it but I'm not sure if I mount  the boot partion (sda1) even though it recognizes it below as efi. When installing the boot manager I'm not sure where to install it to a)mbr b) partition c)sda .

Note: I have a new HP laptop that has an i3 processor and 8gb of ram. All other distros I've tried have been really slow on it accept for the KDE paintitblack edition. It boots fast, applications launch fast, and websites load faster. I really hope I can get help to install this. Thanks.

If your HP laptop is new, didn't it come with windows?  If so, it shouldn't have been necessary to create the /boot/efi folder with gdisk.  It would have been created when HP installed windows onto it.  UEFI has one /boot/efi folder for all operating systems installed onto it.

I'm sorry, but, the last siduction install onto UEFI I did was a few years ago.  So, I haven't looked at the siduction installers ability to install on UEFI in a while.  Although I do remember being able to point the installer to /boot/efi during the installation, and, was able to complete the installation successfully.  FYI - One doesn't use mbr at all on a UEFI enabled computer.  Could you be having trouble because you wiped windows off of the disk and are starting fresh?

There are actually 3 Boot Managers/pointers in a UEFI box.  The first one is contained in the UEFI bios (yeah, I know it's not really called a bios, but, for lack of a better word), this is what you see when first booting in UEFI mode.  The second Boot Manager/pointer is on the disk in /boot/efi/efi.  This is where UEFI points to the distro/OS chosen at boot up time.  The third Boot Manager will be Grub.  So, one does not use Grub to chose the distro on a multi boot UEFI machine, one uses the UEFI bios for that during start up.  As far as where the Boot Manager (grub) gets installed, it gets installed to the root partition.

A few years ago, I started this thread: http://forum.siduction.org/index.php?topic=4254.msg37957#msg37957 to help with installing to UEFI.  I'm sure it may be out of date a bit, but, the part that explains what happens when using the siduction installer may be helpful.  The comments in that thread also have useful links and comments that may also be helpful. 

Hope this helped.  If not, provide more info, and you'll get more specific answers.

BTW - If anyone see's errata in this post, please comment.  Except for my main machine, all my other boxes still use mbr, and, the siduction installer works great on them.  Unfortunately, I haven't updated the UEFI box since July, and, may have to do a fresh installation, so, I'm also curious about the state of the installer when using a UEFI enabled machine.

Yes I have completely removed windows.

I understand what you mean by three loaders. I tried this time not to mount the boot partition (efi) because the installer said that it's mounted. I then installed grub to the root partition. I can see that something installed because after I boot I see efi/grub then debian, but nothing to load...

I have installed other distros without windows being on this so I don't think that's the problem. I'm sure I'm not doing something right during the install. I've never manually installed to uefi, I've always used an auto installer.

@ashley: efi-partition != boot-partition

I know it is hard, but you should not stuck in the old terms - that make understanding efi more easy. EFI in short:
1.) We recommend a  hard disk with GPT
2.) Create a EFI partition (with the correct type), format the partition with fat32
3.) Start you system from stick or dvd with efi enabled in the bios, you will notice the fugly grub menu instead of syslinux
4.) Start the installer, select your root partition, add the efi-partition and set the mountpoint to /boot/efi i think
5.) Start the installation - the option where to install grub don't matters, don't be afraid of the grub install messages
6.) if the installation is done, restart the system, a system with efi start should come up.

If anything fails, come to our IRC channel, we can sort this out.
