-at reboot, be sure that on BIOS the **GRUB** entry has the first priority over Windows Boot Manager. Then, it should work.
+Finally, for fixing also the Linux access, burn Athena OS ISO on a USB and follow the steps explained at [Post-installation](/en/installation/install-persistent-usb/#post-installation) section.
 
-Once landed on your working and fixed Linux environment, open the terminal and run:
+#### Several boot entries have been disappeared
+
+In case you are in dual boot and some entries are not shown anymore (i.e., Windows Boot Manager if you have Windows in dual boot), enter in Athena OS and run:
 ```
 sudo grub-mkconfig -o /boot/grub/grub.cfg
 ```
-to restore the Windows entry in GRUB in case it is missing. Reboot the system to check all GRUB entries are working as intended.
+Then reboot.

-Don't remove any other files or folders on mounted directories otherwise they will be deleted also on the related device and the boot manager could break.

-In case you previously formatted your EFI partition, its UUID could be changed, so, at this point, when you boot, you could get an error and be dropped on the emergency shell:
+The message:
 ```

-replace `/dev/nvme0n1p1` by your EFI partition device. This command gives you the valid UUID of your EFI partition, for example:
+### Display Managers
+
+#### GDM: login background turned to grey
+
+It should be caused by an update of GDM or GNOME packages that restored the default gresource theme file. To restore the Athena GDM theme, run:
 ```
-/dev/nvme0n1p1: UUID="E856-25BA" BLOCK_SIZE="512" TYPE="vfat" PARTLABEL="EFI system partition" PARTUUID="71e827d6-2276-46f2-816b-881e51c53d30"
+sudo pacman -S athena-gdm-config

-Then, you must edit **fstab** to replace the old EFI UUID with this new one. So, open the **fstab** file by:

+#### Bloodhound

+On Bloodhound, when neo4j database is run by `sudo neo4j console`, we can get some errors like:
 ```
-nano /etc/fstab
+Exception in thread "main" java.lang.LinkageError: Cannot to link java.nio.DirectByteBuffer
 ```
-and you should get something similar to:
+For solving it, just run neo4j server by `systemctl start neo4j`. You can check the proof that the server is correctly running by `systemctl status neo4j`.
+
+#### Conda
+
+`conda activate` continues to show the prompt **(base)** instead of **(test)**.
+
+The issue is related to the usage of `no-repeat-flag` in `.bashrc`. To solve this, add the following code inside `.bashrc`:
+```bash
+if [[ $1 != no-repeat-flag  ]]; then
+    __conda_setup="$('/home/kumquat/miniconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
+    if [ $? -eq 0 ]; then
+        eval "$__conda_setup"
+    else
+        if [ -f "/home/kumquat/miniconda3/etc/profile.d/conda.sh" ]; then
+            . "/home/kumquat/miniconda3/etc/profile.d/conda.sh"
+        else
+            export PATH="/home/kumquat/miniconda3/bin:$PATH"
+        fi
