I am going to reinstall Windows on my computer so that I can flash the 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.

  I would just make a +minimum size partition on hard drive for a Windows install. Have ubuntu install disk handy if grub needs fixing after. Leave ubuntu install alone.

  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

  Also, even though it's a .exe file, the BIOS flash programmer may (more likely than not these days) still read it. Dell machines, for example, allow you to load any flash onto a FAT32 USB key and the BIOS will find it and load it using the built-in flashloader. (F12 menu)

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.

Disconnect your Ubuntu system drive, connect an old spare or used drive, install Windows on it, and do the BIOS update (if, as Pilot6 explained above, if you absolutely, positively, have to update the BIOS). Then, disconnect the old drive, put your Ubuntu OS drive back on, and you're ready to know, secure in the knowledge that Windows did not corrupt Linux.

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.
