    Re: Unable to boot Windows 10 even after running boot-repair in Ubuntu

    Yes I have made a good Windows backup.
    Windows booted up without the need of a recovery flash drive, when I disabled Load legacy option ROM in the system setup and selected the 'save settings' option and not the 'save and reset settings' option.
    At the moment both Ubuntu and Windows boot up properly, though I need to use the Boot menu (F12) to toggle between them.
    I am now not able to see the nvme drive in Disks on Ubuntu:

    How do I make Ubuntu locate the nvme drive?
    I haven't checked for the following, it would be great if you could direct me on how to do so:
    Have you updated UEFI and SSD firmware?
    Is/are drives set in AHCI mode?
    Is Windows fast start up off?
    Thank you.

    Did you mention brand/model system?
    Most UEFI update from Windows.
    And most also update from within UEFI if you have downloaded the update file from your vendors site into a FAT32 partition. (not the .exe as that is the Windows update).
    Many new systems now update from Linux.
    https://github.com/rhboot/fwupdate/b...ster/README.md
    https://fwupd.org/lvfs/devicelist &
    https://fwupd.org/vendorlist

    I do not have Windows and download update file into my ESP. I made the ESP a bit on the larger size, but had to change permissions to use it in Ubuntu.
    I also have a Samsung NVMe SSD. That I was able to download a bootable ISO. It looked like an old DOS screen, was unique to my model and only checked & then did update.

    Fast Start up off (always on hibernation), note that Windows turns this back on with updates, SHIFT + Shut down button

    fwupdmgr update doesn't return anything.
    Restarting the system still doesn't display grub menu.
    Haven't checked for fast startup (not there in my system setup), will revert on it soon.

    Did you try the rEFInd suggestion in post #14?

    No, I have not tried it yet.
    As mentioned in earlier posts, the Windows booting issue got entirely fixed.
    Now the only issue is the GRUB menu not showing up.
    Do you suggest I use rEFInd at this point ? If so, then what should be the way I go about it?

    You can first try use the usual grub update command (ignoring rEFInd experiment)
    and if that does not work
    follow the rEFInd installation commands in post#14

    You will be guided by a menu.

    rEFInd does not destroy classic Grub it simply adds another folder in /boot/efi/EFI

    On external Ubuntu SSD mine looks like this ..
    /boot/efi/EFI/Boot
    /boot/efi/EFI/Dell
    /boot/efi/EFI/refind
    /boot/efi/EFI/tools
    /boot/efi/EFI/ubuntu

    and in refind folder there are further folders and file.

    The important loader is refind_x64.efi

    and refind.conf allows customisation of the rEFInd menu.

    rEFInd expects to be installed in a preformatted ESP with boot flags enabled. But you can have multiple ESP partitions. I have one in Windows internal drive and I have one in my external SSD for Ubuntu 18.04. My policy now is through LiveUSB and Gparted, create an ESP partition for each Ubuntu installation so that it can be portable (works even when Windows drive disconnected or boot flags disabled temporarily).

    But do read Rod Smith guides.

    If you have Windows you can do UEFI update from it.
    But UEFI update resets many settings in UEFI to defaults & sets Windows as first in UEFI boot order.
    Grub on major updates also sets grub as first in UEFI boot order.
    I have 5 or 7 settings in UEFI, some optional that I have to redo with every UEFI update.

    I have used rEFInd for my emergency boot flash drive and it works well.
    Have seen posts where other users with difficult systems used rEFInd. It really is just another menu system as you still use grub to boot. Grub is both a menu & boot loader. And UEFI has menu. So multiple choices.

    Usually Dell works and Alienware is based on Dell's UEFI. But typically needs updates.
    And just about every system seems to need some setting or the other to work.
