    Re: Dual Boot Latitude E5440

    Since Windows is UEFI, you need to always boot system & any repair, or install flash drives in UEFI mode.





    I typically suggest using Ubuntu live installer & add Boot-Repair using ppa to the...

    Re: Grub has made windows hdd unbootable

    Some require all 4 chars for efibootmgr -o command.
    And no space after comma.

    You do not have typical Windows install, but since you have Windows UEFI boot entry it looks like an UEFI install....

    Re: Grub has made windows hdd unbootable

    You show a newer UEFI system, but most Windows 7 installs were BIOS on MBR partitioned drives.
    Only about 2012 when Microsoft required vendors to install Windows 8 in UEFI mode to gpt drives did...
  4. [ubuntu] Re: No bootable devices found after BIOS update on Dell XPS 9370 (ubuntu preinstalled

    If UEFI/BIOS cannot see drive, no software or operating system will see it.
    UEFI/BIOS scans system for drives & other hardware & writes that info to drive for operating systems to use.

    I might...

    Re: help boot repair error

    Some systems just do not want to boot from a caddy.
    Even though a caddy slot had DVD that is bootable.

    But some have configured boot on internal drive & system on caddy drive.

    Re: help boot repair error

    Is sdb also a removable drive?
    If so that is the issue.

    Windows requires gpt partitioning for UEFI boot.
    Ubuntu & then I assume Elementary allows you have install on sdb as MBR, but have UEFI...

    Re: help boot repair error

    Elementary is not an offical flavor of Ubuntu.
    Moved to other OS.

    You have sda as gpt partitioned for UEFI, but sdb as old MBR(msdos).
    UEFI installs in sda look ok.

  8. [ubuntu] Re: No bootable devices found after BIOS update on Dell XPS 9370 (ubuntu preinstalled

    You show no drive, just USB flash drive.

    Did UEFI update reset UEFI settings?
    And then turn Intel RST/RAID back on. Check if still AHCI.
    Otherwise check connections to make sure drive connected,...

    [SOLVED] Re: Ubuntu 21.04 partition table

    Check this:
    sudo grep -E -i "error|warning" /var/log/dmesg

    And then see if you can find the error in dmesg and if it tells more info.
    Perhaps like this?
    sudo grep -E -i "partition"...

    You should just need to copy /home.

    [SOLVED] Re: Ubuntu 21.04 partition table

    Normally gdisk would show any errors.
    That entry is typical correct gpt table.

    Do you still have live installer plugged in?
    Depending on how you made live installer, it does not use partition...
  13. Re: Can write to NTFS data partition, can't to Windows OS partition

    Well, generally better not to write into the Windows system partition and use a shared NTFS partition for data.

  14. [lubuntu] Re: Can't boot Lubuntu 20.04 after installation

    I do recommend gpt over the 40 year old MBR.
    I converted my first drive to gpt in 2011 for Ubuntu with XP on a separate MBR drive. Then found I had to have the bios_grub partition for grub to...

    [SOLVED] Re: Ubuntu 21.04 partition table

    It shows gpt partitioning with an ESP and a bios_grub partition.
    So could be UEFI boot or BIOS/CSM boot depending on which version of grub is installed.

  17. [lubuntu] Re: Can't boot Lubuntu 20.04 after installation

    Did you change from last Boot-Repair report?

    You want either UEFI with gpt partitioning.
    Or BIOS/CSM/Legacy. And you can use MBR or gpt, but gpt then requires a 1MB unformatted partition with...
  18. [lubuntu] Re: Can't boot Lubuntu 20.04 after installation

    Both reports show grub installed correctly to MBR for BIOS boot.
    You just need to confirm your UEFI/BIOS is set for BIOS/CSM boot.

    My motherboard (Asus) would only boot in UEFI mode with UEFI...

  22. Re: How come installing Xubuntu 20.04 on legacy mode doesn't work?

    Again, how you boot install media controls whether you install in BIOS/Legacy or UEFI.
    The default setting in UEFI is only for your installed system, once installed.
  23. [SOLVED] Re: I completely lost my partition and I'm not sure what happened

    /home has all your user settings, mostly in hidden .xxx files. And it has all your user data, unless you also use separate data partition(s).

    If you edit system files in /etc like grub, then you...
  24. [ubuntu] Re: Unable to instal Ubuntu 20.04.2.0 on WIndows 7 (Dual Boot)

    The other thing that Windows does is convert to a proprietary dynamic partitioning scheme that Linux does not normally work with. Shown as SFS or LDM.

  25. Re: How come installing Xubuntu 20.04 on legacy mode doesn't work?
