Missing grub entry to new install of F38

[mario60]

Hi

i am having a number of issues with an install of F38

First and foremost I do not have an entry to F38 on my grub menu.
To get to the login page to F38, I need to push F11 at booting, and then to select the hard disk which I know hosts F38.

I tried

$ sudo grub2-mkconfig -o /etc/grub2.cfg
Generating grub configuration file ...
Adding boot menu entry for UEFI Firmware Settings ...
done

and

$ sudo grub2-mkconfig -o /etc/grub2-efi.cfg
Generating grub configuration file ...
Adding boot menu entry for UEFI Firmware Settings ...
done

but to no avail.

Also

/boot/efi/EFI/fedora/grub.cfg is:

search --no-floppy --fs-uuid --set=dev 3e(snip)
set prefix=($dev)/grub2

export $prefix
configfile $prefix/grub.cfg

Is it ok?

I am not sure how to interpret that grubby shows all the correct entries:

/boot/efi/EFI/fedora/grub.cfg is:

search --no-floppy --fs-uuid --set=dev 3e(snip)
set prefix=($dev)/grub2

export $prefix

Is it ok?

Can’t tell due to the snip.

The uuid has to match up with the uuid you see when running lsblk -fp.

@vekruse

The uuid has to match up with the uuid you see when running lsblk -fp.

yes, here you have it:

export $prefix

They match, don’t they?
Also, am I missing something, don’t I need a swap partition?
Also, I don’t see any menuentry within my grub.cfg as described by Red Hat

Hey there, It looks like you never got back to us on the Failed to Upgrade F36 to F37 post , where we were going to help you fix the OS, here was your last comment :

@mario60

I’ll be back when I am ready
Thanks Cheers

Then you started a new thread, I am unable to install F38 , While you did leave some interesting tips about your computer set up here :

@mario60

EDIT: Eventually I succeeded to install F38 from the liveUSB.
I still miss a Grub entry to F38. At booting, I need to select F11, then the hard disk which I know hosts F38.

Are you trying to Dual Boot the machine with Windows or another OS? If not, What is the Boot Order in your BIOS ? If you have it set up to start something other that the HDD that Fedora is on you will get a screen prompting you for it.

Some BIOS allow you to choose the Boot Order like ( CD, Floppy, PXE or USB or another device. It’s usually 3 options and you need to assure you are setting it to the HDD you have Fedora On)

[mario60]

@hamrheadcorvette

Are you trying to Dual Boot the machine with Windows or another OS?

Actually, I have indeed a (out of business) second hd, with a old Debian 8 I have never used.

Disk /dev/sdb: 232.89 GiB, 250059350016 bytes, 488397168 sectors
Disk model: Samsung SSD 850 
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

Disklabel type: gpt

my present grb menu (debian is not working, underlying disk neither)

options for boot device

third entry gets into the working F38. HP SDD disk is relatively new.

I am trying to understand the configuration, So you have 2 HDD’s and 1 has Debian, 1 has Fedora ? If not, when you can please provide us the answer the the question below

@hamrheadcorvette

What is the Boot Order in your BIOS ? If you have it set up to start something other that the HDD that Fedora is on you will get a screen prompting you for it.

[mario60]

hammerhead corvette, please see pictures in my edited previous post. Is that enough info to understand what is going on?

[hamrheadcorvette (hammerhead corvette)]

@mario60

Is that enough info to understand what is going on?

Yup ! just as I suspected. . . Very clearly, Your BIOS is telling you "What Should I Boot from ??? " This is normal behaviour when there are several boot entries, The questions remain :

• Do you have an active Debian install you would like to keep?
• if Fedora is the only OS you want to keep, We need to clear those boot entries.

[mario60]

@hamrheadcorvette

• Do you have an active Debian install you would like to keep?
• if Fedora is the only OS you want to keep, We need to clear those boot entries.

No, I have never used it (actually, I think it was even a double boot with an older Fedora, wIth the new disk, I just kept Fedora).
Yes, for the time being, I just need Fedora.

How do I clear those boot entries? (and, so to speak, where are they?)

Thanks

Can you provide the results of ls /boot/loader/entries/

@hamrheadcorvette

Can you provide the results of ls /boot/loader/entries/

yep

You can use efibootmgr to modify the booting.
You are currently booted from entry 0007 so we can eliminate the unnecessary entries, especially the one that is shown as first in boot order.
One at a time try this.
sudo efibootmgr -B -b 0001
Then repeat that for the entries 0002, 0003, 0004, & 0005

You also can set a default boot order with sudo efibootmgr -o 0007,0008 which should set it so only those two entries would be in the boot order list.

Use man efibootmgr or efibootmgr --help to get more information on what that command may be able to do for you.

Hi

nope!
I may set them in a different order

[root@fedora mario]#  efibootmgr -o 0007,0008,0001,0002,0003,0004,0005

BootCurrent: 0007
Timeout: 1 seconds
BootOrder: 0007,0008,0001,0002,0003,0004,0005

but it is not really saved. When i reboot, and get back to check it, it is as before

EDIT:
some good news!
I tried efibootmgr -B -b 0001, efibootmgr -B -b 0003, and efibootmgr -B -b 0004, and indeed something got fixed.
At reboot, I got into the F38 login page (good new!); I was not shown any grub menu (why not?)
and something had been generated anew:

I am not sure to understand what is going on, and what does what.
Your tutoring is welcome.

At reboot, I got into the F38 login page (good new!); I was not shown any grub menu (why not?)
and something had been generated anew:

By default the grub boot menu is hidden, but if you hold the shift key down while booting it should show.

Are you still looking to remove these two enteies?

I see, I’ll try and report.
What I see now is that to push either F11 or DEL while booting doesn’t let me enter BIOS any more, is it ok?

EDIT:

@vekruse

hold the shift key down

yes, it works, very nice indeed!

(How/where could I have learned about it??)
