I think I heard about Gentoo first about 8 years ago, and maybe I should have had time to check it out before. I have used linux since 2006\/2007, starting off with Ubuntu, since it was easy, and then switching to Debian around 2010-2011. Since Debian is moving to systemd, and I am not convinced about that, I should try out some other distributions. Time has come to test Gentoo. I tried installing it to a virtual machine on my workstation first, and I think I will be able to pull this off.<\/p>\n
Hardware:All of my hardware is from 2011 or older.<\/p>\n
CPU:Intel Core i5 2500K
\nMotherboard:Asus P8H61-M EVO<\/p>\n
I will install it on a spare hard-drive, and will probably let it live parallel to my main Debian Jessie system, not even configuring the main boot-loader to have an option to start Gentoo, instead be forced to manually change the boot device to boot from the Gentoo disk. We will see what I am capable of doing before growing tired.<\/p>\n

\nNow, it is time to download the stage3-file. I downloaded the stage3-amd64-20161020.tar.bz2<\/code> file, since my installation medium was downloaded from here. I think it might be safest to not mix them, which means my installation medium will be useless in a couple of weeks.<\/p>\nMAKEOPTS=\"-j5\"<\/code>, since I have 4 CPU-cores.<\/p>\n\/default\/linux\/amd64\/13.0\/desktop<\/code>.<\/p>\nEFI stub support<\/code> under Processor type and features -----><\/code> and USB Serial Converter Support -----><\/code> in Device Drivers ----> \/ USB Support ----><\/code> since I got a USB serial converter I would like to use (maybe this is unimportant).<\/p>\n

Then I installed cron.<\/p>\ne2fsprogs<\/code> and dosfstools<\/code>.<\/p>\nmake.conf<\/code> to have EFI support, and then installed grub2 boot loader.<\/p>\n
\nNow it is time to reboot and see if it works.
\nWhen umounting the \/mnt\/gentoo\/sys file system, it complained that it couldn’t. Strange.
\nBooting doesn’t seem to work =(.
\nMaybe my motherboard doesn’t support UEFI after all, but it says so in the specifications. Trying to “Launch EFI Shell from filesystem device” when having sdc as boot device reports “Not found”. So maybe something with the installation has failed. Maybe the hard drive has to be connected to one of the first SATA ports? No, it is not that.
\nSo investigate further tomorrow.
\nSo, continuing. I have booted the live cd again, and chrooted into my install. This time, I will verify the files generated by grub. First, I read the “Important” note in the handbook – “Make sure \/boot is mounted before running the grub-install command”. I checked, and my \/boot wasn’t mounted in my chrooted system, even though I did mount it before chrooting. Strange.
\nRunning the grub install command for efi:
\ngrub-install --target=x86_64-efi --efi-directory=\/boot<\/code>
\nI got the error message:
\nInstalling for x86_64-efi platform.
\nefibootmgr: EFI variables are not supported on this system.
\nefibootmgr: EFI variables are not supported on this system.
\nInstallation finished. No error reported. <\/code>
\nSearching for this term lead to this thread<\/a>. I think my cd was not started in EFI-mode, because it is the minimal install cd. The fallback instructions in the second answer says you should copy the grubx64.efi file from \/boot\/efi, but my installation only has a \/boot\/EFI folder, so I will test if it boots, then resort to other measures listed there.
\nWhen I the exit the chroot, I notice that the boot partition has two entries in mount. Strange. Unmounting \/boot does remove one entry. One entry is still listed. Trying to unmount again fails – Strange.
\nBooting didn’t work. So, now I will copy the grubx64.efi file to the location specified in the forum answer. That didn’t work either.
\nI think I will fall back to normal mbr next time I try it.
\nI have created a systemrescuecd(download<\/a>, and booted it in EFI-mode.
\nI tried the instructions in this link<\/a>, but the efivars file system type wasn’t found.
\nI exited the chroot, looked at the kernel modules, then chrooted back again, and this time, the command
\ngrub-install --target=x86_64-efi --efi-directory=\/boot<\/code>
\nworked. Strange. Now reboot and try it. It didn’t work. Next reboot, without choosing boot medium, it booted. Hooray. Maybe because choosing the hard drive as boot medium will boot non UEFI. I should choose the name of OS instead (It showed up as “Gentoo” in the menu).
\nNext is to install desktop environment etc. I will create a new post for that part.
\nBut, no network card seems to be detected. Maybe I need to enable some modules in the kernel configuration.
\nSo, reconfigure the kernel then.
\nI checked my network interfaces before on my running debian system, and found out that I have a Realtek RTL8111\/8168B as a wired ethernet interface. So I enabled
\nDevice Drivers -> Network device support -> Ethernet driver support<\/code> “Realtek devices” in the kernel (*) and “Realtek 8169 gigabit ethernet support” in the kernel (*).
\nI have also a wireless interface which is a Atheros Wireless 802.11n. So I enabled Device Drivers -> Network device support -> Wireless LAN -> Atheros Wireless Cards<\/code> and enabled the Atheros 802.11n wireless card support<\/code> with all the sub options.
\nThat did the trick for the wired ethernet at least. Will try the wireless when I have a desktop to start.<\/p>\n","protected":false},"excerpt":{"rendered":"
