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.

Old laptop suddenly won't recognize Linux boot drive (feddit.nl)

I'm in a really weird situation, yesterday I installed Linux (Fedora Kinoite) on my mothers laptop (An old Asus F550C) and it worked perfectly fine. Great! Or so I thought.

We needed a few files from Windows 10, so I put that drive in, put the files on a USB stick, put the Linux drive back in and... Nothing? It recognizes the drive, but not the Linux boot option. I put the drive in my pc and it works fine, the boot drive is also still detected in the laptop just fine.

What the hell could it be??

  • The laptop is fine (Windows drive works perfectly)
  • The drive is recognized in bios (But not the boot option)
  • The drive works fine in my desktop and can boot to Fedora
  • The laptop can boot to the USB drive I used to create the install
  • Yesterday it worked just fine
  • I went through the bios, but can't find any settings related to this (Secure boot did not fix it)

Update: the issue is solved! Windows somehow wiped the efiboot entry.

I mounted the drive from a live usb and ran

sudo efibootmgr --create --disk /dev/sda --part 1 --label "Fedora" --loader '\EFI\fedora\shimx64.efi'

After rebooting, the system works again!

Make sure that Windows Fast Startup is turned off. I don't know if that's specifically the problem here, but in my experience quite a few "everything's fine, it should be working!" boot issues have been resolved by booting into Windows, turning off Fast Startup, and then doing a full shut down before going back to Linux, especially on laptops.
