Been running dual boot on daily driver for maybe 1 month now. Fedora is doing very nicely, but booted into Windows to see if it needed to update. It wanted to do the 23H2 update. I didn’t take a picture of the screen, so I can’t say more. There is a log file, but I also didn’t take a picture of the screen where they said the log file was stored, and I can’t find it now. Anyway after the computer reset, I reselected Windows boot manager to finish the update, but at that point it just restarted again. I selected Windows boot manager again, and after 2 reboots it went into the Safemode diagnostic… seems the only fix is to reinstall Windows. If I do that won’t I loose Fedora. I have been playing several games on Fedora and don’t want to loose progress. (the main game is Horizon Zero Dawn on Steam. It’s installed on my Fedora partition, but I think it’s save files are local. May be able to back those up…) (it says Coud status - Up to date, so maybe it’s saves are in the Cloud) Also don’t want to have to resetup everything in Fedora. Is there a way to reinstall Windows 11, then redo grub? Without reinstalling Fedora? I have Windows 11 installed on a 1TB SATA ssd, and Fedora 40 installed on a 4TB m.2 ssd. So they are on seperate drives. Today I have an exam for an online college class, and the exam requires Honorlock, which is a Chrome extension. I tried running it in Fedora, but it didn’t seem to function correctly. So I took my last exam in Windows. I don’t know if I can get the exam working in Fedora Chrome… so I need this fixed TODAY, but I don’t want to loose everything in Fedora.
Found the following link. Could I reinsall windows, then afterwords try the other person’s fix to fix grub? Repair/Reinstall GRUB after Windows 11 Update (Dual Boot Fedora F39)
Ok reinstalled Windows 11, but when I switched back to the Fedora option in my boot options of my bios, I can no longer select Windows Boot Manager in grub. it doesnt work. Fedora errors out too, but if i keep rebooting and selecting fedora after a few tries it will boot into Fedora. I tried this fix listed above, but it didnt work.
