 Posted: Mon Mar 21, 2022 4:49 pm Post subject: Going from single MBR Gentoo 2 UEFI dual Win+grub[linux]... |
 |
|
I'm looking for the simple way to prepare my current MBR single partition (boot + root) with grub installed on the PARTITION + /home partition to be ready for duplication on the new UEFI HD.
Thus whishing to have minimal work to bind the boot process to that new partition.
Kernel is GPT ready, IIRC.
Because of minimal approach, EFI layer is missing
OpenRC with no initramfs here.
As far as Windows partition layout is concerned, I'd like to keep the factory reset...
There are 4 partitions which I plan to keep contiguous once Windows OS partition has been resized. Thus duplicated Gentoo partition would be placed as the 5th partition. Would this be a problem?
What else could be missing?
Binding ESP to Gentoo boot+root partition will be new to me...
Any link easy to follow and understand?
Thks 4 ur attention, interest & support.

I tried by best following wiki...
I order to chroot into replicated partition /dev/sda5, I first booted on MBR...
grub-install failed on missing efivars... UEFI boot required!
I had to tweak BIOS UEFI to let Gentoo Install media boot:
One configuration displayed a tree file selector to choose a file to register.
There was two kinds of registration: one with hash, can't remember the second option...
I was so lost there that I tried to tweak UEFI, by disabling Secure Boot, which kept UEFI booting active...  .
Booted without any query.
| Code: | | grub-install --efi-directory=/boot/efi |
generated | Code: | tree -L 3 /boot/efi
[/dev/sda1 mounted on /dev/sda5]
/boot/efi
├── EFI
│ ├── Boot
│ │ └── bootx64.efi
│ ├── gentoo
│ │ └── grubx64.efi
│ └── Microsoft
│ ├── Boot
│ └── Recovery
└── System Volume Information |
| Code: | | grub-mkconfig -o /boot/grub/grub.cfg |
updated /boot.grub with new items: | Code: | tree -L 1 /boot/grub
[/dev/sda6]
/boot/grub
├── grub.cfg
└── x86_64-efi |
the latter containing many *.mod files.
Besides possible missing parts Is that configuration right enough?
Anyhow booting keeps starting M$ without any prompt. 
Because with UEFI booted Gentoo install media, grub.cfg refers to | Code: | | set root='hd2,gpt5' |
.
grub.cfg doesn't contain any menu entry for M$.
Any advice?

Now verify that a "Gentoo" entry exists from:
(post it here too)
If it does, tell your mainboard firmware to boot it, either in the firmware menu or via efibootmgr to change the BootOrder |

There was some errors in the script I followed above as os-prober was NOT installed. Now fixed
grub-install has installed the two directories in /boot/grub, not grub-mkconfig as stated earlier...
Now fixed, rerun the grub-install & grub-mkconfig, as the latter returned; | Code: | Generating grub configuration file ...

Adding boot menu entry for UEFI Firmware Settings ...

So something'w wrong with os-prober here.
As a side note, M$ original EFI sda1 partition has been backuped prior to doing any change to it.
Thanks 4 ur attention, interest & support.

Doesn't your computer's BIOS allow to see or select the boot entries?
Even my not so new Dell laptop does and I never bother with efibootmgr |

After doing my homework things have improved a little here:
| Code: | efibootmgr
BootCurrent: 0001
Timeout: 2 seconds
BootOrder: 0001
Boot0000* Windows Boot Manager
Boot0001* gentoo |
Booting to M$ changes BootOrder: entry, by adding Boot0001.
Afterwards M$ will boot as soon as listed there, whatever ordering.
Onlywill reset BootOrder: as shown above, as the only configuration allowing to reboot to gentoo.
As soon as M$ has been booted, rebooting to gentoo install media is required to set ESP to allow booting to gentoo.
With the above setting, BIOS shows gentoo selected, and doesn't allow to change to M$.
As a side note os-prober requires util-linux USE=logger to detect M$ and add its entry to grub.cfg. (/etc/portage/make.conf USE=-* is the culprit for some, adequate ebuild would have avoid this nevertheless.)
Thks 4 ur attention, interest & support.

Had to run | Code: | | bcdedit /set {bootmgr} path \EFI\gentoo\grubx64.efi |
in Win10 console so that grub remains the boot loader after Win10 has been booted into.
Thks 4 ur attention, interest & support.
