Windows not booting after crash and shared hdd only readable

Yesterday Windows crashed from my dual-boot and since than it won’t boot up again with this message

and I have no rights on Fedora-Linux to write into the shared hdd. :confused:

I think it’s some problem regarding grub?
But I don’t know how to fix it…
Could someone help me pls?

Does fedora boot?
Have you tried using sudo to look at the content of the drive and see what may have changed?

Since you are dual booting one should see (after booting fedora) that there exist 2 folders side by side. /boot/efi/EFI/fedora and /boot/efi/EFI/Microsoft

It is quite possible that the crash within windows may have corrupted the windows portion of the device and one may need to use a windows recovery/repair procedure to fix the windows boot process. Note that doing so may also impact the ability to use grub and boot fedora so the sequence may be to 1) repair windows boot then 2) repair fedora boot.

If you can boot fedora, please post the output of lsblk -f using a copy & paste of the text and using the Preformatted text tag button </> on the toolbar above to retain formatting.

That error seems to imply a potential for corruption of the UUID of the efi partition, though if fedora still boots then digging deeper may be needed.

Thank you so much for the fast reply!
I don’t know what happened, but I turned off the PC and simply tried it one more time and now it worked again… :man_shrugging:
Yesterday and in the morning I tried it a few times and every time the same…

This may indicate an overheating problem – system needed to cool down overnight to start wotking. Both Windows and Linux allow you to monitor temperatures. You may want to open up the system and look for dust accumulation on cooling fins and fans.

You can also overnight return to “normal” with corrosion in connectors. You can try reseating all connectors. Watch for signs of corrosion when you do this. Due to the number of connectors and CPU’s in modern automobiles, auto parts stores now sell “contact enhancer”. This is often very effective for intermittent connection problems.

To understand better how to dual boot with windows, i propose you to read the following article from Arch Linux Wiki:

Just be aware that Fedora Linux could use a slightly different file structure for grub2. If you want to know more about it you coud also try to find more info about it in the search engine.
