From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hello guys,

I bought a new SSD (WD black sn770 2 TB) for my laptop and I also got a USB-C hub which includes a slot for an SSD. My old SSD is 512 GB

So here is what I want to do: I want to change to Linux from Windows 11. I want to keep my old SSD in the USB-C hub with Windows still installed in case I need it for some software/games but Linux will now be my main OS.

Are there any tips or recommendations on things I should look out for when doing this?

I also don't know if I can just install Linux in what is ATM the external SSD and then swap it out afterwards with the SSD inside the laptop without having to do anything extra and if it will just work like that.

I plan on following this tutorial: https://www.youtube.com/watch?v=bfWdnCIrcxk.

Also any recommendations on how I can safely transfer some files? Do I need a special software?

In case interested this is the distro that I plan on using: https://garudalinux.org

As a side note, I did check that the SSD is compatible with my computer and has everything right.

Linux bootloaders discover the correct linux volume by UUID (which is in the filesystem), or PARTUUID (which is in the GPT table). It'll look at every drive, and when it sees the matching one it'll look in that partition, find the kernel & initrd, suck them into ram, and launch the kernel.

The main problem with moving drives around is - where is the EFI firmware looking for the bootloader in the first place? If you read efibootmgr, the efi data is pretty simple and very much tied to a hardware port. The EFI takes the most preferred bootloader entry, goes to that drive, and runs a file like "\EFI\grub\grubx64.efi". If that file isn't right there, the EFI isn't going to look elsewhere for it.

There is one bootloader name that EFI will pluck out of the blue and (smash the Fx key) offer to you as a boot option - "\EFI\BOOT\BOOTX64.EFI". Self booting usb installers use that, but you could use it too. Put all the other files that go along with the bootloader in with that boot folder, and rename the appropriate .efi to bootx64.efi.

One thing that I've done on odd setups is to put rEFInd on the efi partition as the boot\bootx64.efi loader. It'll do a pretty fancy job of detecting what's bootable (may need an additional filesystem_driver.efi), or even chain into grub to finish the startup.
