I am going to reinstall Windows on my computer so that I can flash the UEFI/ BIOS (the computer manufacturer only supplies a .exe file). I would like to efficiently reinstall Ubuntu after that. Can you explain a time efficient way to do that?



Edit: Really, I am looking for the safest way to do this with a reasonable degree of efficiency.

    Some with .exe files also offer a DOS file, so you can create a DOS bootable flash drive to run update.Most better systems now let you run update directly from UEFI with update on a FAT32 partition. And a few new UEFI systems will update directly from Linux with fwupd.org/lvfs/devicelist & fwupd.org/vendorlist

The most efficient way is to find a Live Windows image and boot from it.



You will be able to flash BIOS from it.



But beware that in some cases it is not a good idea to flash a new BIOS. About a week ago I flashed a new BIOS to an Asus laptop using a BIOS utility (built in into BIOS called EasyFlash).



After that I lost touchpad in Ubuntu and had other problems. I couldn't downgrade BIOS using the same utility because it didn't allow to flash older BIOS.



So I had to use a Live Windows image where I successfuly downgraded BIOS using /nodate switch.



So if you don't have a very strong reason, and everything works fine, don't upgrade BIOS. Ubuntu will take care of CPU microcode.

    The most time efficient method of putting an existing Ubuntu installation back on your system is to boot from a thumb drive, do a complete image backup of the entire drive to another (large enough) storage device, then restore that image backup after you're done with Windows.



    I'll link an article on how to do this (be careful; you can erase everything as easily as backing it up), but dd is the core command for these operations.






    share|improve this answer


























    • My understanding is that when I install a new UEFI, there are some things that need to change, regarding other parts of the system. I believe the bootloader is one of them. So don't we need a way to naturally create some of the "install" files?

      – whitelightning
      21 hours ago











    • Considering that full disc backups take several hours, this is hardly "most time efficient". Even opening the laptop and changing the drive would be faster.

      – jpa
      13 hours ago











    • @whitelightning Boot configuration is stored on the disk on a EFI System Partition, so restoring disk image will revert those changes as well. But if you want to do it fast, use Clonezilla for imaging, not dd. Clonezilla will only backup used space.

    • @gronostaj When I install Ubuntu, there is an EFI system partition, uses fat32 file system. The Ubuntu installation automatically creates that. You are saying that we don't want that moved over, right?

    If your .exe flasher tool does not need installation, then you may be able to do this from the Windows installer disc.



    Download a Windows 10 installer iso image from Microsoft of the appropriate bitness (32-bit or 64-bit). If you visit the site from Windows, then Microsoft wants you to download their "Media creation tool", which can either download an iso or create a bootable USB drive. I believe the site simply offers the iso file if you visit from Linux, but I haven't tried. This is a free download, and you don't need a license since you won't be installing.



    Boot the computer with the installer disc. Progress through the installer until you come to the "Install Now" screen, don't click that button, and press Shift + F10 to open a Command Prompt window. From there you can do many things, for example: Plug in a USB drive with your flasher .exe on it, navigate there (you may have to try a few drive letters to find the correct one), and execute it.

              The most time efficient method of putting an existing Ubuntu installation back on your system is to boot from a thumb drive, do a complete image backup of the entire drive to another (large enough) storage device, then restore that image backup after you're done with Windows.



              I'll link an article on how to do this (be careful; you can erase everything as easily as backing it up), but dd is the core command for these operations.

              • My understanding is that when I install a new UEFI, there are some things that need to change, regarding other parts of the system. I believe the bootloader is one of them. So don't we need a way to naturally create some of the "install" files?

              • Considering that full disc backups take several hours, this is hardly "most time efficient". Even opening the laptop and changing the drive would be faster.

              • @whitelightning Boot configuration is stored on the disk on a EFI System Partition, so restoring disk image will revert those changes as well. But if you want to do it fast, use Clonezilla for imaging, not dd. Clonezilla will only backup used space.

              • @gronostaj When I install Ubuntu, there is an EFI system partition, uses fat32 file system. The Ubuntu installation automatically creates that. You are saying that we don't want that moved over, right?

              If your .exe flasher tool does not need installation, then you may be able to do this from the Windows installer disc.



              Download a Windows 10 installer iso image from Microsoft of the appropriate bitness (32-bit or 64-bit). If you visit the site from Windows, then Microsoft wants you to download their "Media creation tool", which can either download an iso or create a bootable USB drive. I believe the site simply offers the iso file if you visit from Linux, but I haven't tried. This is a free download, and you don't need a license since you won't be installing.



              Boot the computer with the installer disc. Progress through the installer until you come to the "Install Now" screen, don't click that button, and press Shift + F10 to open a Command Prompt window. From there you can do many things, for example: Plug in a USB drive with your flasher .exe on it, navigate there (you may have to try a few drive letters to find the correct one), and execute it.
