reboot, if your able to boot into endea, run

Code:

sudo update-grub

Hii, your method is something new.
I would love to try that out.
Before that i have tried the commands in my other endea kde laptop.
among the 3 commands.. only 1 exist.

command not found:
update-grub
grub-pc

this package is available
grub-install

so, should i install "update-grub and grub-pc" before hand ?

In an earlier post, you indicated there was no option to disable EFI, pretty common. You also said there was an option to turn CSM on or off, make sure it is on. Your system is booting from the install media in EFI mode and you should be booting in Legacy mode with CSM enabled/on

In your last post you indicate several commands fail. I've never hears of the Linux OS you are trying to use and can't find it online but some of the commands such as update-grub are basically used on Ubuntu and several other systems. The standard command and the script that is actually run from 'update-grub' is grub-mkconfig. Look in your /boot/grub directory to see if you have a directory named i386-pc. If you don't, just copy it there from /usr/lib/grub directory and run grub-install as suggested again.

If whatever OS you are actually trying to install isn't a Debian/Ubuntu derivative it likely doesn't use apt or apt-get. Is it?

Post the website where you downloaded the iso from and the full name of the iso you are using.

Yes, i have turned on CSM all the time. because without it, i simply can't boot into win7 .

Code:

Your system is booting from the install media in EFI mode and you should be booting in Legacy mode with CSM enabled/on

Yes, i want the linux usb stick to boot in legacy bios boot mode (CSM is always on), but it just telling me my system is EFI enabled (during installation).
When i boot up from liveusb, the grub menu option for installation of Endea linux already indicates UEFI..

I have burn this Endea linux into usbstick using Rufus (i have specificly selected MBR) when i do the burning.

Yes, I do have i386-pc . May i know what is it for ?

Yes, i am using endea.. the apt install is not available. I should be using pacman -S instead.

I think it is from here. The latest version .
However, i have tried a older version downloaded from endeavouros website (which was a few months old iso), it was having exact same problem.. only then i tried Github version.. both having exact same problem.

Code:

https://github.com/endeavouros-team/ISO/releases/download/0-EndeavourOS-development-ISO-releases/endeavouros-devel-2020.12.25-x86_64.iso

@colorpurple, i have tried your grub cli just now.

Quote:

sudo apt install grub-pc
sudo mount /dev/sda6 /mnt
sudo grub-install --target=i386-pc --boot-directory=/mnt/boot /dev/sda

reboot, if your able to boot into endea, run
Code:

sudo update-grub

This is what i have done. I again install the linux, refuse to install /boot/efi when it prompted me warning..

Win7 loaded fine, but endea only goes in as much as grub>
Hence i didnt try

Code:

sudo update-grub

============================= Boot Repair Summary ==============================



Default settings: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to fix packages) and reinstall the grub2 of
sda3 into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s      

Confirmation request before suggested repair: __________________________________

Warning: continuing without internet would leave your system unbootable. Please connect internet.
WindowsEFI detected. You may want to retry after activating the [Separate /boot/efi partition:] option.
Are you sure you want to continue anyway?

Final advice in case of suggested repair: ______________________________________


The boot of your PC is in UEFI mode. You may want to retry after changing it to BIOS-compatibility/CSM/Legacy mode.

User settings: _________________________________________________________________

grub-probe: error: cannot find a GRUB drive for /dev/sdb4.  Check your device.map.
grub-probe: error: cannot find a GRUB drive for /dev/sdb4.  Check your device.map.
/usr/share/boot-sav/bs-cmd_terminal.sh: line 177: warning: command substitution: ignored null byte in input

This should allow to boot into system, at the grub prompt

Code:

grub> linux (hd0,3)/boot/vmlinuz-linux  root=/dev/sda3
grub> initrd (hd0,3)/boot/initramfs-linux.img
grub> boot

after booting into endea, open a terminal

Code:

sudo grub-mkconfig -o /home/boot/grub/grub.cfg

reboot this should give you back your grub menu and the ability to boot back into your system

Quote:

then it able to show windows boot menu with win7 and endea.

Are you using easybcd to boot linux from windows boot menu?

Yes, I do have i386-pc . May i know what is it for ?

The i386 directory and contents are used for a Legacy/CSM install so if you have that directory on the usb of Endea, you should be able to install Legacy/CSM. The x86_64-efi directory and its contents are used for an EFI install.
x86_64 is for 64 bit processors. i386 is for 32 bit processors.

If you scroll down in the bootinfo output to the section labelled UEFI, you can clearly see EFI entries for windows there and also that at some point, windows was installed EFI with an EFI partition (sda1). sda1 is no longer an EFI partition. It also shows the drive is not GPT which is required for an EFI install of windows. Not sure what happened there?

The bootinfoscript also shows syslinux as well as grub installed on sda3 but no grub.cfg file is shown. I would expect that executing the commands suggested above would boot Endeavour.

andrewysk · 12-30-2020, 08:32 AM

removed. duplicated

colorpurple21859 · 12-30-2020, 08:34 AM

For now this is a mess,
The ops first post about the system is full of miss-information at this point, It is a uefi system booting window 7 in legacy mode, the partition table shown in the first post pics, is no longer valid due to the reinstalls.
That op says there is an entry for endea in windows bootloader, which suggest the op maybe using easybcd.
The boot repair suggest that syslinux is install to the mbr of the drive, I think syslinux is broken based on the last few lines of post #20.
The grub set command shows grub bootcode installed at /dev/sda6 looking for the grub.cfg at /dev/sda6/boot/grub, sda6 is mounted at /home in the fstab for endea,

edit, I changed the grub-mkconfig command in post 23

When you said above, were you refering to "boot repair summary" ?

I suppose the "EFI entries for windows" was due to i did a "install grub into sda partition" that i tried out last night (using boot repair iso)..

i used easybcd once to add the linux into windows boot menu. but it does not work. (added linux in window boot menu, but does not run linux)
Not remember if i used easy bcd successfully to fix windows issue the other time or not.. i guess not (if i have windows boot issue, i won't be able to boot in windows to use easybcd).

Wow! @colorpurple21859,
Genius!...

You are the Guru of Linux !

It works.. ! my windows boot menu is working! and linux grub is working! lol

The first of the kind, Double boot menu (first windows boot menu, then grub menu)

lol

windows boot menu created by Easybcd (created when i first used it to fix boot)

5th win7 sda2 > loop back to windows boot menu

At least it works!! .
Q1.
May i know what is linux now in ? EFI or legacy ? how to check (my brain freezed.. too much info at one shoot ..lol)

Q2.
I don't know how to remove the win7 boot menu.. i suppose i can use easybcd to remove it ? so that i can straight away go into grub menu
*Since grub menu is accessed from win7 boot menu, if i remove win7 boot menu, will it causes grub is no longer accessible or no longer working ?
Q3.
In grub menu: 5th boot option (win7 sda2) is not the bootloader of win7.. hence can be remove..
i will learn to change it.

Q1: Your booting in legacy mode, in legacy mode /sys/firmware/efi directory doesn't exist.
Q2: open a terminal

Code:

sudo grub-install /dev/sda
sudo grub-mkconfig -o /boot/grub/grub.cfg

This will install the grub boot-loader into the mbr of your drive and update the grub.cfg on endea partition.
